                                    DEDICATION

    EDDY is dedicated to the memory of Dean W. Anschultz, a good friend and a
   GOOD man, in every sense of the word. His ideas, encouragement, and uncanny
       abilities as beta-tester have been the major driving forces for the
                 continuing development and improvement of EDDY.

                          Dean, you are missed.  R.I.P.

   1. What Does EDDY Do?

   EDDY (for EDit DirectorY), a shareware program modestly billed as the
   "World's Greatest Disk Utility!", lets you do WHATEVER you want with your
   files, directories and disks, and minimizes the keystrokes needed to do it.

   EDDY is ALL of these...
        Full-screen directory editor
        Disk and directory manager
        DOS shell
        Sector editor
        RAM editor
        File finder (by name, attributes and/or timestamp)
        File viewer/patcher/comparer
        File backup utility
        String finder/replacer (hex and/or ASCII)
        Data recovery utility
   ...and MUCH more!

   Most of what EDDY does isn't new; the program was developed as a test of
   the "Build a better mousetrap..." theory of economics.  However, it often
   provides a "new twist" on approaches to old problems.

   Some of the features and capabilities that have been reported by users as
   particularly helpful (along with some of my own ideas about what's neat)
   are described in Appendix A, "Why Use EDDY?", at the end of this file.

   EDDY is also cheaper (but NOT free!  It is not in the public domain.) EDDY
   is "user-supported" software, or "shareware".  Distribution and use of EDDY
   are subject to the conditions described in Section 26.

   EDDY's revision history, summarizing the features and enhancements in this
   and earlier versions, is available in the file "EDDY_HST.DOC".


   1.1 EDDY is Ready if You Are

   EDDY needs the following hardware and software:
   - IBM PC, XT, AT, PS/2 or close compatible
   - A monitor that can accommodate 25x80 text mode display
   - At least 180K of available memory

   of 66 lines -- see Section 3.2, option "/9").

   1.2 Installation

   You may use EDDY just as it comes, directly from the distribution disk.
   However, you'll probably want to keep the distribution disk as a backup,
   and copy the files "EDDY.COM" and "EDDY.AUX" to your hard disk, if you have
   one.  There is no other special preparation required.

   To start getting familiar with EDDY, make the directory (or diskette)
   containing EDDY.COM current, type "EDDY" (without the quote marks), then
   [Enter].  That's all there is to it!  There are extensive,
   context-sensitive HELP facilities -- press [F1] -- and pull-down menus --
   [Alt+F1].  HELP includes all of the basic information needed to use EDDY.
   There is no danger of damage to your disk data, because no changes will be
   made to any of your directories or files until you tell EDDY to do so.

   If EDDY's display is blurred, unreadable, or strange-looking, try "EDDY/M".
   If this works, create a customized copy with option /M on (See Section 24).


   1.3 EDDY's Display

   This is a sample of a typical EDDY display, which might have resulted from
   entering the command "EDDY A:"

   The rectangles on the right side of the screen are used as "click" buttons
   with a mouse; clicking on them results in the indicated action.  They are
   actually displayed as neat boxes with double outlines, but those characters
   don't show up well on many printers.  Although primarily intended to
   facilitate using a mouse, these boxes may also be used with the keyboard.

   At the right edge is a scroll bar, shown here only as an approximation of
   the actual display.  The scroll bar is also intended mainly for mouse use
   (see Section 2.1.3), but may be used with the keyboard, too.

   1.3.1 What Country Are You From?

   If you use a date format other than the USA standard "mm-dd-yy", EDDY will
   use the format you choose (usually by use of "COUNTRY.SYS" in your
   CONFIG.SYS file).  The column heading above the date will indicate which
   format is being used, showing "mmddyy", "ddmmyy" or "yymmdd", accordingly.

   1.3.2 Printing

   To print the directory in the same format as the display, press [Alt+p].
   If you want to stop before the entire directory has been printed, press
   [Alt+p] again; [Alt+p] is a toggle key.

   Pressing [Alt+Shift+p] sends a single formfeed to the printer.


   1.4 What You See Is What You Edit (WYSIWYE?)

   EDDY starts by displaying the entries in the selected directory.  You may
   edit those entries, including filename, date, time and attributes.  Just
   move the cursor to the field you want to edit, and type your changes.

   You may also select files to be patched, copied, moved, deleted, etc.  All
   changes will be shown on the screen, but no changes will be made on disk
   until you tell EDDY to do so.  EDDY applies the requested changes to disk
   when you enter UPDATE mode, by pressing [Enter].  EDDY will ask you to
   confirm that you want to write to disk (by pressing [Enter] again), and
   will give you the choice of returning to EDIT without making any changes.

   At any time before writing changes to disk (in UPDATE mode), you may change
   your mind and UNDO the changes.  You may UNDO changes to the current file
   with [F2], or you may UNDO all changes to all files by pressing [^F2].

   1.4.1 Working and Target Directory

   The directory displayed by EDDY is referred to as the "working directory".
   If any files are copied or moved, they are put in the "target directory".

   The working and target directories may be given on the DOS command line
   when you execute EDDY.  The directories may be changed at any time (see
   Section 5).  If the command line doesn't specify any directory, the current
   directory on the default drive will be the initial working directory.

   EDDY v.7c User's Manual   Copyright (C) 1987-93 by John Scofield  page   4



   1.4.2 Sequence & Sorting

   The information in this section concerns the sequence of the display on the
   screen; you may also sort the directory permanently, on the disk.  Refer to
   Section 22 for more details on this.

   EDDY's starting display is sorted by file name.  The sequence is indicated
   on the last line of the display.  In Figure 1-1 the last line shows the
   notation "seq=N", indicating sort by NAME.  Possible values of "seq" are:

     "D" - sorted by DATE, time, name & extension
     "E" - sorted by EXTENSION & name
     "H" - sorted by HOUR & minute
     "N" - sorted by NAME & extension
     "S" - sorted by SIZE, name & extension
     "U" - UNSORTED; i.e., in the sequence stored in the directory by DOS

   EDDY builds the first display in name sequence.  If you would prefer a
   different initial sequence, refer to Section 3.2 for information on the
   use of option /1 to change the sort sequence.

   To change the sequence, press [Alt+d], [Alt+e], [Alt+h], [Alt+n], [Alt+s]
   or [Alt+u].  The directory will be re-sorted in the sequence requested, and
   the "seq" field on the bottom line will be updated.

   Subdirectories are an exception:  except for UNSORTED sequence, all
   subdirectories are grouped at the top of the display, before any file
   entries.  This is to make it easier to move around the disk, from
   subdirectory to subdirectory, using the LOOK command (see Section 8.1).

   To invert the order of the display (e.g., to get the files with the most
   recent dates at the top), press [Alt+i].  When the display is inverted, an
   up-and-down arrow appears just to the right of the "seq" field.

   Once the display has been inverted, it remains that way until [Alt+i] is
   pressed again; [Alt+i] is a toggle.  Thus, if the display is by date,
   inverted (i.e., newest date first) and you press [Alt+s], the resulting
   display will be by size, inverted (biggest files first).

   Inverting is different from sorting.  Inverting just reverses the order of
   the list of files currently displayed, and makes any later sort produce an
   inverted list.  Inverting does not cause the directory to be reprocessed.

   Under some unusual circumstances, you may see the following warning message
   when you enter a command to re-sort:
               "Sorting cancels changes not UPDATEd. Sort (y/n)?"

   This occurs when you have very little memory available for EDDY's use, and
   there are lots of pending changes when you enter the command.  EDDY will
   always handle at least 160 pending changes without this problem.

   EDDY v.7c User's Manual   Copyright (C) 1987-93 by John Scofield  page   5



   1.4.3 Number of Files

   With displays containing more than one page, an arrow, pointing up and/or
   down appears in the upper right corner to show that there is more data to
   be viewed by scrolling in that direction.

   EDDY can display up to 400 or so directory entries, depending on available
   memory.  This is a limit on the display, not on the size of directories.
   If you had, say, 500 files in directory "\BIGDIR", and you wanted to work
   with assembler source files, typing "EDDY \BIGDIR\*.ASM" would yield a
   display of all .ASM files (up to around 400).

   If EDDY's display capacity is exceeded, the number of files indicated on
   the third line ("109 files" in Figure 1-1) will be replaced by two numbers.
   The first is the number of files displayed, and the second is the
   additional number of files which would have been displayed if there had
   been enough room.  In Figure 1-1, if the directory had contained 480
   entries, the "109 files" would be replaced by "400+0080 files".

   When EDDY finds too many files to display at once, files are "dropped off"
   the end of the list according to the current sequence.  For example, if the
   sequence is by date, inverted, the files with the oldest dates would be
   dropped.  Sorting again will reprocess the entire directory, dropping those
   files which come at the end of the list according to the new sequence.
   (Inverting will redisplay the current list in the opposite order.)

   It is possible to display up to double EDDY's capacity, by first displaying
   the files in one sequence and then inverting and re-sorting.  Suppose a
   directory had 500 entries, and was displayed in "Name" sequence.  The first
   400 files would be displayed.  To see the rest of the files in this
   directory, press [Alt+i] followed by [Alt+n].  This would show the rest of
   the files, starting from the opposite end, in inverted sequence.


   1.4.4 File Sizes & Disk Capacity

   The display also shows the number of bytes used by the files in the
   display, and the number of free bytes left on the disk.  Both are multiples
   of the disk cluster size.  Space occupied by subdirectories normally is not
   included in the display.  See the next Section for more on this.

   File sizes are counts of bytes of data in the files, rather than bytes on
   the disk assigned to the files; thus, the "bytes used" normally doesn't
   equal the total of the file sizes.

   If the directory has more files than EDDY can display, the "bytes used" is
   the total for all files (i.e., the "350+0120 files" in the example).

   For diskettes with no subdirectories, and with all files displayed (*.*),
   the bytes used plus bytes free should equal the disk capacity.  If not, try
   running "CHKDSK" to see if there are some stray sectors to be reclaimed.

   EDDY v.7c User's Manual   Copyright (C) 1987-93 by John Scofield  page   6



   1.4.5 Directory Sizes

   Normally, for a subdirectory, you'll see "<DIR>" in the size field, and the
   space occupied by the directories won't appear in the "bytes used" summary.
   However, these directories do occupy space on the disk.  A single entry
   (file or subdirectory) in a directory requires 32 bytes; thus, 64 entries
   fit in a typical 2048-byte cluster.  If a directory has more entries than
   can fit in a cluster, more clusters are allocated to the directory.

   If you'd like to see how much space is actually occupied by the subdirec-
   tories on your disk, use option /D (see Section 2.3 for a discussion of
   options).  But be prepared to wait longer for the display to be built; DOS
   does not report directory sizes through its normal services.  EDDY must
   interpret low-level format and FAT information directly, reading the
   relevant sectors of the disk to get this information.  The sizes are shown
   between "<" and ">" brackets (e.g., "<2048>", so directories are still
   easily differentiated from files in the display.

   When displayed, directory sizes (except for the "." and ".." entries) are
   included in the "bytes used" summary.  The size of the "." entry is the
   size of the directory being displayed; it is not part of the space
   allocated to the files in that directory.  The ".." entry is also not
   included in the summary figure.  If the ".." entry is actually the root
   directory, you will see "<ROOT>" instead of a size, as the root size is
   fixed by the formatting process, and does not occupy space that would
   otherwise be available for file storage.

   If you delete entries, the directory space is NOT released; directories
   always stay as large as the most space that was ever required for them,
   even if there are NO files currently in the directory.  The only way to
   free up unused directory space is by deleting the directory itself.

   2.  Telling EDDY What To Do

   As mentioned above, EDDY's basic display provides full screen editing
   capabilities -- just move the cursor to the data you want to change, and
   type in the new data.

   The cursor may be moved with the keyboard or by mouse.  A "scroll bar" is
   also available.  [NumLock] state (ON/OFF) is always ignored by EDDY --
   i.e., treated as OFF, unless [NumLock] is pressed while EDDY is running.
   Once it has been pressed, its state is recognized and treated accordingly.

   Other capabilities of EDDY are called upon by using commands.  Commands may
   be entered in whichever of the following ways you find most convenient:

         - Hot Keys
         - Pull-Down Menus
         - Command Line


   2.1 Moving Around

   Some fields on the screen, such as file size, can't be edited.  These
   fields are "protected" so that the cursor can't be moved to that position.
   Instead, it will move to the next unprotected position.

   2.1.1 Using the Keyboard

   In this document, key names are enclosed between "[" and "]" delimiters.

   The "arrow" characters are not printable in general, so the cursor control
   keys are indicated by the word -- left, right, up, down -- for the
   direction of the arrow that's printed on the key cap.

   In key names, the prefix "^" means the key is pressed at the same time as
   the [Ctrl] shift key.  The notations [Alt+key] or [Shift+key] mean that the
   [Alt] or [Shift] key is pressed at the same time as the indicated "key".

   EDDY's cursor is moved around in the display as follows:

     [Up]     - move up 1 line           [PgUp]   - up 1 page
     [Down]   - move down 1 line         [PgDn]   - down 1 page
     [Home]   - move to top of page      [End]    - move to end of page
     [^Home]  - display first page       [^End]   - display last page
     [Left]   - left 1 column            [Right]  - right 1 column
     [Shift+Tab] - left 1 field          [Tab]    - right 1 field
     [^Left]  - move to column 1         [^Right] - move to last column

     [/] - move to date field                [:] - move to time field
     [.] - left edge, except in filename field [.] moves to extension
     [+] - move to attribute field, except in attribute field [+] toggles

   EDDY v.7c User's Manual   Copyright (C) 1987-93 by John Scofield  page   8


   2.1.2 Using a Mouse

   EDDY reacts to mouse movement just as if you had used the arrow keys in a
   corresponding way (UNLESS you have moved all the way right, past the end of
   the highlighted area, to the scroll bar -- more on that in Section 2.1.3).

   Pressing the left mouse button ("left clicking") in EDIT mode is the same
   as pressing [F3].  With the cursor on a directory line, EDDY makes that the
   new working directory; a left click on a file line LOOKs at that file.
   This may be changed -- see 2.1.2a, below.

   When EDDY is waiting for confirmation that you want to proceed with some
   action, a left click means "Yes, proceed".  A right click is the same as
   [Esc], or "No, don't proceed".

   If EDDY asks for either [Enter] or [^Enter], a left click is the same as
   [Enter], and a double left click is the same as [^Enter].

   Click the left button while the cursor is on the "MENU" or "HELP" box at
   the right side of the screen to get the corresponding display.  Click the
   right button to return to the main body (left portion) of the display.  You
   may move the cursor around elsewhere in this area, but it has no effect.

   a. Changing the Button Command - [Alt+m]

   To change the command used for the left mouse button in EDIT mode, press
   [Alt+m].  Next, press the button for the command that you prefer to use.
   Also, see the following section.

   b. If You're Left-handed

   After [Alt+m], you may click the right mouse button instead of pressing a
   key.  This swaps the use of the left and right mouse buttons, which is
   preferred by some left-handed people.  In that case, all descriptions of
   the right button actions actually apply to the left button, and vice versa
   (except in this paragraph -- the right button is ALWAYS used to swap).

   In the display line shown at the top of this page, note the "*" at the left
   end of the series of "^"s; this "*" indicates that the primary mouse button
   is the left button, corresponding to the usage described in this manual.
   If you swap the button usages (making the right button primary), the "*"
   will be shown at the right end of the "^"s.

   EDDY v.7c User's Manual   Copyright (C) 1987-93 by John Scofield  page   9



   c. Mouse Sensitivity - [Alt+Shift+m]

   If your mouse reacts too quickly or too slowly when you move it, you can
   adjust the sensitivity.  Press [Alt+Shift+m], and you'll get a display
   showing the current speed relative to the maximum and minimum possible.
   Move the mouse left to slow the mouse down or right to speed it up.
   Left-click when the speed is the way you like it.

   If you customize EDDY, the sensitivity you select will be the default in
   the customized copy.

   Some mouse drivers are not fully compatible with the Microsoft standards,
   particularly with respect to how the sensitivity is handled.  If you're
   using one of these drivers, EDDY won't be able to adjust the sensitivity.

   2.1.3 Using the Scroll Bar

   At the far right edge of the screen you'll see a single, shaded column with
   an arrow at either end; this is the "scroll bar".  Its main purpose is to
   give you an easy way of moving the display up or down with a mouse,
   although you may use it with the keyboard, too, if you wish.

   The scroll bar also shows a highlighted box (the "slider").  The position
   of the slider on the scroll bar gives you an approximate indication of how
   much further you must scroll to get to the end of the display.  For
   example, if EDDY has selected 90 files for display, and your current file
   is the 30th, the slider will be about 1/3 of the way down on the scroll
   bar.  If you're on the 90th file, the slider will be at the bottom.

   To use the scroll bar, move the cursor to a position either above or below
   the slider, and press the left mouse button (or [Enter]).  The display will
   scroll up if the cursor is above the slider, or down if below.  (If the
   cursor is right on the slider, no scrolling occurs.)

   The amount of scrolling depends on where the cursor is located.  If it is
   on one of the arrows at either end of the scroll bar, the display will
   scroll a line at a time in the indicated direction.  Elsewhere on the
   scroll bar, each click moves the display a page at a time.

   Holding the left mouse button (or [Enter]) down causes the scrolling action
   to repeat.  If you are paging, this can cause the cursor to alternately be
   above and below the slider, which will keep repeating the same two pages of
   the display.  Not terribly useful, but being documented makes it a feature
   rather than a bug.

   Click the right mouse button (or press [Esc]) to move quickly back to the
   main body of the display.  You may also move the mouse or use the arrow
   keys for this if you prefer.

   2.2 Commands

   Commands tell EDDY what to do to the files that are displayed.  Generally,
   they affect the current file, as selected by the cursor.

   The most common commands are assigned to function keys.  Other commands
   generally are assigned to an [Alt+letter] combination.

   2.2.1 Hot Keys

   All of EDDY's functions may be called upon by using the corresponding "hot
   keys".  The following (VERY incomplete!) summary is provided simply to
   suggest how easy it is to use some of EDDY's most common commands.

   Further details of use of the various keys and key combinations may be
   found in the later sections of this document.  A complete list of command
   key assignments is given in Appendix B.

   Some common commands used in "EDIT" mode are:

   [F1]: HELP
   [F2]: UNDO changes on this file
   [F3]: LOOK at data in file, LOOK at files in directory, or LOOK at disk
   [F4]: PATCH data in file or on disk
   [F5]: COPY file
   [F6]: MOVE file
   [F7]: DELETE file
   [F9]: Exit to DOS temporarily (DOS shell)
   [F10]: QUIT, return to original default directory

   [Alt+d]: Sort files by DATE/time           [Alt+n]: Sort files by NAME
   [Alt+e]: Sort files by EXTENSION           [Alt+s]: Sort files by SIZE
                        [Alt+i]: INVERT display sequence

   [Alt+f]: FIND string in file
   [Alt+o]: inquire/change OPTIONS
   [Alt+t]: inquire/change/create TARGET directory
   [Alt+w]: change WORKING directory/file selection
   [Alt+x]: eXCHANGE working & target directories

   Many command keys may also be used together with the [Ctrl] key.  [Ctrl]
   (indicated in this document by "^") means "do the command for all files".
   E.g., [^F5] means copy all files, and [^F2] means undo all changes on all
   files.  (Option /L -- Section 2.3 -- changes the effect of the "^".)

   To interrupt one of the [^Fn] commands, press [^c] or [BackSpace].  Any
   files tagged for copy, delete, etc. up to that point will stay tagged, but
   no further action will take place.  If you just want to pause temporarily,
   to look at the screen or think about what's going on, press and hold
   [Scroll].  All processing will stop.  Release the key to continue.

   2.2.2 Pull-Down Menus - [Alt+F1]

   Press [Alt+F1] and a pull-down menu panel is displayed, as well as a menu
   bar across the top of the screen, with other menu topics to choose from.

   The menu panel lists commands which may be executed by EDDY.  To the right
   of each command a "hot key" is shown.  This key may be used to execute the
   command directly from EDDY, without using the menu.  To select a command
   from the menu, you may:

       1) press the highlighted letter for that command; or
       2) move the cursor to the command and press [Enter] (or left click
              your mouse); or
       3) press the indicated "hot key" for the command (unless the hot
              key is shown enclosed by "< >", in which case the hot key cannot
              be used from the menu).

   Some lines on some panels show "(sub-menu)" instead of a hot key.  If you
   choose one of these, another panel will be displayed, with commands
   relating to the subject you chose.  These commands may be selected in the
   same 3 ways described above.

   If you don't want to choose a command, press [Esc] (or right click mouse).

   To view the data in the display that has been covered by a menu panel,
   press [PgUp].  This allows you to look at the display (except the top line,
   which is covered by the menu bar) without exiting from the menu.  To pull
   down a menu panel, press the highlighted letter for the topic, or press
   [Enter] (or left click) to pull down the panel for the
   currently-highlighted topic.

   A list of other topics available is displayed across the top of the screen.
   The topics are those which pertain to the type of display you are working
   with.  For example, in EDIT mode, you won't see topics that relate to LOOK
   or PATCH modes.  To view the panels for the other topics shown at the top
   of the screen, press [Left] or [Right] (or move the mouse).

   In EDIT mode, the choice of topics also depends on the line your cursor is
   currently on.  If it's on a file, you'll get a choice of commands that are
   valid for files; if it's on a directory or disk line, you'll get choices
   that are valid for those lines.

   Similarly, in LOOK mode, some commands are valid only if the display is in
   ASCII (text) format, and some only with hex format.  Also, different
   commands are available when LOOKing at a file, disk or RAM.  The choices
   you'll see in the menus depend on what you're doing.

   EDDY v.7c User's Manual   Copyright (C) 1987-93 by John Scofield  page  12



   The first time a particular menu bar is loaded at the top of the screen,
   EDDY makes a guess as to which panel from that menu bar you'll most likely
   want to use, and displays that panel.  On later calls which use that same
   menu bar, the menu panel displayed will be the last one you used.

   EDDY loads the MENU module from EDDY.AUX when you press [Alt+F1], if enough
   memory is available (around 24K).

   The first time you ask for the menu, it will take a little longer than
   subsequent requests, as the disk must be read.  The MENU module then stays
   resident unless the DOS Gateway is used.

   The menus and HELP screens have their own color attributes, not tied to
   those used for other EDDY screens (but menu colors are the same as HELP
   colors).  These colors may be customized as desired (See Section 25.2).

   2.2.3 Dialog Boxes

   Some commands need more information in order to accomplish their functions.
   For example, [Alt+Shift+t] is used to select a new target directory; press-
   ing it displays a dialog box asking you to enter the required path.

   For these boxes, just type the required information, and press [Enter] when
   you are finished.  EDDY will use the new information according to the type
   of command involved.  If you make a mistake, or decide not to continue,
   press [Esc] and whatever you have typed will be discarded.

   Dialog boxes are used with these commands:
        [Alt+t]/[Alt+Shift+t]:  inquire/change/create TARGET directory
        [Alt+v]:  change/create VOLUME label
        [Alt+w]/[Alt+Shift+w]:  change WORKING directory/file selection
        [^w]:  "Where's That File?" search for WORKING directory
        [Shift+F9]:  point-n-shoot

   They may also appear as the result of some other commands, such as [F5] -
   COPY file -- when no target directory has been given.

   When a dialog box is displayed, the area into which you may type data is
   highlighted in reverse video (or underline, with monochrome monitors).
   Text entry may be done in either "insert" mode, in which each keystroke
   entered pushes everything right one character, or "replace" mode, in which
   each keystroke overlays the character at the cursor.  You may toggle
   between insert and replace modes by pressing [Ins].  If you are in insert
   mode, a "right arrow" will appear directly below the cursor.  When the
   dialog box is first displayed, replace mode is in effect.

   If there is an initial string displayed, such as a path, you may edit it as
   desired, and press [Enter] when the result is ready for use.

   If the first key you press after the initial display is a character (i.e.,
   not a cursor control key) in the first (leftmost) position, the initial
   string will be erased, allowing a completely new string to be entered.  In
   addition, [^End] will always erase from the cursor to the end of line.

   If you want to redisplay the initial string after it has been erased, or
   after you have modified it, move the cursor to the leftmost position and
   press [Home].

   NOTE: The dialog boxes associated with the commands...

        [Alt+f]: FIND string in file
        [Alt+r]: FIND and REPLACE string in file

   do not follow these rules.  Refer to Section 16.1 for more information.

   2.2.4 List Boxes

   These boxes present a list of items for which state values may be selected
   (e.g., "ON/OFF", "YES/NO/MAYBE").  List boxes are used with these commands:

        [Alt+a]: file attribute filter selection
        [Alt+c]: inquire/change controls for Copy & Move
        [Alt+o]: inquire/change options

   To set values for an item in the list, move the highlighted cursor bar to
   the item and click the left mouse button or press [Tab].  When all values
   are set correctly, move the cursor to the "OK/Cancel" line, ensure the "OK"
   box is highlighted, and left click or press [Enter].  The highlight can be
   moved between "OK" and "Cancel" by pressing [Left] or [Right].

   If you click on this line or [Enter] while "Cancel" is highlighted, all
   changes will be discarded.  Changes may be discarded at any time by right
   clicking or pressing [Esc] -- from any line.

   To restore settings to the values they had when EDDY started executing --
   the default values, possibly modified by settings made from the command
   line -- press [*] or left click on the "*" line.

   EDDY v.7c User's Manual   Copyright (C) 1987-93 by John Scofield  page  15



   2.3 Options - [Alt+o]

   Options tell EDDY which of two possible courses of action you want used in
   various situations.  For example, you may choose option settings to
   determine:  1) if and how a file's "archive" attribute should be changed
   when the file is copied; 2) whether to interpret characters typed in the
   filename field as changes to the filename or as a signal to search for a
   matching filename; 3) whether to use color in the display or not.

   Options may be set either ON or OFF, with corresponding meanings described
   below.  Options (unless EDDY has been otherwise customized, as described in
   Section 24) are initially set to OFF.

   You may change option settings (except /U and /W) by pressing [Alt+o].  A
   list box will appear.  Pressing any of the option letters toggles the
   option setting between ON and OFF.  Or move the cursor to an option and
   click the left mouse button or press [Tab].  When the settings are the way
   you want them, press [Enter].  Pressing [*] resets the options to the
   values they had when EDDY started:  i.e., the default values, as modified
   by any options you used on the command line (see Section 3.2).

   Options which may be set from the list box are designated by letters.  In
   addition to those options, there are certain options which may only be
   specified from the command line.  These are designated by numbers.  The
   available letter options are:

   /A - Do not change the file archive (modify) attribute when copying or
   moving files.  Default (option /A OFF) action depends on the drives used...
     - Floppy to floppy: copy's attributes set same as original
     - Hard disk to hard disk: copy's attributes set same as original
     - Floppy to hard disk: copy's archive attribute OFF, original unchanged
     - Hard disk to floppy: copy's archive attribute ON, original OFF
     - Remote (network) drives: attributes never changed

   /B - Turn off the "beep" that normally sounds for errors or warnings.

   /C - Do not change the cursor size.  Default is to use a larger cursor in
   EDIT mode, a full-height cursor in PATCH mode, and set it to a two-pixel
   high underline at exit.  If you start EDDY with this option OFF, and then
   turn it on, EDDY will not reset the cursor at exit.

   With /E and /C both ON, /C has no effect - i.e., the cursor will be changed

   /D - Include directory sizes in the display.  Disk space used by subdirec-
   tories is normally not included in the EDIT mode display.  With option /D
   ON, all such space will be accounted for.  However, gathering the infor-
   mation is VERY time-consuming, particularly on lower-speed hardware, so you
   may wish to use it only if it is really important to you.

   Option /D has no effect on remote (network) drives.

   EDDY v.7c User's Manual   Copyright (C) 1987-93 by John Scofield  page  16


   /E - Set EGA or VGA monitor to use "extra-line" text display mode (43 or 50
   lines).  If the monitor is already in extra-line mode when EDDY starts, the
   option display window -- [Alt+o] -- will show /E is ON.  If you change /E
   while in EDDY, the display mode will change immediately.  If you were also
   using option /C, that option is turned OFF when /E changes

   /F - Turn on filename editing (i.e., renaming).  When /F is ON, files may
   be renamed by typing the new filename over the old.  If /F is OFF, typing
   in the filename field causes a "speed search" for a file with a matching
   name.  See Section 4.1 for more on this.

   With option /F turned OFF, pressing [Ins] in EDIT mode turns renaming ON
   for that file only, until the cursor moves to another line.  When option /F
   is ON (file renaming enabled), a "." appears between the filename and
   extension fields.  If it is ON for only the current file (i.e., you pressed
   [Ins]), then only that file's display has the ".".

   /H - Files with "hidden" or "system" attributes are not mormally displayed
   unless they are explicitly requested by use of attribute filtering -- and
   with filtering, ONLY files with those attributes will be shown.  To include
   these files by default, together with all other files, use option /H.

   /K - Some error and status messages are displayed briefly (about 3 seconds)
   and then disappear.  If you would rather have the messages remain until you
   press a key (any key), use this option.  In this case, if the key you press
   is one of EDDY's command keys, the command will be executed.

   /L - List control.  Changes the scope of the [Ctrl]-shifted commands.
   Normally, these commands affect all files listed, starting from the top of
   the display (i.e., the first file).  If you want EDDY to start from the
   current cursor position (ignoring files higher up in the list), use /L.

   /M - Monochrome monitor.  Useful with mono monitor + Color Graphics
   Adapter, and with some laptops' screens.  Other equipment combinations do
   not need this option, although it will toggle between color and mono
   displays on any color monitor.

   /R - RAM Editing.  With this option turned ON, EDDY treats the PC's memory
   as a file, which you may LOOK at, FIND strings in, PATCH or COPY.

   /U - Use minimum memory.  Default is to expand to 170K, if there is that
   much available.  A maximum of 96K will be used if this option is turned on.
   Using this option means that fewer files can be accommodated (currently,
   around 115), and a smaller I/O buffer will be used, which means slower
   copying and moving...UNLESS you have LIM/EMS expanded memory.  Expanded
   memory will be used if available, and the buffers will be full size.

   /W - Set "Where's That File?" searching; move to next directory that has a
   file which matches the current file spec and any timestamp and/or attribute
   filter used.  Search from current directory downward in the directory tree.
   This option can be set by the user ONLY from the DOS command line.  It is
   set internally by EDDY when the [^w] command is used.

   3. EDDY's DOS Command Line

   When EDDY is executed without any options, paths or filenames given on the
   DOS command line, the current default drive and directory path are used.

   The command line format is:

   EDDY [/option...] [work] [target] [+attribute...] ["timestamp"]

   (The brackets -- "[" and "]" -- are not part of the format, and should not
   be typed on the command line)

   All parameters are optional.  The last two parameters, "attribute" and
   "timestamp", are for use in selecting files to be displayed by criteria
   other than paths and filenames with wildcards.  Full explanations of these
   are given in Section 17.

   If you enter a command line in the wrong format, the format description
   line (above) will be displayed, with an arrow under the parameter in error.


   3.1 Path Specifications

   On the command line, [work] defines the working directory, in normal DOS
   format, just as used with the DIR command (d:\path\filename.ext).  Wild
   card characters are supported.  If no filename is given, *.* is assumed.
   Paths may be specified using either "\" or "/", as you prefer.  Similarly,
   ";" is treated as ":", on the assumption that you forgot to [Shift].

   [target] defines the target directory, to receive any files copied or
   moved.  No filenames are allowed in the [target] specification.

   For example, "EDDY .  c:" would display all files in the current default
   directory, and any files copied or moved would go to the current directory
   of drive "c:".

   If you enter an unambiguous filename -- i.e., no wildcards -- EDDY will go
   straight into LOOK mode for that file.  When you exit LOOK, the working
   directory will be "*.*".  (After going to LOOK in this way, you may notice
   that your disk's "busy" light comes on for a bit.  Not to worry!  EDDY is
   using the time between keystrokes to build the "*.*" display, to be ready
   when you exit from LOOK.)

   For example, "EDDY c:\testdir\abc" would display all files in subdirectory
   "\abc" or, if there is no such subdirectory, display the contents of file
   "abc" in the "testdir" subdirectory.

   Working and target directories may be changed during execution, as
   explained in Section 5.

   EDDY v.7c User's Manual   Copyright (C) 1987-93 by John Scofield  page  18



   3.2 Options on the Command Line

   Options may also be given to EDDY on the DOS command line, as with normal
   DOS commands, -- e.g., "EDDY/A/K" tells EDDY to use options "A" and "K".
   Options, if any, must be first, before any path or other specifications.

   If your version of DOS supports "switch" characters other than "/" for
   command line parameters (options), EDDY will accept whatever character you
   use with your system (e.g., "-" is preferred by some users).

   Details of the options are presented in Section 2.3.  In addition to those
   options, which are known by their "letter" designators, there are certain
   parameters which may be specified from the command line.  These options are
   designated by numbers.  They allow specification of settings that are not
   the normal defaults for the way you use EDDY, or for batch operations (see
   Section 20).  The numeric options are:

   /0 -
        Execute in "customize" mode, to create a copy of EDDY with various
        features tailored to your preference.  See Section 25.

   /1x -
        Override the normal startup display sequence.  "x" must be one of the
        sort sequence codes defined in Section 1.4.2.  If "x" is a capital
        letter, the sequence will be in ascending order; if lowercase, in
        descending order.

   /2xxxxxx -
        Override the normal COPY/MOVE/DELETE Control settings, as described in
        Section 10.  From 1 to 6 "x"s may be used.  Each "x" must be "c", "y"
        or "n" except "c" is invalid for the sixth one.  Either case is O.K.

   /5, /6, /7, /8 -
        These options correspond to keys [^F5], [^F6], [^F7] and [Shift+^F7]
        (COPY, MOVE, DELETE and DESTROY all files).  Only one of these options
        may be used at a time.  When any of these are used, the corresponding
        command is carried out in batch mode.


   EDDY v.7c User's Manual   Copyright (C) 1987-93 by John Scofield  page  19


   /9nn -
        EDDY determines the number of lines per screen from a byte in memory
        that is set by the PC BIOS.  Some BIOSes apparently don't maintain
        this byte correctly for some monitors.  If this seems to be your
        situation (i.e., EDDY doesn't use all the lines your screen can
        handle), try using /9, with "nn" set to a number from 25 through 66.

        Using a number greater than the monitor can handle has unpredictable
        results.  This option should not be used with EGA or VGA monitors.
        Screen height is adjusted with these monitors by using Option /E.


   3.3 Other Command Line Parameters

   Two other parameters may be entered on the command line:  an "attribute
   filter" specification and/or a "timestamp filter" specification.  These
   specifications are used to select files for display based on their file
   attributes -- hidden, directory, etc.  -- or date and time.  They are
   explained in detail in Sections 17.1.1 and 17.2.1, respectively.


   4.  Editing Directory Entries

   To select a file for editing, move the cursor to the line of the display
   for that file.  The line with the cursor will be highlighted, and the
   corresponding file becomes the "current file".  Editing is then done by
   simply typing the new information over the old on the screen.

   The cursor will skip over fields which can't be edited, such as file size.
   If you try to enter data which is not valid (e.g., letters in a date or
   time field), EDDY will "beep" at you and ignore the entry.

   It is possible to enter combinations of characters which result in invalid
   data in a field.  For example, "02" is a valid month and "31" is a valid
   day, but together they are an invalid date.  EDDY catches errors of this
   type whenever you try to move the cursor off of the current file.  EDDY
   "beeps" and puts the cursor on the field where the error was detected.

   When any editing has been done, an "*" will appear at the right end of the
   line to indicate that changes have been made to that file.


   4.1 Selecting a File or Directory (Speed Search)

   There are two ways to move the cursor to the file (or directory) entry you
   are interested in:  by using the cursor keys ([Up], [Down], etc.), or
   directly, by using the "speed search" feature (with option /F turned OFF).

   With the cursor on the filename, typing any character that's valid for a
   filename tells EDDY to move the cursor to the next entry in the display
   with a name that matches.  Matching is done from the first character of the
   current filename up to and including the character just typed.

   EDDY v.7c User's Manual   Copyright (C) 1987-93 by John Scofield  page  20



   For example, consider the display shown in Figure 1-1 (Section 1.3).  If
   you were positioned on the "WOMBAT" entry, with the cursor on the "W", and
   you pressed [e], the cursor would move to the "EDDY" directory entry, with
   the cursor on the first "D".  If you then pressed [r], the cursor would
   move to the "ERROUT.ASM" filename, on the second "R".

   If you press [Shift] and type a letter, that letter will always be matched
   against the FIRST letter of the file or directory name, regardless of which
   byte of the name the cursor is currently positioned on.

   Refer again to Figure 1-1.  Suppose you were positioned at the top of the
   file list, and held down [Shift] while pressing [e] three times in a row.
   The cursor would move first to the "EDDY" directory entry, then to the
   "ERROUT.ASM" filename, and finally to the "ERROUT.OBJ" filename.

   Speed search is disabled when option /F is ON.

   Speed search is also available for choosing directories from the directory
   tree display, as described in Section 5.3.2.


   4.2 Renaming Files

   Turn on option /F (explained in Section 2.3) if you want to rename files.
   If this method is used, direct file selection, as described above, is
   disabled; typing over the filename field renames the file.

   To rename a file without disabling direct file selection, first press
   [Ins].  This turns on /F only while the cursor remains on the current line;
   as soon as it moves to a new line, /F is reset.

   To rename a file, type the new name over the old on the screen.  A "*" will
   appear to the right of the extension, to remind you that a change has been
   made.  The file will be renamed on disk when you enter UPDATE mode.

   Any valid characters for filenames may be entered, including spaces (except
   the first character may not be a space).  Valid characters are any in the
   range 20h through 7Eh, except for the following:
                          [ . " / \ :  | < > + = ; , ]

   Lower case letters are converted to upper case by DOS.  You can rename
   files with EDDY so that they can't be used with normal DOS commands, by
   using names containing embedded blanks.

   When you rename a file, it will be moved to its proper place in the
   display, according to the sort sequence then in effect.

   If you try to rename a file so that it is the same as an existing file or
   subdirectory in your working directory, EDDY will "beep" and put the
   cursor in the filename field.

   EDDY v.7c User's Manual   Copyright (C) 1987-93 by John Scofield  page  21



   4.3 Changing Date and Time

   Dates are displayed in mmddyy, ddmmyy, or yymmdd format, depending on the
   use of DOS's "COUNTRY.SYS; times are displayed based on a 12-hour clock
   with an "a" or "p" to show a.m. or p.m.

   Only valid month/day/year combinations may be entered.  Hours in the range
   01 to 12 are accepted; minutes and seconds must be less than 60.  Seconds
   may be set only to even numbers -- a DOS limitation.  (Except:  You can set
   the date and time to all zeros.  If you do this, the timestamp will not be
   displayed at all when you use the DOS "DIR" command.  Useful to call
   attention to entries in "DIR" listing).

   EDDY uses its own timestamp.  EDDY's timestamp is either the current DOS
   date and time, or a date and time which has been set by pressing
   [Alt+equal].  Pressing [Alt+equal] freezes EDDY's timestamp at the date and
   time of the current file or directory until changed by another [Alt+equal].

   Pressing [=] puts EDDY's timestamp on the file if [Alt+equal] has been
   pressed previously; if not, the current DOS date and time is used.

   [Alt+minus] undoes the effect of a previous [Alt+equal].

   When a change has been made to the date or time, an asterisk will appear in
   the line to the right of the field changed.


   4.4 Changing File Attributes

   Attribute bit settings are displayed under the heading "RHYDAS", indicating
          R)EAD-ONLY, H)IDDEN, SY)STEM, D)IRECTORY, A)RCHIVE and S)HARED
   file attributes, respectively.

   A "y" indicates the attribute is on for this file; "n" means it is off.

   The attribute bit settings may be changed by typing the new value over the
   old, except the "directory" and "shared" attributes can't be changed.

   When you type "y" or "n" in an attribute field, the cursor moves right, to
   the next attribute that can be changed.  This can be annoying if what you
   want is to change attributes on a series of files (e.g., removing read-only
   attributes).  So, a second way of changing the attributes is provided:
   press [+] to toggle the attribute ON/OFF (y/n) without moving the cursor.

   When a change has been made to an attribute bit, that attribute will be
   displayed as a capital letter instead of the normal, lower case display.

   You can also change an attribute for all files in the working directory
   with a single command.  Move the cursor to the column of the attribute you
   want to change (the line the cursor is on doesn't matter unless option /L
   is ON) and press [^y] or [^n].

   5.  Moving to a New Directory

   You can change EDDY's working directory and/or target directory at any
   time. These may be on the same or different disks.


   5.1 Dialog Boxes or Tree Diagrams -- Your Choice

   You have a choice of selecting directories from a graphical tree diagram or
   by text entry, using a dialog box.  The tree diagram is generally easier to
   use, but the dialog box is needed in certain situations, described below.
   Also, there is a delay associated with the tree diagram the first time a
   disk is accessed (or each time, on a floppy).

   The dialog box entry method is needed if you want to change the file
   specification used to select files for inclusion in the working directory
   display (e.g., you want to use "*.CPP" rather than "*.*").  It is also
   needed if you want to create a new directory for use as the target.

   5.1.1 How to Choose

   To choose a new working or target directory, press [Alt+w] or [Alt+t],
   respectively.  [Alt+w] and [Alt+t] work identically, except for the
   directory they work with.  For the remainder of this section (5.1.1), any
   reference to [Alt+w] and working directory also applies to [Alt+t] and
   target directory.

   The first time you press [Alt+w], you'll see the dialog box for entry of a
   new working directory.  Press [Alt+w] while this box is displayed, and EDDY
   will switch to the tree diagram for working directory selection.

   Once you have requested the tree diagram, it will be considered your first
   choice for working directory selection.  Anytime you press [Alt+w] from the
   EDIT mode display, you will see the tree display, not the dialog box.

   If you want to switch your choice back to the dialog box, press [Alt+w]
   while the tree diagram is displayed.

   [Alt+w] may be toggled in this way as often as you wish.  If you customize
   your copy of EDDY (see Section 24), the default action for [Alt+w] will be
   set to the action (tree or box) in effect when you customize.

   You may also choose to use the dialog box anytime you want, regardless of
   the action setting for [Alt+w]; if you press [Shift] at the same time --
   i.e., [Alt+Shift+w] -- the dialog box will always be displayed.  This does
   not affect the action setting for [Alt+w].

   REMEMBER: All references to [Alt+w] also apply to [Alt+t].

   5.1.2 Performance Considerations

   When EDDY scans a drive to determine the tree structure, you may save the
   scanned data in a file for later use (by pressing [F5]).  This has the
   advantage of faster display creation, but may be inaccurate if you have
   made changes to the directory structure since the file was created.

   a. Memory is Always Up-to-Date

   EDDY maintains the tree structure information for up to two drives in
   memory.  If a third drive's tree is requested, one of the memory areas will
   be reused, and any later access to the previous drive's tree will incur the
   initial delay again.

   If a tree data memory area is needed to be reused, an area associated with
   a floppy drive will be selected if possible.  This minimizes extra delays,
   as the tree data for floppy disks is refreshed with every reference anyway.

   If you use the DOS Gateway or Point-n-Shoot functions, EDDY has no way of
   knowing what changes may have been made.  Therefore, the tree information
   will be refreshed the next time the tree diagram is requested, and so
   you'll experience the delay again in this case, too.  Also, if you change
   the tree by creating new (target) directories, or by renaming, moving or
   deleting directories, the tree information must be refreshed.

   The maximum number of directories which EDDY can handle for one disk drive
   is difficult to specify, as it depends on how long the directory names are
   -- shorter names take less space.  However, if your drive has all 12-byte
   directory names (ffffffff.eee), 480 of them can be accommodated.

   The tree data may also be overwritten if you call on functions that need
   more memory, and the only way to get it is to use the memory where the tree
   data is stored.  Functions that MAY produce this condition are:  LOOK,
   UPDATE, HELP, and MENUs.

   EDDY v.7c User's Manual   Copyright (C) 1987-93 by John Scofield  page  24



   b. Save a Tree - [F5]

   If you have directories that don't change very often, you may want to save
   the tree data in a file.  Then, on subsequent tree displays, the data from
   the file will be used, saving the normal scanning delay.

   Press [F5] while the tree diagram is displayed to save the data.  It will
   be saved in a file called "EDDYTREE.{x}", where "x" is the drive ID letter.
   This file will be stored in the root directory of the drive involved.  If
   you press [F5] again later, the file will be overwritten by the new data.

   When you request the tree diagram, the data from EDDYTREE.{x} will always
   be used to create the display if the file exists (and has not been
   corrupted).  If the display is built from the file, you'll see
   "EDDYTREE.{x}" at the lower left corner of the screen; if it's not there,
   the diagram was built by scanning the tree structure.

   If you suspect that the tree data from the file might be out-of-date, you
   may refresh the display (a new tree structure scan) by pressing [^x], where
   "x" is the drive ID letter of the currently-displayed drive.

   Note that refreshing the displayed tree by pressing [^x] does NOT update
   the tree data file automatically.  Except when EDDY finds an
   already-existing, but out-of-date version of EDDYTREE.{x}, the file is
   updated only when you request it explicitly, by pressing [F5].

   If EDDY finds that the tree file is out-of-date (e.g., tree file doesn't
   include the current directory), it will be rebuilt, and automatically
   updated on your disk.  Since the file was on your disk already, EDDY
   assumes you still want it.


   5.2 Directory Selection via Dialog Box

   To request the dialog box for entering working or target directories, press
   [Alt+Shift+w] or [Alt+Shift+t], respectively.

   You may specify the full path including drive and/or root, or a partial
   path that EDDY will interpret relative to the current working or target
   directory, as appropriate.  If your entry includes a drive and root (e.g.,
   "C:\WORK"), EDDY will use the specification exactly as you enter it.

   If you enter only a drive (e.g., "C:"), the default directory for that
   drive will become the new (working or target) directory.  If the current
   default is not the root, it will be displayed before it is used.

   When typing a path, you may use [Ins] and [Del] to make changes to it.

   EDDY v.7c User's Manual   Copyright (C) 1987-93 by John Scofield  page  25



   5.2.1 Working Directory Dialog Box - [Alt+Shift+w] / [Alt+w]

   The working directory may be changed by pressing [Alt+Shift+w] (or [Alt+w],
   if that key is set to request the dialog box) and entering the new path,
   according to the rules described in the preceding paragraph.

   A file specification may also be entered, either with or without a path.
   If you enter only a file specification (e.g., "*.BAT"), that file
   specification will be used with the current working directory.

   EDDY tries to use your specification as a path.  If no such path can be
   found, what you have entered is used as a file specification.

   If you start the name with a "\", EDDY interprets this as a directory path
   starting from the root of the current working directory's drive.  If
   there's no initial "\", EDDY appends the name you provide to the end of the
   current working directory path string, and uses that as the new directory.

   For example:  suppose your current working directory is C:\UTIL and the DOS
   default on drive D:  is D:\WORK.  After pressing [Alt+w], if you type...
          "\" or ".." the new working directory will be C:\
          "\FOO" the new   working directory will be C:\FOO
          "FOO" (or "C:FOO") the new working directory will be C:\UTIL\FOO
          "D:" the new working directory will be D:\WORK
          "D:FOO" the new working directory will be D:\WORK\FOO

   Also see Section 5.7 if you work with "SUBST"ed drives.

   If you change your working directory to the same as your target directory,
   the target directory specification in EDDY will be set to "no target".  If
   you then enter a COPY or MOVE command, EDDY will ask you for a new target.

   For other ways to change directories, see Sections 5.4 (Exchange Working &
   Target Directories), 5.6 (Where's That File?) and 8.1 (LOOK at Directory).

   5.2.2 Target Directory Dialog Box - [Alt+Shift+t] / [Alt+t]

   The target directory may be changed by pressing [Alt+Shift+t] (or [Alt+t],
   if that key is set to request the dialog box).  EDDY will display the
   current drive and path (or tell you that there is no current target) and
   allow you to change the target directory if you wish.

   If you don't want to enter a new target directory after pressing
   [Alt+Shift+t], press [Esc].  The target directory will remain unchanged.

   No file specification may be used in the target directory path
   specification; only a drive and path are allowed.  The target directory
   cannot be set the same as the working directory.

   Partial path specifications are interpreted exactly as described above, for
   working directories, if there is no current target.  If there is a target,
   partial paths are interpreted relative to it.

   If you start the name with a "\", EDDY interprets this as a directory path
   starting from the root of the current target directory's drive.  If there's
   no initial "\", EDDY appends the name you provide to the end of the current
   target directory path string, and uses that as the new directory.

   For example:  suppose your current target directory is C:\TGT and the DOS
   default on drive D:  is D:\EASY.  Then, after pressing [Alt+Shift+t], if
   you type...  "\" or ".." the new target directory will be C:\ "\MONEY" the
   new target directory will be C:\MONEY "MONEY" (or "C:MONEY") the new target
   directory will be C:\TGT\MONEY "D:" the new target directory will be
   D:\EASY "D:MONEY" the new target directory will be D:\EASY\MONEY .

   If you enter a target directory name that doesn't exist after pressing
   [Alt+Shift+t] or [Alt+x], EDDY will normally ask if you want to create a
   new directory.  However, if any parts of the path preceding the name of the
   directory are also invalid, you will just get an error message.

   5.3 Directory Selection from Tree Diagram

   To request the tree diagram for the working directory's drive, press
   [Alt+w]; for the target directory's drive, [Alt+t].  If you get the dialog
   box display, press [Alt+w] or [Alt+t], respectively, again.

   5.3.1 Tree Display Format

   In the tree diagram, four types of directories are distinguished:

        - The current DOS default directory is shown in "braces", like {THIS}.

        - The working directory is shown enclosed in the special "double
          angle-brackets" characters, and looks something like <<THIS>>.

        - The target directory has solid triangle characters pointing to it on
          either side.  These characters are unprintable on many printers, and
          are not shown here.  They will be obvious in the display.

        - Other directories have no special characters enclosing them.

   The working/target directory will be highlighted when the tree is
   displayed.  To select a new directory, move the highlight to it and press
   [Enter] (or left-click the mouse).

   5.3.2 Moving the Tree Highlight (Speed Search)

   The highlight may be moved with the mouse, the cursor keys, or by using the
   "speed search" feature.

   The mouse and cursor keys work generally as you'd expect.  However, note
   that a [Right] arrow or mouse move always moves to the next directory in
   the tree.  Repetitions of [Right] will eventually visit every directory in
   the tree -- a complete "tree walk".  When the highlight is on the last
   directory in the tree, another [Right] will wrap back to the root.

   A [Left] arrow or mouse move goes to the parent of the currently
   highlighted directory.  Repeated [Left]s will quickly return to the root.

   You may also move the highlight by pressing keys corresponding to the
   directory name you want to select.  This is the speed search feature.
   Speed search works the same way it does for directory displays in EDIT
   mode, as described in Section 4.1.  (Except that option /F has no effect).

   A cursor within the highlight shows where the next character typed will be
   placed (just as in EDIT mode).  This cursor is not moved by using the
   cursor keys; they move the highlight, as described above.  The cursor moves
   right one column for each character typed.  Press [BackSpace] to move left.

   After positioning the highlight, press [Enter] to select a directory as the
   new work or target.  Alternatively, press [Alt+F10].  [Alt+F10] tells EDDY
   to terminate, leaving the selected drive/directory as the new DOS default.

   EDDY v.7c User's Manual   Copyright (C) 1987-93 by John Scofield  page  28



   5.3.3 Moving to a New Drive - [^letter] / [^\]

   If you press [^\], you'll get a list of valid drives to choose from.
   Either press a letter from the list, or move the cursor to the desired
   drive letter and then [Enter] or left-click.  [^\] may be used in from EDIT
   mode, or while the dialog box is displayed, or from the tree diagram.

   While the tree diagram is displayed, diagrams for other drives may be
   displayed by pressing [Ctrl] and the drive letter identifier; e.g., to get
   the tree display for drive C:, press [^c].

   You may also go directly to the tree diagram for any valid drive from the
   dialog box.  If you press [^letter] while the working directory dialog box
   is on-screen, the action is just as though you had pressed [Alt+w],
   followed immediately by [^letter].  That is, you'll get the tree display
   for the drive, and any subsequent use of [Alt+w] from EDIT mode will yield
   the tree display rather than the dialog box.  [^letter] pressed while the
   target directory dialog box is on-screen works similarly.

   5.3.4 Working Directory Tree - [Alt+w]

   With the tree diagram displayed, move the highlight to the desired
   directory name and press [Enter] (or left-click).  The highlighted
   directory will become the new working directory.

   If you change your working directory to the same as your target directory,
   the target directory specification in EDDY will be set to "no target".  If
   you then enter a COPY or MOVE command, EDDY will ask you for a new target.

   When you display the tree diagram for the working directory's drive, you
   will not see the current DOS default directory enclosed in "{ }".  This is
   because the current directory is always the same as the working directory
   while EDDY is in control.

   If you display the tree for another drive (e.g., by pressing [^c]) you will
   see the current directory on that drive.  If the working directory is on a
   SUBST'ed drive which is part of the new drive's tree structure, both the
   {CURRENT} and <<WORKING>> directories will be indicated.

   5.3.5 Target Directory Tree - [Alt+t]

   With the tree diagram displayed, move the highlight to the desired
   directory name and press [Enter] (or left-click).  The highlighted
   directory will become the new target directory.

   You may not select a target directory the same as the working directory.

   If you press [Alt+t] with no target directory previously selected, the tree
   diagram for the working directory will be displayed.

   EDDY v.7c User's Manual   Copyright (C) 1987-93 by John Scofield  page  29



   5.4 Exchange Working & Target Directories - [Alt+x]

   To exchange the current working and target directories, press [Alt+x] (This
   turns off option /W if it is on -- see Section 5.6).  When you exchange,
   EDDY will "remember" your current file, and will return the cursor to that
   file if you later exchange back (with no intervening changes of directory).

   5.5 Directory Recall - [Shift+F10], [Shift+^F10]

   Directory recall may be set for the current working directory by pressing
   [Shift+F10].  This directory may later be "recalled" as the working
   directory by pressing [Shift+^F10].  See Section 15.1 for more information
   on using directory recall.

   5.6 Where's That File?  - Option /W and [^w]

   To find the directory (or directories) a file is in, use option /W from the
   command line and/or the [^w] command within EDDY.

   For example, enter:  EDDY/W C:\FOO*.* to search drive "C:" for any
   directory that has a filename beginning with "FOO" in it, with any
   extension.  If a directory is found that contains such a file, that
   directory will be set as the working directory.  Press [^w] to find the
   next such directory, if any.

   If you enter:  EDDY/W ">06/15/91", EDDY will search the directory tree
   starting from the current directory, and will stop when a file is found
   that was created after the indicated date (see "Filtering by Timestamp").

   From the command line, using option /W causes EDDY to search the disk for
   matching files, starting with the given working directory and continuing
   downward in the directory tree.  The directories are searched in "unsorted"
   sequence; i.e., the order they actually are stored on your disk.  The
   working directory which will be displayed is the first one found which has
   matching files.  If there is no match, you'll get "File not found".

   Pressing [^w] when option /W is off turns /W on, and EDDY then searches
   from the current directory downward in the tree for a directory with one or
   more files matching the current file, attribute and/or timestamp
   specifications.  If found, that directory becomes the new working
   directory.  If there are no matches, you'll get "File not found", and /W
   will be turned off.

   Pressing [^w] when option /W is on causes EDDY to search the directory tree
   for the next directory, relative to the directory which was current when
   you first pressed [^w], which contains matching files.  Using [^w] again
   will display the next directory, if any, which has matching files.

   Explicitly changing working directory (by using [F3], [Alt+w],
   [Alt+Shift+w] or [Alt+x]) will turn off option /W.

   5.7 Working With "SUBST"ed Directories

   EDDY can switch freely between SUBST'ed drives and subdirectories and their
   un-SUBST'ed, fully expanded path equivalents.

   5.7.1 From the Command Line

   Suppose your current DOS default drive is actually SUBST'ed, and you are in
   the highest level directory of that SUBST'ed drive (i.e., what is
   effectively the "root" directory for that drive).  In this case, if you
   specify either the working or target directory as "..", the true drive and
   path will be used.

   For example, if you earlier used the DOS command "SUBST X:  C:\FOO\BAR" and
   your current default drive is "X:", using ".." will be interpreted by EDDY
   as "C:\FOO".  If your current default is "X:\WORK", EDDY would inter- pret
   ".." the same way DOS does -- i.e., "X:\".

   5.7.2 Interactively

   Once EDDY is executing, if you change directories as described in Sections
   5.1 - 5.4, or by using [F3] as described in Section 8.1, you have even more
   flexibility with SUBST'ed drives.

   Using ".." works the same as it does on the command line, as described in
   the preceding section.

   However, "." used from within EDDY is interpreted as the un-SUBST'ed, fully
   expanded path string.  Thus, using the example in the preceding section, if
   your current working directory is "X:\WORK" and you use ".", EDDY will
   interpret this as "C:\FOO\BAR\WORK".

   This is only a change in the way the directory is referenced; it is the
   same physical directory no matter which string is used to refer to it.
   Therefore, the display of files, bytes used, etc., will not be affected.

   EDDY v.7c User's Manual   Copyright (C) 1987-93 by John Scofield  page  31


   6.  HELP When You Need It - [F1]

   When you have a choice to make as to how you want EDDY to proceed, you can
   get relevant HELP information by pressing [F1].  The HELP screen you get
   will be different, depending on what you were doing when you pressed [F1].

   Once you are in HELP mode, you may view other HELP screens.  Pressing [F1]
   while in HELP displays the menu of available topics.  You may select from
   the menu, or press [PgUp] or [PgDn] to view the screens sequentially.

   For the HELP function to operate, EDDY must be able to find the file
   "EDDY.AUX".  EDDY can find it in any of the following directories:

   - A directory which is mentioned in your DOS PATH statement
   - The current working directory
   - The directory you executed EDDY from (if you have DOS 3.0 or higher)

   The initial HELP display, which appears when you type just "EDDY" with
   nothing else on the command line, is disabled when you use a customized
   copy of EDDY (see Section 24).  However, if EDDY finds he's running a
   customized copy on a machine that appears to be different from the one
   where the customizing was done, the initial HELP is re-enabled.

   EDDY loads the HELP module from EDDY.AUX when you press [F1], if there is
   enough memory available (around 50K).

   The HELP screens and menus have their own color attributes, not tied to
   those used for other EDDY screens (but HELP colors are the same as menu
   colors).  These colors may be customized as desired (See Section 25.2).

   6.1 HELP for Warnings and Other Messages

   Most of EDDY's messages can readily be understood from their wording and
   context.  For those that seem worthy of a bit more explanation, however,
   Appendix C of this document offers further information.  When there is more
   information provided there, a message to that effect will appear beneath
   the warning or error message.


   7.  UNDO Command - [F2], [^F2]

   Any changes requested may be "Undone" as long as they have not yet been
   written to disk by entering UPDATE mode.  To undo changes on the current
   file, press [F2].  To undo all changes for all files, press [^F2].

   7.1 Partial UNDO

   You may UNDO the COPY, MOVE, DELETE and DESTROY commands without affecting
   other changes pending for the file.  Just press the key for the same
   command again; i.e., if a file is tagged for COPY, and you decide not to
   COPY, press [F5] and the tag will disappear, but other changes will remain.

   EDDY v.7c User's Manual   Copyright (C) 1987-93 by John Scofield  page  32



   8.  LOOK Command - [F3], [^F3]

   LOOK has three variations, depending upon where the cursor is.  If the
   current line has a subdirectory, the request is interpreted as "display the
   contents of this subdirectory".  For normal files, LOOK means "display the
   contents of this file".  If the "Drive X:  is..." heading line is under the
   cursor, LOOK means "treat the entire disk as a file, and display it".


   8.1 LOOK at Subdirectory

   When you LOOK at a subdirectory, you change EDDY's working directory.  To
   do this, move the cursor to the display line of the directory you want to
   LOOK at and press [F3].  Changing directories with [F3] turns off option /W
   if it is on. For other ways to change the working directory, see Section 5.

   Figure 8-1 might have been reached from the display in Figure 1-1, as
   follows:  1) turn on option /R, to get " memory" in the display; 2) move
   cursor to the subdirectory "EDDY", and press [F3]; 3) in the resulting
   display (not shown), move cursor to "MACROS" line and press [F3] again.

   EDDY v.7c User's Manual   Copyright (C) 1987-93 by John Scofield  page  33



   Using [F3] to change directories turns off option /W if it is on.

   If you move to a new working directory with changes pending (renames,
   copies, etc., which have not been through an UPDATE), the changes will be
   discarded -- in effect, Undone.  If there are pending changes, EDDY will
   warn you and ask for confirmation before moving to the new directory.

   Also see Section 5.7 if you work with "SUBST"ed drives.

   If there are no changes pending, pressing [Enter] will have the same effect
   as pressing [F3] if you are positioned on a file, directory or "drive"
   entry in the display; i.e., you will LOOK at that entry.  On other display
   lines, you'll get the usual "Nothing to update" message.  [Enter] always
   initiates an UPDATE if changes are pending, or if you are customizing EDDY.

   Note that the third box on the right side of the screen shows "LOOK" as the
   action corresponding to [Enter] if there are no changes pending; if there
   are, the box says "UPDATE".

   If you don't like the use of [Enter] as an alternate way to LOOK, see
   Section 25.3.4.

   8.2 LOOK at File Contents (in Working Directory)

   To LOOK at the data contained in the current file, press [F3].  [^F3] LOOKs
   at the data in ALL files in the directory, one at a time.  Pressing [Esc],
   or pressing [F3] a second time, returns you to EDIT mode.

   8.2.1 LOOK Mode Commands

   a. Hex/ASCII Format Control - [Tab], [Shift+Tab]

   EDDY uses the first 512 bytes in a file to decide how to display the data
   (hex or ASCII format).  ASCII is used if at least 80% of the first 512
   bytes are printable (20h - 7Eh), formatting control characters -- CR, LF,
   FF, TAB -- or line/box-drawing characters.  Otherwise, hex format is used.

   [Tab] toggles between ASCII and hex display formats.  If you don't like
   that key, press [Shift+Tab].  EDDY will ask you to press the key you want
   to use as a toggle.  Any function key or [Alt]-shifted key that doesn't
   conflict with other LOOK, PATCH or FIND usage is OK.  E.g., [F5] and [F12]
   are OK, but [F1] (the "HELP" key) is not; [Alt+h] is OK, but [Alt+b] (used
   for bit-stripping) isn't.  If [Tab] is not used to toggle, it may be used
   in PATCH and FIND to enter TAB characters.  (See Sections 9 and 17).

   b. Printing a File - [Alt+p]

   Pressing [Alt+p] prints the current file.  Printing begins with the line at
   the top of the screen, and continues until a key is pressed.  With a
   non-ASCII file, it's probably a good idea to ensure it's "printable", by
   pressing [p] before [Alt+p].  See Section 8.2.5a for more on this.

   Pressing [Alt+Shift+p] sends a formfeed to the printer, but doesn't print.

   c. EGA/VGA Screen Control - [e]

   If you have an EGA (or VGA) monitor, you may switch between 25 lines per
   screen and 43 (or 50) lines by pressing [e].  This is the same as turning
   option /E ON or OFF (see Section 2.3).

   8.2.2 ASCII Format Display

   In ASCII format, a new line is initiated when either a CR or LF is
   encountered (but a CRLF pair only counts as one line).  The line number of
   the line at the top of the screen is shown on the status line at the bottom
   of the screen.  The highest line number EDDY can display is 65535.

   The "arrow" (and related) keys work a little differently in LOOK mode.  The
   display may be thought of as a "window" which can be moved around to view
   various parts of a file, while the file itself does not move.

   The keys used to move the display window around in ASCII format are:

    [Up]        - move up 1 line         [Down]   - move down 1 line
    [PgUp]      - move up 1 page         [PgDn]   - down 1 page
    [^Home]     - first page             [^End]   - last page
    [Left]      - left 1 column          [Right]  - right 1 column
    [Shift+t] ([T]) - tab left 20 columns  [t]    - tab right 20 columns
    [^Left]     - left edge (col. 1)     [^Right] - right edge (last column)
    [Home]      - same as [^Left]        [End]    - same as [^Right]
    [^PgDn]     - auto-scroll down       [^PgUp]  - auto-scroll up

   [PgUp] and [PgDn] move a screen at a time, overlapping the previous screen
   by one line.  When paging in ASCII format through a long non-text file,
   EDDY may spend a lot of time looking for CRs and LFs that aren't there.  If
   EDDY appears to be "hung up" after a [PgUp] or [PgDn], press [^c] or
   [BackSpace] to interrupt the processing and display the file from wherever
   EDDY has reached, and no further processing will take place.

   If you just want to pause temporarily, to look at the screen or think about
   what's going on, press and hold [Scroll].  All processing will stop.
   Release the key to continue.  s read to thus far.

   The effect of the [Up] and [Down] keys in LOOK mode may be modified by
   pressing [s].  [s] toggles these keys between their normal scrolling speed
   of one-line-per-keypress and half-page-per-keypress ("speed scrolling").  A
   half page is defined by the number of text lines in the display, not the
   physical lines available on your screen.  Thus, the speed of scrolling will
   vary, depending on the data you're LOOKing at.

   Speed scrolling is of limited value unless you're using a mouse.  With a
   mouse, it gives a faster way of scrolling, without requiring use of the
   keyboard to press [PgUp]/[PgDn].

   Auto-scroll moves the display up or down continuously, without further key
   presses.  It is started by [^PgDn] or [^PgUp].  Pressing the same key again
   speeds up the scrolling; pressing the opposite one slows it down.  Any
   other key stops auto-scroll.

   8.2.3 ASCII Format Commands

   a.  TAB Expansion - [0] thru [8] / [Alt+0] thru [Alt+8]

   TABs expand to 8-character boundaries as a default.  You may change the TAB
   expansion by pressing [0], [1],...,[8].  TABs will then expand to the
   boundary you have selected.  If you press [0], TAB characters will be shown
   as "blobs" on the screen, and no expansion will be done.

   The default setting is used with each new entry to LOOK.  You can change
   the default setting by pressing [Alt+0], [Alt+1],...,[Alt+8].

   The current TAB expansion factor is shown at the bottom of the screen.  If
   this is also the default, it will be indicated by an "=" (e.g., "tab=8");
   if it is a temporary setting, a ":" will be used (e.g., "tab:4").


   b.  Bit Stripping - [b] / [Alt+b]

   With files that have lots of high-order bits set (e.g., WordStar) to
   obscure the real meanings of the characters, try bit-stripping.  Pressing
   [b] causes EDDY to clear the high-order bit before the characters are
   displayed.  Press [b] again to toggle the bit-stripping action.

   Bit-stripping is normally OFF when you enter LOOK mode, and "bits=8" will
   be shown on the bottom line.  The "=" means the displayed value is the
   default, which will be reset at each entry to LOOK.  If you press [b], you
   will see the display "bits:7".  This means that only the low-order 7 bits
   are used from each byte for building the display, and the ":" indicates
   that this is a temporary state, in effect only until you exit LOOK mode.

   To change the default state for bit-stripping, press [Alt+b].

   If you use [b] (or [Alt+b]) after the first line of the file, EDDY loses
   track of the line number.  To indicate this, the bottom line shows
   "line:?".  Returning to the top of the file restores the line number
   synchronization.

   EDDY v.7c User's Manual   Copyright (C) 1987-93 by John Scofield  page  37



   c.  Ruler Line Display - [r] / [u] / [d]

   To determine what position a particular character in the display occupies
   in its line, press [r].  You will see a line similar to this one:

   21 ++++++^+++++++++^+++++++++^+++++++++^+++++++++^+++++++++^+++++++++^+++++

   The number at the left is the column number in the file of the character
   shown in column 1 of the screen.  The "^" characters mark the columns which
   are even multiples of 10 in the FILE (not necessarily the same as columns
   on the screen).  In this example, which is what you might see after a [t],
   the "^"s mark columns 30, 40, etc.

   The ruler is moved up or down by pressing [u] or [d], respectively.


   d.  Jump to New Line - [j]

   You may move directly to any line in the file by pressing [j], and then
   typing the line number you are interested in.  If you type a number larger
   than any in the file, you'll get a display of the last few lines.

   After pressing [j], you'll see a field of 5 zeros, where you may enter the
   line number to which you want to jump.  The cursor starts in the second
   digit of this field, on the assumption that line numbers entered will most
   frequently be 9999 or less.  However, you may use all 5 positions if
   needed.  Line numbers larger than 65,535 are not supported.


   e.  Line Wrapping - [l] / [Alt+l]

   Line wrapping means all lines are "broken" if they are longer than 80
   characters, with the remainder appearing on the next line of the screen.
   Thus, the whole line is visible on the screen at once.

   [l] is a toggle key which turns line wrapping alternately ON and OFF.  Line
   wrapping normally defaults to OFF on entering LOOK mode.  In this case, you
   would see the string "line=1" at the bottom of the display, which tells you
   that line wrapping is OFF (the first character is "l"), this is the default
   state for the toggle (the "=" sign) and we are at the first line of the
   file.  If you press [l] to turn line wrapping ON, a broken vertical line
   (the DOS "piping" symbol) replaces the "l" in "line", and the string
   displayed would be "|ine:1".  The ":" shows that ON is a temporary state.

   To change the default state for line-wrapping, press [Alt+l].

   EDDY v.7c User's Manual   Copyright (C) 1987-93 by John Scofield  page  38



   Even though the lines are wrapped on the screen, EDDY still works with
   complete logical lines, as determined by the presence of CR/LF characters.
   When you move the display up or down, a line at a time or by paging, the
   display moves in units of complete logical lines.  The display will always
   begin at the start of a logical line (except in some cases when toggling
   between ASCII and hex formats).  Movement of the display up or down is
   based on the line at the top of the screen.


   8.2.4 Hex Format Display

   An example of a hex format display appears below (Figure 8-2).  The number
   under the heading "Offset" is the number of bytes from the start of the
   file, in hex.  Next comes the hex value of the data, followed by the
   equivalent characters, under the "ASCII" heading.

   8.2.5 Hex Format Commands

   The keys used in LOOK mode to move around in the hex-format display are:

    [Up]    - move up 1 line          [PgUp]  - up 1 page
    [Down]  - move down 1 line        [PgDn]  - down 1 page
    [^Home] - display first page      [^End]  - display last page
    [^PgDn] - auto-scroll down        [^PgUp] - auto-scroll up

   Additional commands are available in hex format are described below.


   a.  Printability - [p]

   Normally, the characters under the "ASCII" heading are the exact
   equivalents of the hex data.  However, many of the characters corresponding
   to the hex values in the ranges 00h -- 1Fh and 7Fh -- 9Fh are interpreted
   as printer commands by most printers.  An attempt to use the DOS
   [Shift]-[PrtSc] function on a screen containing these characters will
   result in an assortment of form feeds, font changes, carriage returns,
   etc., rather than the screen print desired.

   EDDY provides an option to accommodate screen printing of hex displays.  If
   you press [p], telling EDDY to format the screen for printing, the
   characters in the troublesome ranges will be replaced by periods, and all
   high-order bits will be turned off.  The hex data part of the display is
   unchanged.  When [p] is pressed, a blinking letter "P" appears at the right
   end of line 1 to remind you that "printability" is turned on.  [p] is a
   toggle key, and turns printability alternately on and off.

   The example in Figure 8-2 has printability selected.


   b.  Bit Stripping - [b] / [Alt+b]

   Bit stripping in hex format works as described in 8.2.3b, above, but
   affects only the ASCII portion of the display.  The actual character
   present in the file, with no bits stripped, is shown in the hex portion of
   the display.

   c.  Jump to New File Position - [j]

   You may move directly to any position in the file by pressing [j] and then
   typing the 8-digit hex offset which you are interested in.  If you type too
   large a value, you'll get a display of the last few lines of the file.

   If you jump with the display in hex format, EDDY loses track of the line
   number (but you get there faster).

   EDDY v.7c User's Manual   Copyright (C) 1987-93 by John Scofield  page  40



   d.  Word-oriented Display - [w], [W]

   When LOOKing at a file in hex format, you may select the hex portion of the
   display to be in words (as opposed to the normal bytes) by pressing [w].
   If you want to see the words in inverted order (high-order byte first),
   press [W].  Press the same key again to return to the normal byte display.

   If you want the word display to start with the odd-numbered bytes, press
   [t].  Press [t] again to revert to even byte orientation.

   When displaying inverted words, the heading at the top of the display shows
   the inverted sequence of bytes.


   8.2.6 LOOK Mode With a Mouse

   In LOOK mode, ASCII (text) display format, a left click from anywhere calls
   up the menu.  In hex format, the otherwise unused area between the two
   parts of the display is indicated by arrows pointing from the bottom line;
   left click here to call the menu.

   When PATCHing, a left click anywhere except the indicated "click area"
   means "update" (same as [Enter]); a double left click means "update, don't
   change timestamp" (same as [^Enter]).

   A right click returns to EDIT from LOOK, or to LOOK from PATCH.


   8.3 LOOK at File Contents (in Target Directory) - [Alt+F3]

   If there is a file in the target directory with the same name as the
   current file, the contents may be LOOKed at by pressing [Alt+F3].  If there
   is no target directory, or there is no file with that name, you will be
   informed.  Otherwise, you will see a display identical to that described
   above, and all the LOOK mode commands will work the same way.

   When the file displayed is from the target directory, a "T" is shown on the
   last line in column 7, thus:

   8.4 Compare Directory Entries - [Shift+F3], [Shift+^F3]

   To compare the directory entries of corresponding files in the working and
   target directories, press [Shift+F3].

   Press [Ctrl], [Shift] and [F3] simultaneously to compare working and target
   directory entries (one at a time) of all files in the working directory.
   After each comparison, the result is displayed and EDDY waits for a key to
   be pressed before proceeding to the next comparison.

   [^c] or [BackSpace] terminates a [Shift+^F3].


   8.5 Compare Files - [Alt+Shift+F3]

   Press [Alt], [Shift] and [F3] simultaneously to compare the contents of the
   current file with those of the corresponding file (i.e., same filename) in
   the target directory.  The files may be in any format.

   EDDY will tell you whether the file contents are identical or not.  The
   offset in the file where bytes do not match (if any) will be displayed,
   along with the hex values of the bytes involved.

   If the files are different lengths, the comparison will still be done.
   This allows you to determine, for example, whether the files are identical
   at least up to the length of the shorter one.

   Successive [Alt+Shift+F3]'s on the same file tell you the next byte where a
   difference exists.  If there are no more differences, EDDY will tell you
   that.  (On files of different lengths, if the only difference is the extra
   bytes in the longer one, only the first difference will be reported.)


   8.6 LOOK at RAM (or ROM, or ???)

   You may LOOK at your PC's memory (if option /R is ON) by moving to the "
   memory" entry and then pressing [F3].  RAM contents will be displayed in
   hex format, from 0000:0000 up to the limit of installed RAM.  EDDY bases
   its assumption about RAM size on the value in memory at 0040:0013 -
   0040:0014h at the time EDDY begins executing.  If your system has 640K, for
   example, you will see "80 02" in these locations.

   EDDY refreshes the display between keystrokes, so you can watch various
   locations in RAM as they change; e.g., the BIOS timer count at 0040:006Ch,
   the diskette motor counter at 0040:0040h, or the keyboard buffer and
   related data starting at 0040:0017h.  (Not true for Color Graphics Adapters
   -- too much screen "flicker".  See Section 25.3.3 if you have a CGA)

   It's sometimes interesting to look at other parts of the PC address space,
   such as ROMs and display memory.  For example, if you press [j] and then
   enter an offset of "F000:FFFF", you will see the end of the BIOS ROM, which
   usually has the copyright notice.

   EDDY v.7c User's Manual   Copyright (C) 1987-93 by John Scofield  page  42


   One curiosity:  When accessing addresses that have no physical memory
   equivalent, EDDY will show hex "FF" for those bytes; however, bytes with
   other values sometimes appear.  If you try to go back to display those
   bytes after they have scrolled off the screen, they may have changed value
   or even have disappeared.  This does not appear to be a bug in EDDY.  This
   also occurs with DEBUG and Turbo Debugger when they are used to look at
   high memory.


   8.7 LOOK at Entire Disk

   You may also LOOK at an entire physical disk, regardless of file locations
   or extents.  This is explained in detail in Section 21.1.


   9.  PATCH Command - [F4], [^F4]

   Normally, you will use LOOK or FIND before PATCH, in order to locate the
   place in the file to PATCH.  Once you have found it, press [F4].  If you
   want to PATCH every file in the directory (one at a time), press [^F4].

   Pressing [Esc], or pressing [F4] a second time, returns you to LOOK mode.

   The PATCH mode display is similar to the LOOK mode hex format display with
   "printability" turned off.  It has two cursors -- one in the hex part of
   the display and one in the ASCII part.  These cursors move in unison, to
   facilitate matching corresponding bytes in the two parts of the display.

   One of the cursors will be blinking, the other not.  The blinking cursor
   shows where you may enter changes to the data.  [Tab] toggles between hex
   and ASCII data entry formats.  (If you don't like [Tab] for this purpose,
   see Section 8.2.1).  If [Tab] is not the toggle key, it can be used to
   enter TAB -- 09h -- bytes directly in ASCII format).

   In ASCII data entry format, the cursor in the text part of the display
   blinks and the hex cursor does not.  The hex cursor also expands to cover
   two hex digits, since entering a single text character affects both digits.

   In either format, as you enter data in one part of the display the
   corresponding data in the other part is updated and displayed accordingly.
   Also, any data changed remains highlighted (reverse video) in the display.

   You can move the cursors to the place you want to change data with the
   "arrow" keys -- [Left], [Right], [Up] and [Down] -- and [Home] and [End].

   If you go to PATCH right after a FIND, the blinking cursor will be on the
   character at the start of the "found" string.  The cursor will be in the
   same mode (hex/ASCII) used to enter the search string when you did the
   FIND.  If you press any key except [F4] after the FIND, the cursor will be
   placed on the first character of the display if you then PATCH.

   Changes can be made to only one screen at a time.  To UNDO, press [F2].

   9.1 Changing a File's Length

   You may use [Alt+z] to add bytes at the end of a file, or [Alt+y] to delete
   bytes, either from the beginning or end of the file.

   9.1.1 Appending Bytes to a File - [Alt+z]

   Files may also be expanded using PATCH.  With the cursor at the end of the
   file, with unused space left on the screen, you can add a "^Z" (end-of-file
   byte) after the last byte in the file by pressing [Alt+z].  You can add as
   many bytes as you want, up to the limit of space on the screen (or until
   the disk is full).  Bytes that have been added can also be patched.

   9.1.2 Deleting Bytes From a File - [Alt+y]/[Alt+a]/[Alt+b]

   After a press of [Alt+y], EDDY asks whether you want to delete bytes BEFORE
   or AFTER the cursor, and then waits for [b] or [a], respectively.  You may
   also press [Esc], if you decide not to delete anything after all.

   Pressing [b] deletes from the beginning of the file up to the byte at the
   cursor.  [a] deletes everything in the file after the byte at the cursor.
   The byte at the cursor is never deleted.  If you press [b] with the cursor
   on the first byte of the file, or [a] while it's on the last, EDDY won't
   complain, but nothing will be deleted.

   Pressing [Alt+a] is equivalent to [Alt+y] followed by [a], with no question
   asked.  [Alt+b] is equivalent to [Alt+y], then [b].


   9.2 Updating in PATCH - [Enter] or [^Enter]

   You may write your changes to disk by pressing [Enter] twice.  Normally --
   after [Enter] -- EDDY puts the current DOS date and time on a file that has
   been patched.  If you use [^Enter] to start the UPDATE, EDDY asks whether
   you want to do this.  (If you have customized EDDY as described in Section
   24, no question is asked, and the timestamp remains unchanged.)

   After UPDATE, EDDY will return to LOOK mode.  In LOOK mode you may move to
   another part of the file, and then press [F4] to go back to PATCH to make
   more changes.  The PATCH-UPDATE-LOOK-PATCH cycle may be repeated as needed.


   9.3 PATCHing RAM

   With option /R turned ON, you may change your PC's memory by using PATCH on
   the " memory" entry in the display.

   One thing that is almost SURE to hang up your machine is to mess with the
   values in the BIOS keyboard buffer pointers (0040:001A - 0040:001D), so
   EDDY will not allow these locations to be updated.  EDDY won't complain if
   you TRY to change them, and they'll appear to be changed right after
   patching, but they'll really still be set to the values DOS has put there.

   9.4 PATCHing Disks by Physical Sector

   You may also PATCH any bytes on a physical disk, regardless of file
   locations or extents.  This is explained in detail in Section 21.2.

   WARNING!  DO NOT USE SECTOR PATCHING ON "COMPRESSED" OR "EXTENDED" DRIVES
   -- I.E., DEVICES CREATED AND MANAGED BY STACKER, DOUBLEDISK, SUPERSTOR, AND
   SIMILAR PRODUCTS.  PATCHING FILES STORED ON THOSE DISKS IS PERFECTLY SAFE,
   HOWEVER.  SEE SECTION 21.6 FOR MORE INFORMATION.

   10. COPY/MOVE/DELETE Controls - [Alt+c]

   These Controls affect operation of the COPY, MOVE, DELETE and DESTROY
   commands, which are described in Sections 11 through 13.

   When copying, moving or deleting files, you'll often want to choose the
   files to be operated on based upon whether they are in the target directory
   or not, and also based on a comparison of their timestamps.  Common cases
   are when you'd like to give commands such as:

      "Copy files that are newer than the corresponding files in the target"
   or
            "Delete files that are duplicates of those in the target".

   The COPY/MOVE/DELETE Controls allow you to just that, as well as many other
   combinations.  There is a Control for each of the following cases:
            1. File not in target
            2. Target file older
            3. Target file NEWER!
            4. Target different size (date and time same)
            5. Same date,time & size
   These Controls are always checked when a COPY or MOVE command is used.
   There is also a sixth Control, which determines whether the first 5 will be
   used with DELETE and DESTROY commands, too:
            6. CONTROLS for Delete?

   Controls 1-5 may each have a setting of "Y" (Yes, tag the file if this
   statement is true), "N" (No, don't tag the file if this statement is true)
   or "C" (Confirm before tagging).  "C" does not apply to Control #6.

   "Y" and "N" provide a way of selecting files to be affected by multiple-
   file commands -- e.g., COPY all files ([^F5]).  They are NOT used with and
   have NO EFFECT on single-file commands -- e.g., COPY this file ([F5]).

   A Control setting of "C" means whenever that case is encountered, the
   target directory entry will be displayed.  EDDY then waits for you to
   confirm whether you want to tag the file or not.  "C" controls operation of
   both single- and multiple-file commands.

   The default Control settings (1 - 6) are Y,Y,C,C,N,N.  The settings may be
   displayed and/or changed by pressing [Alt+c].  You may then select the
   values for the Controls by pressing [y], [n], or [c], or by pressing [Left]
   or [Right].  Pressing [*] restores default settings.

   EDDY v.7c User's Manual   Copyright (C) 1987-93 by John Scofield  page  45



   For the first example given at the beginning of this section -- "Copy files
   that are newer...", the Control settings would be N,Y,C,C,N,N.  For the
   second example -- "Delete files that are duplicates...", the settings would
   be N,N,N,N,Y,Y (or N,C,C,C,Y,Y if you want to be told about differences).

   There is one case where the "File not in target" control will be ignored.
   If you COPY or MOVE when there is no target directory, one of the actions
   you may take is to create a new directory to serve as the target (see
   Section 5.2).  If you have just created the target, then obviously any file
   you want to copy will be "not in target".  In this case, Control #1 will be
   treated as "Y" as long as the target directory remains the same.

   EDDY v.7c User's Manual   Copyright (C) 1987-93 by John Scofield  page  46



   11.  COPY Command - [F5], [^F5]

   Press [F5] to copy the current file.  If there is no target directory, EDDY
   will ask for one.  Entering target directories is explained in Section 5.2.

   The word "Copy" will appear, to show the file has been tagged.  The actual
   copy will be done when you enter UPDATE mode.  After the copy, "copied"
   will appear in the display for that file.

   If you have other changes to be made to the directory entry (renaming,
   timestamping or attribute settings), these changes will be made before the
   copying, so the target copy will have the same settings as the working copy
   after the update.

   An exception to this is the archive attribute bit.  Files copied will have
   the archive attribute turned ON in the target directory (unless you are
   using option /A, or the target is on a remote disk).  For files copied from
   a fixed disk (or RAM disk) to a floppy, the archive attribute is also set
   OFF in the working directory.  In all other cases, the archive attribute is
   left unchanged in the working directory.

   If a file with the "shared" attribute is copied, the result in the target
   will not have that attribute.

   Copied files normally receive the same date and time as the original; if
   you want to put the current timestamp on copies, use [^Enter] to start the
   UPDATE process, rather than [Enter].  If you use [^Enter], EDDY will ask
   you whether or not you want new timestamps.

   [^F5] will review all files in the working directory for copying, except
   those already tagged for COPY, MOVE, DELETE or DESTROY.  All files which
   meet the criteria defined by the COPY/MOVE/DELETE Controls (see Section 10)
   will be tagged for copying when you enter UPDATE mode.  [^c] or [BackSpace]
   interrupts EDDY after [^F5], and before all files have been reviewed.

   If you just want to pause temporarily, to look at the screen or think about
   what's going on, press and hold [Scroll].  All processing will stop.
   Release the key to continue.

   Changing the target while files are selected for copying or moving will
   result in these files being deselected.  EDDY will warn you if this occurs.

   Using option /5 on the command line is the batch mode equivalent of [^F5].
   See Section 20 for more information on this.

   EDDY v.7c User's Manual   Copyright (C) 1987-93 by John Scofield  page  47



   11.1 COPY/MOVE/DELETE Confirmation

   When EDDY encounters a case with a corresponding Control setting of "C",
   the following message is displayed:

      "[F3]/[Alt+F3]:LOOK,  [F5]:COPY,  [F6]:MOVE,  [F7]:DELETE,  else [Esc]"

   [F3] puts you into LOOK mode, to examine the file contents in the working
   directory, in case you need more information from the file in order to
   decide what to do.  [Alt+F3] lets you LOOK at the file in the target.  In
   either case, when you exit from LOOK, you will be at the same place in the
   display, with EDDY still waiting for one of the other keys to be pressed.

   [F5], [F6] and [F7] will tag the file for the normal action for that key.
   [Esc] -- or any other key -- will leave the file untagged.

   One situation can be tricky:  if the reason for the display is "Target file
   NEWER!", and you proceed to LOOK mode and from there to PATCH, your
   patching will normally update the file's timestamp.  Upon return, EDDY will
   find that the condition requiring your decision no longer exists, and will
   tag the file for COPY or MOVE automatically.

   In addition to the cases defined by the Controls, some other situations are
   also checked:

   - A MOVE, DELETE or DESTROY  must be confirmed if the file has the "read-
     only" attribute ON.

   - A COPY or MOVE must be confirmed if the corresponding file in the target
     has the "read-only" attribute ON.

   - A COPY or MOVE will not be allowed if the target contains a subdirectory
     with the same name as the file.

   EDDY v.7c User's Manual   Copyright (C) 1987-93 by John Scofield  page  48



   11.2 COPYing Files With Disk Errors

   If you have a file that's on a disk that has "bad spots", EDDY will often
   let you save the "good" parts, by COPYing the file.  See Section 24.4.


   11.3  Alterations to a Copied File

   If you have a WordStar-like file, with lots of high-order bits obscuring
   the text, you can make a readable copy by copying with bit-stripping.  If
   you want to get rid of TAB characters in a file, you can also do that.

   11.3.1  TAB Expansion - [Alt+0] thru [Alt+8]

   To get rid of TABs in a file, tag it by pressing [Alt+number].  [Alt+#]
   (where "#" is "2" thru "8") means expand (at UPDATE time) any TABs in the
   file with spaces to move to the next #-byte boundary, resulting in a larger
   file.  This can possibly cause an out-of-space condition during the UPDATE,
   as explained in Section 24.2.  [Alt+1] replaces each TAB by a single space.
   [Alt+0] deletes the TABs completely, resulting in a smaller file.

   Files which have been tagged in this way will show the TAB expansion used
   in parenthesis after the "Copy"; e.g., if you used [Alt+4], you would see
   "Copy(4)" to the right of that file's display.  If bit-stripping was also
   used, you would see "Copy(b4)".

   As every byte must be scanned individually, TAB expansion is much slower
   than other copying.

   11.3.2  Bit-Stripping - [Alt+b]

   To get rid of the high-order bits that obscure the text in some files, tag
   the file(s) by pressing [Alt+b].  The new copy will have no high-order bits
   in it after the UPDATE is done.

   Files which have been tagged in this way will show "Copy(b)" to the right
   of the file's display.


   11.4 COPYing RAM

   To capture the contents of RAM, use [F5] on the " memory" entry.  The data
   will be dumped into a file named "-MEMORY-.@@@".  If such a file already
   exists, it will be overwritten.  The file will be as large as your PC's
   memory, so on floppy-based systems you may not have enough room.


   11.5 COPYing Disks

   Data may be copied to or from disks without regard to logical file
   structure.  See Section 21.5.

   EDDY v.7c User's Manual   Copyright (C) 1987-93 by John Scofield  page  49



   12.  MOVE Command - [F6], [^F6]

   Moving a file places its entry in the target directory and deletes it from
   the working directory.  This is the same as doing a COPY and then a DELETE.

   Press [F6] to select the current file to be moved.  If there is no target
   directory specified, EDDY will ask for one.

   [^F6] will review all files in the working directory for moving, except
   those already tagged for COPY, MOVE, DELETE or DESTROY.  All files which
   meet the criteria defined by the current settings of the COPY/MOVE/DELETE
   Controls (see Section 10) will be tagged for moving when you UPDATE.  To
   interrupt EDDY after [^F6], press [^c] or [BackSpace].

   If you just want to pause temporarily, to look at the screen or think about
   what's going on, press and hold [Scroll].  All processing will stop.
   Release the key to continue.

   The word "Move" will appear in the display next to a file that has been
   selected.  The actual moving will be done when you enter UPDATE mode.
   After UPDATE, the word "moved" will appear in the display for that file.
   The display of size, date, etc., will be cleared, indicating that the file
   no longer exists in that directory.  If you re-sort the display, or move to
   another working directory and then return, files moved won't be displayed.

   The heading information showing the number of files in the display and the
   number of free bytes on the disk will be updated.

   The archive attribute is always set ON in the moved file's directory entry
   (unless you are using option /A, or the target is on a remote disk), so
   that the file will be backed up the next time a backup is done for the
   target directory.  If the moved file has the "shared" attribute ON, it will
   be turned OFF if the move is to a different disk.

   Using option /6 on the command line is the batch mode equivalent of [^F6].
   See Section 20 for more information on this.


   12.1 Moving Subdirectories

   WARNING!  DO NOT MOVE DIRECTORIES ON "COMPRESSED" OR "EXTENDED" DRIVES --
   I.E., THOSE DEVICES CREATED AND MANAGED BY STACKER, DOUBLEDISK, SUPERSTOR,
   AND SIMILAR PRODUCTS.  SEE SECTION 21.6 FOR MORE INFORMATION.

   This feature is sometimes called "prune and graft".  Subdirectories, and
   any files or other subdirectories contained in them, may be moved if:  1)
   the target directory is on the same disk; 2) the target does not contain a
   file or directory of the same name; 3) the target is not in a path which
   includes the directory to be moved (i.e., you can't move a directory to its
   own child or other subordinate directory); and 4) if the target is the
   root, there must be space available in the root directory.

   EDDY v.7c User's Manual   Copyright (C) 1987-93 by John Scofield  page  50



   After a directory move, you may notice a lot of disk activity before the
   EDIT display reappears.  Don't be alarmed; the program is simply rereading
   all the information in both the working and target directories, to ensure
   that all the data displayed reflects the new tree structure.

   This process has been exhaustively tested by the author and many users,
   without any problems.  However, some of us are hesitant (read
   "intelligent") about using programs that mess with our disks in
   non-standard ways.  Therefore, the following information is offered.

   Moving subdirectories cannot be done using the standard DOS application
   services, except by copying each file and subordinate subdirectory
   individually.  EDDY handles this task by writing directly to the working
   and target directories, and using DOS services where available.  No direct
   manipulation of the File Allocation Table (FAT) is involved.

   Specifically, the steps involved in a subdirectory move are:

   1.  Set the "directory" attribute OFF in the subdirectory's entry in the
          working directory.  This makes DOS think the subdirectory is a file.
   2.  Move the "file" to the target directory, with DOS's "rename" command.
   3.  Turn the "directory" attribute back ON in the target directory.
   4.  Adjust the "cluster number" in the moved directory's ".." (parent)
          entry to point to the target rather than the working directory.


   12.2 Had a Problem?  Don't Panic!

   If there is a problem with any of the above steps (e.g., a power failure
   during the update), recovery is straightforward.

   - If the subdirectory is still shown as a directory entry in the working
   directory, there's no problem.

   - If you have reason to suspect there might have been a problem, and the
   entry is shown in the target as a directory, it's possible that step 4 was
   not completed successfully.  This is resolved quickly and easily by running
   "CHKDSK /F" on the disk.  CHKDSK will display "Invalid sub-directory entry"
   and fix the cluster number automatically.

   - If there was a problem with step 3, the subdirectory will be shown as a
   "file" (i.e., no "directory" attribute) in the target, with a length of
   zero.  Don't panic!  There's only one little bit that has to be changed.
   To fix this problem, LOOK at the target, then LOOK at the disk to display
   the raw directory data.  Move the display until the entry for the "file" is
   at the top, and PATCH offset 0Bh to "10h".  Your directory is now restored.
   Exit from LOOK, and you'll see the result.

   - If the subdirectory is shown as a "file" in the working directory, LOOK
   at the disk, and proceed as described in the previous paragraph.

   EDDY v.7c User's Manual   Copyright (C) 1987-93 by John Scofield  page  51


   13.  DELETE Command - [F7], [^F7]

   To select the current file for deletion, press [F7].  No other changes may
   be made to a file that is selected for deletion.

   "Delete" appears next to the file.  The deletion will be done when you
   UPDATE, and "deleted" will appear.  All directory information (size, date,
   etc.) will be blanked out, indicating that the file no longer exists in
   that directory.  If you re-sort the display, files deleted won't be shown.
   The heading information showing the number of files in the display and the
   number of free bytes on the disk will be updated to reflect the deletion.

   If COPY/MOVE/DELETE Control #6 (see Section 10 for more on Controls) is set
   to "N" (the default), [^F7] tags all files in the working directory for
   deletion, except those already tagged for COPY, MOVE or DESTROY.

   If Control #6 is "Y", the other Controls determine which files will be
   tagged by [^F7], based upon a comparison of working and target directories.
   If Control #6 is "Y" and there is no target directory, you'll be asked for
   one.  If you don't enter a target, Control #6 will be treated as "N" for
   processing the current [^F7] command.

   To interrupt EDDY after [^F7], press [^c] or [BackSpace].  If you just want
   to pause temporarily, to look at the screen or think about what's going on,
   press and hold [Scroll].  All processing will stop.  Release the key to
   continue.

   Using option /7 on the command line is the batch mode equivalent of [^F7].
   See Section 20 for more information on this.


   13.1 Deleting Subdirectories

   Subdirectories may also be deleted.

   You may delete subdirectories that still contain files.  EDDY will warn you
   that the directory is not empty when you press [F7], and ask whether you
   want to delete or not.  If you choose to proceed with the deletion, all
   files in the directory, plus any subordinate subdirectories and all of
   their files, will be deleted when you UPDATE.

   In this type of deletion, no check is made for read-only file attributes on
   the files in the subdirectory -- they are all deleted without further
   question.  Obviously, this type of deletion should be done only when you
   are sure there's nothing important left in the directory.

   As the deletions are being made, the full path and file name of each file
   or subdirectory being deleted will be displayed prior to its deletion.  As
   with other UPDATE actions, pressing a key during the UPDATE will suspend
   activity until you decide how you want to proceed.

   EDDY v.7c User's Manual   Copyright (C) 1987-93 by John Scofield  page  52



   13.2 Logical DELETE (Ignore) - [Alt+F7], [Alt+^F7]

   Pressing [Alt+F7] flags a file with "(Ignore)".  It will be ignored by any
   of the repeating (i.e., [Ctrl]-shifted) commands.  This lets you eliminate
   files from a list that you want to do a repeated FIND on, for example, so
   as not to waste time with files that are not of interest for the FIND.
   [Alt+F7] also undoes any changes that may be pending on the file.

   Pressing a key for any command which affects the current file when that
   file is logically deleted cancels the "(Ignore)".  Moving the cursor left
   or right on the line also cancels the "(Ignore)".

   [Alt+^F7] flags all files with "(Ignore)".  This is useful to ignore all
   but a few of the files displayed when executing the next command, such as a
   multi-file FIND -- [^f] -- or multi-file Point-and-Shoot -- [Shift+^F9].
   It's easier to "ignore all" and then UNDO the few, rather than ignoring one
   by one.


   13.3 DESTROY - [Shift+F7], [Shift+^F7]

   To select the current file for destruction, press [Shift+F7].  Destroying
   means to overwrite a file, thus destroying the data in it, and then delete
   the file from the working directory.

   "Destroy" appears next to the file.  The actual overwrite and deletion will
   be done when you enter UPDATE mode.  EDDY overwrites the file with question
   marks.  Afterward, "destroyed" appears next to that file, and all directory
   information is erased.  The counts of the numbers of files in the display
   and the free bytes on the disk will be updated to reflect the deletion.

   If COPY/MOVE/DELETE Control #6 (see Section 10 for more on Controls) is
   set to "N" (the default), [Shift+^F7] tags all files in the working
   directory for deletion, except those already tagged for COPY, MOVE or
   DELETE.

   If Control #6 is set to "Y", then the other Controls are used to determine
   which files will be tagged by [Shift+^F7], based upon a comparison of
   working and target directory entries.  If Control #6 is "Y" and there is no
   target directory, you'll be asked for one.  If you don't enter a target,
   Control #6 will be treated as "N" for processing the current [Shift+^F7]
   command.

   To interrupt EDDY after [Shift+^F7], press [^c] or [BackSpace].  If you
   just want to pause temporarily, to look at the screen or think about what's
   going on, press and hold [Scroll].  All processing will stop.  Release the
   key to continue.

   Using option /8 on the command line is the batch mode equivalent of
   [Shift+^F7].  See Section 20 for more information on this.

   14.0 DOS Gateway

   EDDY allows you to exit to DOS (the DOS "shell"), execute other commands or
   programs, and return to EDDY to pick up where you left off.  All requested
   changes and actions will still be in effect when you return.

   When you exit to DOS, all memory used by HELP and/or by menus is released
   for use by DOS.  In addition, if you are using the gateway from EDIT mode
   (as opposed to LOOK), any memory used by LOOK as well as the i/o buffer
   space will be released.  This memory will be reallocated as required when
   you return control to EDDY.


   14.1 The DOS Shell - [F9]

   From EDIT or LOOK mode, pressing [F9] exits to DOS.  EDDY will ask you to
   confirm that you want to exit.  When you exit, EDDY loads a new copy of
   COMMAND.COM, which will process your DOS commands normally.  The screen is
   cleared, followed by COMMAND.COM's announcement, and then the DOS prompt.

   The default directory will be EDDY's current working directory.  You may
   change this if you wish.  EDDY will restore it when you return.

   When you're ready to return to EDDY, type "EXIT" at the DOS command prompt.

   If you forget to EXIT, you may run short of memory later on, because memory
   remains assigned to both EDDY and the extra copy of COMMAND.COM.  To remind
   you to EXIT, EDDY changes the DOS prompt to end with "Exit>".  (This is not
   done if your DOS environment is larger than 10,529 bytes -- an EDDY
   internal buffer limitation.).  If you don't want this reminder added to
   your prompt, see Section 25.3.1.

   If you use the DOS Shell from LOOK often, you may want to use option /U
   when you execute EDDY.  This leaves more memory for DOS to work with.

   14.2  Point-n-Shoot

   Point-n-Shoot refers to the capability to move the cursor to a file you
   want to operate on ("point") and press a key ("shoot") to begin the
   operation.  EDDY offers three types of point-n-shoot operations:

   - Execute the file (for .COM, .EXE or .BAT files)

   - Operate on the file with any command you choose.

   - Operate on the file with a command you have previously defined in the
     "EDDY.USE" file.


   14.2.1 Execute .COM, .EXE or .BAT File - [Alt+F9]

   When the cursor is located on a file with an extension of "COM", "EXE" or
   "BAT", pressing [Alt+F9] executes that file.

   The filename is first displayed in a dialog box, so that you may edit the
   command line if you like, to add filenames, switches, redirection, or
   whatever is appropriate for the file involved.

   When you are ready to execute the file, press [Enter] (or [Alt+F9] again).

   When the program or batch file finishes, EDDY waits for a key to be
   pressed.  This pause allows time for you to read anything that may have
   been displayed on the screen by the file which was just executed.


   14.2.2 Execute Default Command - [Shift+F8]

   You don't have to guess ahead of time what you might want to do to a file.
   Any command you like may be used on any of your files, at any time.  You
   may even use commands that are not related to a specific file, if you wish,
   although this would normally be done via the DOS Gateway.

   Press [Shift+F8] to get a dialog box showing the current "default" command.
   This command may be used as-is, edited and then used, or replaced entirely
   by whatever command you want to use on the current file.  Press [Enter] (or
   [Shift+F8] again) to execute the command.

   When the default command is used, EDDY always pauses after execution.  This
   pause allows time for you to read anything that may have been displayed on
   the screen by the file which was just executed.

   The commands you enter in the dialog box must include the full path name to
   tell EDDY where the program to be executed is located.

   EDDY v.7c User's Manual   Copyright (C) 1987-93 by John Scofield  page  55


   Also, the program name must be followed by at least one blank, and the
   command, including the filename to be operated on, cannot be longer than 76
   bytes.  Any bytes beyond the 76th will be truncated.

   You may save the new or edited command as the new default if you wish.  If
   you want to make it a permanent default, use EDDY's customizing feature -
   see Section 25.  If you save the command, the name of the current file will
   be replaced in the command for each new file you use it on.

   An un-customized version of EDDY has a default of "C:\DOS\PRINT %".  (The
   "%" means the current filename will be inserted here.) This is included as
   an example only, and may not be suitable for your system.  A comment is
   also included with the sample, as a reminder of the restrictions.

   NOTE:  Don't use the PRINT default if you have not done a "PRINT" before
   you ran EDDY.  PRINT makes part of itself permanently resident the first
   time it is run.  When you finish running EDDY, PRINT's memory will still be
   allocated above where EDDY was located, giving you fragmented memory space.


   14.2.3 Point-n-Shoot with EDDY.USE - [Shift+F9]

   You may define different commands to be used with different files.  For
   instance, you might want to use PKZIP to look at the contents of ".ZIP"
   files, without leaving EDDY.  The files and corresponding commands must be
   defined in a file called "EDDY.USE", which may be created with EDLIN or any
   other editor or word processor which can produce a simple ASCII file.

   A sample EDDY.USE is part of the EDDY distribution package.  This sample
   includes extensive explanatory comments, and I hope it will suggest ways in
   which EDDY can help your system be easier and more convenient to use.

   Files are defined in EDDY.USE as usual for DOS (including wildcards), and
   the commands are similar to .BAT file commands.  The full path must be
   given in the command.  There must be at least one space after the filename.

   EDDY.USE must be in a directory defined in your PATH variable, the current
   directory, or (if you have DOS 3.0 or higher) in the same directory that
   you executed EDDY from.

   EDDY selects a command from EDDY.USE based upon a comparison of the current
   filename and extension with the file definitions at the beginning of the
   lines in EDDY.USE.

   If the current file doesn't match any definition in EDDY.USE -- or if
   EDDY.USE can't be found -- you may will see a dialog box containing the
   default command (see Section 14.2.2, above).

   When you press [Shift+F9], EDDY will display a dialog box with the command
   that is to be executed.  You may press [Shift+F9] again or [Enter] to
   proceed, or you may edit the command before using it.

   EDDY v.7c User's Manual   Copyright (C) 1987-93 by John Scofield  page  56



   For example, if EDDY.USE contains the line:

                           *.ZIP  C:\UTIL\PKZIP -V  %1

   pressing [Shift+F9] with the cursor on EXAMPLE.ZIP will give the display:

                          C:\UTIL\PKZIP -V  EXAMPLE.ZIP

   and pressing [Enter] will list the contents of EXAMPLE.ZIP (assuming, of
   course, that you have PKZIP in the UTIL directory).

   The replaceable parameter ("%1" in the example) tells EDDY where to insert
   the current filename before executing the command.  The "1" in "%1" has no
   significance; any digit may be used, or the "%" used by itself.  It is used
   in the example only to emphasize the similarity to batch files.  Only the
   first occurrence of "%" is used by EDDY.

   Commands from EDDY.USE are displayed and may be edited before they are
   used.  For example, suppose after viewing the contents of EXAMPLE.ZIP as
   described above, you want to extract the THIS.ONE file you found there.
   Just press [Shift+F9] again and edit the command to:

                      C:\UTIL\PKUNZIP  EXAMPLE.ZIP  THIS.ONE

   After executing the command, EDDY normally returns immediately to the EDIT
   directory display.  If you want to pause after the command is executed, use
   a "|" (the DOS piping symbol) as the first character in the command.  With
   the previous example, the command in EDDY.USE would be:

                          | *.ZIP  C:\UTIL\PKZIP  V  %1

   If you edit (modify) the command before executing it, EDDY will always
   pause before returning to the EDIT display.

   EDDY v.7c User's Manual   Copyright (C) 1987-93 by John Scofield  page  57



   14.2.4 Point-n-Shoot Again (and again...) - [Shift+^F8] / [Shift+^F9]

   This facility allows you to repeat the same operation on multiple files, by
   giving a single command to EDDY.  You may use the default command, by
   pressing [Shift+^F8], or a command from EDDY.USE, by pressing [Shift+^F9].

   In either case, the command will be executed first on the current file, and
   then on files below that in the current display.  This is the same effect
   as using option /L has with other repeating ([Ctrl]-shifted) commands.

   With [Shift+^F8], the command will be executed only on files from the
   display that have the SAME extension as the current file.  With [Shift+F9],
   however, if EDDY.USE defines the command for use with any file ("*.*"), it
   will operate on all files.  Any files tagged as "Ignore" will be skipped by
   these commands.

   The commands in the EDDY.USE file for repetitive processing are defined and
   interpreted the same as commands for use with individual files (see
   14.2.3), except a command which is to be used by the [Shift+^F9] processing
   must be preceded by the caret character ("^").  This identifies it as a
   command for repetitive, multi-file processing, rather than for use only on
   the current file.  Commands starting with "^" are ignored when EDDY
   processes the [Shift+F9] keypress; commands without the initial "^" are
   ignored during [Shift+^F9] processing.

   This allows you to specify different processing for the same files, depen-
   ding on whether they are processed singly or as a group.

   For example, suppose you want to use your editor on a single program source
   file, but compile or assemble to get listings of source files you have
   modified and tested satisfactorily.  This is the way the two commands below
   could be used if they were contained in EDDY.USE.

                        *.ASM C:\PE\PE2 /PC:\PE\ASM.PRO %1

                       ^ *.ASM C:\MASM\MASM %1,NUL,C:\LIST;

   You would simply display the appropriate directory, "(Ignore)" any .ASM
   files you don't wish to assemble, and then press [Shift+^F9].

   If the file doesn't match any definition in EDDY.USE, you may use EDDY's
   default point-and-shoot command.

   After executing the command, EDDY normally returns immediately to the EDIT
   directory display.  If you want to pause after each file is processed, use
   a "|" (the DOS piping symbol) in the command, right after the "^".
   Continuing with the previous example, the command in EDDY.USE would be:

                         ^| *.ASM C:\MASM %1,NUL,C:\LIST;

   EDDY v.7c User's Manual   Copyright (C) 1987-93 by John Scofield  page  58



   15.  QUIT Command - [F10], [Esc]

   When you are through with EDDY, press [F10].  [F10] will restore your
   default drive and directory to the settings they had when you executed EDDY
   (or to your "recall" directory, if you have selected one as described
   below). EDDY will terminate immediately and return to DOS.

   If you have changes pending which have not yet been processed by UPDATE,
   EDDY will remind you that there are such changes, and ask you to confirm
   that you want to QUIT anyway.

   One exception to this may occur when option /K is used.  Pressing [F10]
   when a message is displayed and waiting for a key press will only erase the
   message (like any other key).  You must press [F10] again to terminate.

   Some users prefer to use [Esc] as a way to QUIT from EDIT.  If you want to
   QUIT by using [Esc], just press it and hold it down.


   15.1 Directory Recall - [Shift+F10], [Shift+^F10]

   [Shift+F10] selects the current working directory as the "recall"
   directory.  Directory recall is a "place-holding" mechanism, used in two
   ways:  1) When you exit from EDDY, this directory will be set as the DOS
   default, and 2) If you press [Shift+^F10], the directory will be "recalled"
   as the new working directory.  If no recall directory is selected, the DOS
   default directory, as it was before you executed EDDY, will be used.

   15.2 Exit to Directory - [Alt+F10]

   [Alt+F10] exits from EDDY -- just like [F10] -- but leaves the current
   working directory as the DOS default.

   [Alt+F10] may also be used from the directory tree diagram display (see
   Section 5.3.2).  If you press [Alt+F10] in that case, EDDY will exit to the
   directory that is currently highlighted in the display.


   15.3 EGA and VGA Display Control - [^F10]

   If you have an EGA or VGA monitor, EDDY normally resets the display to the
   same number of lines that were in use when EDDY was executed.  However, if
   you use [^F10] to quit, the result is the same as [F10], except the display
   will be left with the number of lines per screen you have set (by using
   option /E) while in EDDY.

   16.  FIND and/or REPLACE String in File, Disk or RAM

   To find a string, press [Alt+f] when the EDIT mode cursor is on that
   display entry, or when in LOOK mode.  (In LOOK mode, [/] or [\] have the
   same effect as [Alt+f].) If you want to search through all files in the
   working directory, press [^f] -- see Section 16.5.

   As an example, suppose you were using EDDY to LOOK at this file
   ("EDDY.DOC") and were positioned to the "Technical Support" section.  If
   you pressed [Alt+f], the display would be similar to Figure 16-1.

   The second line in the window shows a series of "5F"s and underlines.  The
   underlines have no special significance.  They only mark the place where
   you may enter the string you want EDDY to find.

   When you have entered the string EDDY is to search for, press [Enter] for a
   "close" match search or [^Enter] for an exact match.

bug, surely!), if you take the trouble to report it, I'll try to solve it.
And I'll get back to you with a fix, if possible.

EDDY's PATCH command, using an area within EDDY reserved for this purpose,

   A "close" match will ignore upper and lower case differences.  One or more
   blanks in the string will match any number of consecutive blanks, carriage
   returns, line feeds or TABs (or any combination).  An exact match requires
   that every character match completely, including case and blanks.

   A close match will also find words that have been hyphenated and broken
   across two lines.  If you enter the string "bicycle" and then ask EDDY for
   a "close" match, it will find any occurrence of "bicycle" or even of "bicy-
   cle" (i.e., broken at the end of the line).

   Once you have entered a string, that string becomes the default for any
   later FINDs, on the same or other file.

   Exact match FINDs are much faster than "close" matches.

   In LOOK mode, you may press [f] to repeat the previous FIND, using the same
   string and the same type of match (close or exact).

   When EDDY finds the string, it goes to LOOK mode with the line containing
   the string at the top.  The first byte of the string is highlighted, and it
   blinks.  If there are long lines, and the string is off-screen, EDDY will
   move the display window to show the string.

   If the string begins with a carriage return or line feed, the display will
   be in hex format, even if it was in ASCII when the search began.  This is
   because these characters are used as line break controls, and do not appear
   in an ASCII display itself; therefore, hex format is used.

   If the string was not found, EDDY will "beep", the message "Not found" will
   be displayed, and the last page of the file will be shown.

   You may interrupt EDDY's search by pressing any key.


   16.1 Entering New FIND Strings

   The dialog box for FIND (and FIND & REPLACE -- see Section 16.6) is
   different from other dialog boxes.  This is because of the requirement to
   enter two incompatible data formats (hex and ASCII) on the same line.

   You may notice that the line where you enter strings looks a lot like
   EDDY's PATCH mode display.  In fact, the same data entry routines are used,
   and you enter your string just as though you were patching this line.

   Values 00 - 7Eh may be entered in ASCII format.  00h - 19h may be entered
   by using the [Ctrl]-shifted keys:  [^@], [^a], etc.  In hex, all values may
   be entered.  [Tab] toggles between hex and ASCII; if you don't like [Tab]
   for this purpose, see Section 8.2.1.  If [Tab] is not the toggle key, it
   can be used to enter TAB (09h) bytes in ASCII format.

   If any part of the string is entered in hex, or if the string has a hyphen
   in it, matches to words broken over two lines will not be found.

   EDDY v.7c User's Manual   Copyright (C) 1987-93 by John Scofield  page  61



   Under the data entry line, marking the end of the string, is an up arrow
   (shown in Figure 16-1 as "^").  This arrow normally points to the last
   character entered, although you may move back to change a character if you
   make a mistake, and the arrow won't move.  To mark the end of the string at
   another place, move the cursor to that place and press [Up].

   If you begin entering characters in the first (leftmost) position of the
   string, EDDY erases whatever previous string was there and accepts your
   input as a completely new string.  However, if you move the cursor to some
   position further to the right, and enter your first character there, you
   can make changes to the previous string (including the first position).

   You may also use [Ins] and [Del] to edit FIND strings.

   Two other features provide a lot of flexibility for FINDing data:  the
   "global match" character and the "don't match" attribute.


   16.2 Global Match Character - [Alt+g]

   The global match character works like the "?" wild card in DOS.  If a FIND
   string has the global match character, that position in the string will
   match any byte.  For example, the FIND string "str?ng" will match "strxng",
   "str@ng", "str ng", etc.  The default global match character is "?".

   If you want to search for a string which includes the character currently
   used for global matching, you can specify any other character by pressing
   [Alt+g] and then typing the new global match character.  You may use any
   character except space for global matching.  The new global match character
   remains in effect until changed by another [Alt+g].


   16.3 "Don't Match" Attribute - [Alt+k]

   You may also give any character in the FIND string the "don't match" (or
   "match anything BUT this") attribute.  This means that the character in
   that position in the string will match any character in the file EXCEPT the
   actual character in the string.  To give this attribute to a character,
   press [Alt+k] and then type the character.  The character will be high-
   lighted on the screen to remind you it has the "don't match" attribute.

   For example, if the second character in the string "xyz" were designated as
   "don't match", the string would be a successful match to "x0z", "x=z",
   etc., but would not match "xyz".

   EDDY v.7c User's Manual   Copyright (C) 1987-93 by John Scofield  page  62



   If your string contains a global match character, you may designate it as
   "don't match" if you wish.  In this case, that character (in that string
   position only) is no longer treated as a global match.  For example,
   suppose the global match character is "?", and you use the string "abc?"
   with the last character as "don't match".  Then EDDY would not find "abc?"
   if it occurred in the file, but it would find "abc-" or "abcd", etc.

   Similarly, if you designate a blank as "don't match", it will no longer
   match multiple blanks, carriage returns, line feeds or TABs.  Instead, it
   will simply be treated as a match to any single character except blank.

   Typing any character in a string position previously designated "don't
   match" removes the "don't match" attribute.


   16.4 FIND "Any Text"

   Sometimes you may want to search a .COM or .EXE file to see what messages
   might be lurking in it (such as "gotcha!" or "virus", for example).  Or you
   might want to see how many words in a document have more than "n" letters.

   You can do things like this by entering a FIND string that has only "?"s
   (or whatever global match character you are using).  If your string has
   only "?"s, it will FIND any string of upper- or lowercase LETTERS that is
   at least as long as your string.  It will also match strings containing
   spaces, as long as there are not two or more in a row.

   Thus, the FIND string "?????" would match:
                           "abcde", "AbcDE", or "a c e"
   but would not match:
                           "ab&de", "Ab-DE", or "a  de".

   You can also use the "don't match" attribute ([Alt+k]) with strings of
   "?"s.  Don't match in this case means match only if the character is NOT a
   letter ("space" is not a letter).

   For example, if the middle "?" in the above FIND string were given the
   "don't match" attribute, the string would match:
                           "ab&de", "Ab-DE", or "a  de"
   but would not match:
                           "abcde", "AbcDE", or "a c e".

   EDDY v.7c User's Manual   Copyright (C) 1987-93 by John Scofield  page  63



   16.5 Search for FIND String in All Files - [^f]

   To search through all files for the given string, press [^f].  The first
   file from your current display will be displayed in LOOK mode, and the FIND
   window will be ready for you to enter the FIND string.

   If a match is found, the first character is highlighted in a LOOK mode
   display, as for [Alt+f] or [f].  If there is no match in that file, the
   search will proceed to the next file, continuing until there is a match or
   there are no more files.

   After a match, you have 4 choices:

   1.  Pressing [f] searches the file for any more matches, and proceeds to
   the next file if no match is found.

   2.  You can press [Alt+f] to change the FIND string, and the new string
   will used for matching from that point on.

   3.  [Esc] exits from the current file without searching further, and moves
   on to the next file.

   4.  To stop the search and return to EDIT mode, press [^c] or [BackSpace].


   16.6 FIND and REPLACE - [Alt+r]

   To replace occurrences of the FIND string with a new string (the "REPLACE
   string"), press [Alt+r].  The FIND window will be expanded to allow entry
   of a REPLACE string in the lower portion of the window.  REPLACE strings
   are entered exactly the same as FIND strings, and may be ASCII and/or hex.

   Switching between the two parts of the window is done with the cursor keys:
   [Up] moves from the REPLACE part to the FIND part, and [Down] moves from
   FIND to REPLACE.

   To shrink the window back to normal FIND-only size, press [Alt+r] again.

   If you begin the search with the expanded window on the screen, then the
   REPLACE string will be used whenever a match is found for the FIND string.
   When you begin the search, you will be asked whether you want EDDY to pause
   for you to confirm before replacing, or just to go ahead and make the
   replacement automatically.

   If the REPLACE string is shorter than the FIND string (e.g., with a "close"
   match that includes white space), the REPLACE string will be padded with
   trailing blanks as required to make the two strings the same length.  A
   REPLACE string may not be longer than its corresponding FIND string.

   EDDY v.7c User's Manual   Copyright (C) 1987-93 by John Scofield  page  64


   17.  File Selection by Filtering

   You may use EDDY's "filter" feature to display only files which have
   certain attributes (e.g., read only) and/or particular timestamps (e.g.,
   files with timestamps later than 9 A.M.  today).  Filter values may be
   entered from the command line or while executing EDDY.  When filters are in
   use, they are shown in the top line of the display.

   If the working directory has files that are not displayed because a filter
   is being used, an asterisk will appear just to the right of the file count
   field in the display heading (e.g., "53*files" instead of "53 files").

   Filters normally have no effect on subdirectory entries in the display.
   All subdirectories are displayed, regardless of attribute settings or
   timestamp, with two exceptions:  if the directory attribute is selected as
   part of an attribute filter or if the display sequence is "unsorted", then
   subdirectory entries are filtered in the same manner as other file entries.

   When you set or change a filter and there are other changes pending, such
   as renaming, copying, etc., EDDY checks to be sure that all files with
   changes will still be included in the display after the new filter takes
   effect.  If not, you will be warned that some changes will be lost, and
   given a chance to decide whether to proceed or not.


   17.1 Filtering by Attribute

   You may filter the directory display so that it contains only files with
   attributes you specify, by using an attribute selection parameter.


   17.1.1 Attribute Selection from the Command Line

   A command line attribute selection parameter begins with a plus sign ("+")
   to distinguish it from a path specification.  The "+" is followed by one or
   more letters for the file attributes you choose.  The letters to use are
   the same as the letters in EDDY's display heading:  R, H, S, D, A or N.

   To select files which have the attribute ON, enter the letter in upper
   case; for files with the attribute OFF, lower case.  Thus, to select only
   files which are "hidden", enter "+H"; for files which are read-only and not
   modified since last backup (i.e., "archive" attribute off), enter "+Ra" or
   "+aR" (the order makes no difference).  If more than one attribute is
   selected, all must match in order for a file to be selected.

   If you specify an incorrect letter, or use the same letter in both upper
   and lower case, EDDY will terminate with an "Invalid format" error message.

   Attribute selections are shown in the display heading.  The letters for the
   selected attributes will blink, showing they're used for file selection,
   and they will be the same case -- upper or lower -- as you specified.

   17.1.2 Attribute Selection in EDDY - [Alt+a]

   Press [Alt+a] for attribute selection while executing EDDY.  You may then
   enter the attributes to be used for filtering.  [Esc] restores the
   attribute filter previously in effect, if any.

   To select an attribute, press the key for the corresponding letter -- [R],
   [H], [S], [D], [A] or [N].  Pressing a key once selects "attribute ON",
   twice selects "attribute OFF", and a third time deselects the attribute.
   When you are satisfied with the selection, press [Enter].

   You may also select attributes by moving the cursor to an attribute and
   clicking the mouse or pressing [Tab].


   17.2 Filtering by Timestamp

   You may filter the directory display so that it contains only files with
   timestamps in a range you specify, by using timestamp selection.


   17.2.1 Timestamp Selection from the Command Line

   A command line timestamp selection parameter is enclosed in double quote
   marks Immediately following the first quote must be one of the following:
   "]", "<" or "=".  These mean that the files to be selected for display must
   have timestamps greater than, less than, or equal to the timestamp you use.

   Next, you must provide the timestamp value.  This may be a date, a time, or
   both.  Following the timestamp value is the closing quote mark.

   Leading zeros must be used when entering dates if needed to make up a two-
   digit value -- e.g., "5/31/88" would be rejected; "05/31/88" would be O.K.

   Times are based on a 12-hour clock, and must be in the form "hh:mma" for
   A.M. times, or "hh:mmp" for P.M.  Again, leading zeros are required.

   If you wish to specify both date and time, the date and time must be
   separated by one space.

   Some examples of valid timestamp values are:

    ">05/31/88 09:00p" - select files with timestamps later than this

    "=07/23/86" - select files created at any time on this date only

    "<10:30p" - select files created before this time, on any date

   EDDY v.7c User's Manual   Copyright (C) 1987-93 by John Scofield  page  66



   Normally, EDDY will re-sort the display when you use timestamp filtering.
   When the filter includes a date, the display will be sorted by date.  If
   the filter has only a time, it will be sorted by time.

   However, if you have explicitly changed the display sequence (by using
   option /1 or one of the sort commands), then filtering by timestamp will
   not cause a re-sort.

   If you make a mistake with the timestamp, EDDY will usually terminate with
   an "Invalid format" error.  However, if you leave off one or the other of
   the quotes, and your filter value includes a "<" or a ">", DOS will use
   these as redirection symbols, rather than as part of the command line.

   With "<", you will probably get a "File not found" message, while with ">"
   the "Invalid format" and logo display output from EDDY will be put in a
   (hopefully new!) file in your default directory.

   If these possibilities worry you, you may use "+" and "-" instead of ">"
   and "<", when entering a timestamp filter value from the command line.

   17.2.2 Timestamp Selection in EDDY - [Alt+q]

   Press [Alt+q] for timestamp selection.  Any timestamp filter in effect at
   that time will be cancelled, the null timestamp "=00-00-00 00:00p" will
   appear in the top line, and the cursor will move to the "=" sign.  If you
   don't want to enter a new timestamp value, press [Enter] while the null
   timestamp is displayed, and no timestamp filter will be used.

   Otherwise, the null timestamp may be edited just as though it was a normal
   file timestamp in the body of the display.  When you are happy with the
   filter value, press [Enter].  If you enter an invalid timestamp, EDDY will
   "beep" at you and move the cursor to the field in error.

   18.  Playing With RAM

   You may access your PC's main memory from EDDY, in much the same way as for
   files.  If option /R is turned ON, the display will include an entry with
   the name " memory", showing the no. of bytes of RAM in your system (as
   indicated by your system's BIOS), and the current DOS date and time.

   This entry will appear at the end of the list of files in most displays,
   with two exceptions:  if the sort sequence is inverted, the " memory" entry
   will be at the top; and if there are more files in the directory than EDDY
   can display at once, the " memory" entry will not appear at all.

   " memory" is not included in the display of number of files and bytes used.

   You may LOOK at, FIND strings in, PATCH or COPY the " memory" entry.  For
   more information on these, see the respective sections of this document.

   19.  Volume Identifiers

   DOS offers two methods of identifying disks:  volume labels and volume
   serial numbers.  EDDY provides services for both.

   19.1 Volume Labels - [Alt+v]

   To create or change a volume label on a disk, press [Alt+v].  Then type the
   new label in the dialog box on the screen, and [Enter].

   EDDY can't create labels with lower case characters, nor make a file into a
   label by changing its attributes.  EDDY does not delete labels.

   When creating a new label for an unlabelled disk, you'll get an error if
   the disk's root directory already has the maximum number of entries (112
   for a DSDD floppy) allowed by DOS, or if the label you enter is the same as
   the name of a file or subdirectory in the root.  Also, a label can't have
   leading blanks.


   19.2 Volume Serial Numbers - [^v]

   To create or change a volume serial number on a disk, press [^v].  Then
   type the new label in the dialog box on the screen, and [Enter].

   The serial number consists of 8 hexadecimal digits ("0" - "9", "A" - "F").
   There is also a hyphen displayed, but this is only for readability.  The
   hyphen is not part of the serial number.

   20.  Batch Operations

   20.1 Numeric Options

   In batch mode, you may COPY, MOVE, DELETE or DESTROY files.  The desired
   command is specified on the command line, as a "numeric" option.  The
   numbers used correspond to function keys used interactively...

             /5 - COPY files ([^F5])      /6 - MOVE files ([^F6])
             /7 - DELETE files ([^F7])    /8 - DESTROY files ([Shift+^F7])

   Other numeric options useful in batch mode are:

   /1x - "x" defines the sequence (E = extension, D = date/time, N = name,
   etc.) in which files will be processed.  Lowercase means inverted order.

   /2xxxxxx - "x"s define COPY/MOVE/DELETE Control settings (see Section 10).
   If the default settings are correct, /2 is not required.  Normal defaults
   are Y,Y,C,C,N,N.  (In batch mode, "C" is treated as "N" -- i.e., there is
   no "confirmation" step.)

   Thus, to COPY files newer than corresponding files in the target, enter a
   command like...
                               "EDDY/5  C:\WORK A:"

   To DELETE files that are duplicates of those in the target, enter...
                           "EDDY/7/2NNNNYY C:\WORK A:"

   Attribute and timestamp filters may be used to select files in batch mode.
   Files with read-only, hidden or system attributes will not be processed in
   batch mode unless they are explicitly selected by an attribute filter.

   If a file to be copied or moved is "read-only" in the target, the command
   will proceed only if the file is also read-only in the working directory.


   20.2 ERRORLEVEL

   Non-batch mode executions always leave ERRORLEVEL set to zero.

   When a batch mode execution finishes, "ERRORLEVEL" will be set according to
   the results, as follows:

   If all updates were done successfully, ERRORLEVEL will be set to zero.  If
   updates were not done because no files qualified according to the criteria
   given by the COPY/MOVE/DELETE Controls, ERRORLEVEL will be set to 255.

   Any error encountered will terminate EDDY, and ERRORLEVEL will be set to
   the standard DOS error number as applicable (e.g., ERRORLEVEL = 2 for "File
   not found", 3 for "Path not found, etc.").

   21. Disk Jockey's Delight  (format-level disk functions)

   These functions are not available when looking at remote (network) drives.

   21.1 LOOK at Entire Disk - [F3]

   If you press [F3] on the third line of the display ("Drive X:  is..."), you
   will enter LOOK mode for the entire disk, without regard to any file or
   directory structure.  In effect, the whole disk is treated as a single
   file.  The display will begin with the sector on the disk where the current
   working directory is located.

   When LOOKing at the disk, the display is always in hex.  However the
   meaning of "Offset" is different; "Offset" specifies physical disk sectors
   (normally 512 bytes each).  Here's an example of this type of display:

================================================================================

                                   Figure 21-1

   The first line of each sector's display has the logical sector number in
   the "Offset" field (0000193F in the example).  The other lines for the
   indicate the offset of the bytes from the beginning of the sector.

   EDDY v.7c User's Manual   Copyright (C) 1987-93 by John Scofield  page  70



   If the sector is the first sector of a cluster, the second line also shows
   the cluster number (0633 in the example).  Numbering starts with cluster 2,
   which begins with the first sector in the disk's data area.  Sectors in the
   DOS disk control area, which include the boot sector(s), File Allocation
   Table(s), root directory, etc., do not have cluster numbers.

   However, the starting sectors of the root directory and File Allocation
   Table(s) have "ROOT" and "FAT" respectively, under the sector number.

   You may notice the "???" strings in the first few lines of Figure 21-1;
   this is the way EDDY indicates sectors on which DOS has reported that an
   error has occurred while reading the data.  The data may not be accurate.


   21.1.1 Jumping Around

   Several "shortcut" methods are available to move the display quickly to
   various parts of the disk:

   a. Jump to Sector - [j]

   To move to a particular sector, press [j].  EDDY will ask you to enter the
   sector number, in hex.  When you have done so, the display will move
   accordingly.  If the number entered is larger than the last sector number
   on the disk, the last sector will be displayed.

   b. Jump to Cluster - [Alt+j]

   To move to a particular cluster, press [Alt+j].  EDDY will ask you to enter
   the cluster number, in hex.  When you have done so, the display will move
   accordingly.  If the number entered is larger than the last cluster number
   on the disk, the last cluster will be displayed.

   c. Jump to Working Directory - [Alt+w]

   Pressing [Alt+w] moves you to the first cluster of the working directory.
   (This is automatic when you LOOK at disk, but can also be used any time.)

   d. Jump to Target Directory - [Alt+t]

   If there is a target directory, and it is on the same disk as the working
   directory, it will be displayed if you press [Alt+t].

   e. Jump to Starting Cluster - [Alt+s]

   A directory entry contains a pointer (cluster number) to the first disk
   area allocated to that file or directory.  This pointer remains in the
   entry even after the file has been deleted, until that entry is used again.

   To look at the data on the disk at the logical start of the area allocated
   to a file or directory (the cluster), position the directory entry on the
   first line of the screen and press [Alt+s].

   EDDY v.7c User's Manual   Copyright (C) 1987-93 by John Scofield  page  71



   f. Jump to Next Cluster - [Alt+n]

   Space on the disk is allocated in clusters, and the record of space alloca-
   ted is maintained in "chains" of cluster numbers, in the FAT.  To view the
   data in the next cluster in the chain for a file, press [Alt+n].

   g. Jump to Unallocated Cluster - [Alt+u]

   When [Alt+u] is pressed after entry to LOOK, the first cluster that has not
   been allocated is displayed.  After that, [Alt+u] displays the next
   sequential unallocated cluster.  When all unallocated clusters have been
   displayed, the display returns to the first one.

   EDDY v.7c User's Manual   Copyright (C) 1987-93 by John Scofield  page  72



   21.1.2 Displaying Directory Entries - [Alt+d]

   If you have a directory entry displayed at the top of the screen, such as
   would be the case after an [Alt+w] or [Alt+t] command, described above, you
   can use [Alt+d].  The result will be a display (nearly) like EDDY's EDIT
   mode format for that entry.  An example is given in Figure 21-2.

   The attributes are shown by the letters "RHYDASV".  These are the same as
   in the EDIT mode heading line (except "V", which indicates the volume label
   attribute).  In this display, they show the attribute settings directly;
   upper case means attribute ON, lower case means OFF.

   The "cluster" number is the starting cluster which is (or was, if the entry
   has been deleted) allocated to the file or subdirectory.

   After displaying a directory entry, any keypress will clear it.  If the key
   used is also a valid command, it will be executed.

   21.2 PATCH Anything on a Disk - [F4]

   You can patch disks without regard to logical or physical file structure.
   This capability should be used with caution, as it is quite possible to
   make a disk unusable by patching the wrong byte(s).  The first part of the
   disk (before cluster 0002) contains formatting and space allocation
   information, and is the most sensitive area.  Therefore, EDDY will warn you
   and ask for confirmation before patching there.

   If this capability worries you, see the next section.

   WARNING!  DO NOT USE SECTOR PATCHING ON "COMPRESSED" OR "EXTENDED" DRIVES
   -- I.E., DEVICES CREATED AND MANAGED BY STACKER, DOUBLEDISK, SUPERSTOR, AND
   SIMILAR PRODUCTS.  PATCHING FILES STORED ON THOSE DISKS IS PERFECTLY SAFE,
   HOWEVER.  SEE SECTION 21.6 FOR MORE INFORMATION.


   21.3 That's Too Dangerous!

   These very powerful features can be extremely dangerous in the hands of an
   inexperienced user, or worse, someone who is intent on doing damage.  For
   this reason, some users prefer not to have all the capabilities readily
   available, especially on machines that may be used by more than one person.

   By creating a customized version of EDDY, you can PERMANENTLY disable the
   absolute sector patching feature.  Just answer "n" when the question:
               "Allow disk PATCHing by sector in new EDDY (y/n)?"
   is asked, and the customized version will have this feature disabled.  If
   you answer "y", you can change ANYTHING on a disk, including format data.

   Even if you customize again, using the disabled EDDY.COM as the master
   copy, sector patching cannot be re-enabled.  Your original copy of EDDY.COM
   (or EDDY.OLD, after customizing), will still do sector patching, however,
   so it should be kept safely tucked away where only you can get to it.


   21.4 FIND Strings Anywhere on a Disk - [Alt+f]

   The FIND command works the same as with a file.  Refer to Section 16.


   21.5 COPY Disk (or parts of it)

   To copy by physical disk area, first select the portion to be copied, and
   then tell EDDY to copy it.  The commands used in connection with these
   steps are described below.

   EDDY v.7c User's Manual   Copyright (C) 1987-93 by John Scofield  page  74



   21.5.1 Select Disk Area

   a. Mark/Unmark Cluster(s) - [m]/[F2]

   Clusters to be copied are defined by "marking" them.  This is done by
   moving the LOOK display to the cluster desired, and pressing [m].  If no
   clusters are currently marked, the single displayed cluster will be marked.
   If one or more clusters are already marked, the displayed cluster, plus all
   the clusters between it and the currently-marked clusters will be marked.
   Thus, the marked area is always a contiguous set of clusters.

   Only areas of the disk which are formatted for file storage i.e., cluster 2
   and beyond, can be marked in this way.  Lower-numbered sectors (boot
   sector, FAT, root directory, etc.) can only be copied as part of the entire
   disk image (See Section 21.5.3).

   Pressing [F2] (the "Undo" key) unmarks any clusters previously marked.

   b. Jump to Marked Cluster - [Alt+m]

   If you press [Alt+m], the display will move to the first marked cluster, if
   any, unless it is already displayed.  In the latter case, if there are more
   marked clusters, the display will move to the last one.  [Alt+m] has no
   effect if there are no marked clusters, or if the entire disk is marked.

   21.5.2 COPY Marked Area - [Enter]

   When you have defined the portion of the disk you want to copy, by marking
   it, press [Enter].  After you confirm -- as with other update-type
   operations -- by pressing [Enter] again, the area you have selected will be
   copied to the target directory.

   Copying will always be to a file called "DRIVE.x", where "x" is the letter
   of your working directory's drive.  If a file with this name already exists
   in the target directory, you'll get a warning message and EDDY will let you
   decide whether to proceed or not.

   After copying is complete, EDDY unmarks all marked areas and remains in
   LOOK mode.  You may mark additional areas as desired, and copy those areas
   as well.  This may be repeated as often as you like (as long as there is
   enough space in the target).

   As long as you do not return to EDIT, all data copied will be added to the
   end of the data in the "DRIVE.x" file.  This allows you to build that file
   without respect to the order of clusters on the disk.

   EDDY v.7c User's Manual   Copyright (C) 1987-93 by John Scofield  page  75



   21.5.3 Disk-Image Copying - [Shift+F5]

   To copy the entire disk to a file, move the cursor to the "Drive" line
   of the display and press [Shift+F5].  The target directory must be on a
   separate disk, which must be larger than the disk being copied.

   This file will be 4 bytes longer than the disk being copied (6 bytes if
   it's a hard disk).  EDDY writes the sector size and no. of sectors of the
   source disk at the beginning of the file, for checking compatibility if
   EDDY is used to restore the file to a disk (see next section).  If you need
   a file that is an exact image of your disk (i.e., doesn't have these extra
   bytes), use EDDY's PATCH command to delete the first 4 (or 6) bytes.

   This feature will not work with copy-protection schemes that use non-DOS
   formats for some or all parts of the disk.  Hidden files, non-standard
   directory structures, and unique boot programs are no problem, however.

   "That's interesting", you say, "but why would I want to do that?"

   There are several possible uses for this feature:

   a.  Upload/Download Entire Disks

   Sending entire disks electronically is difficult without EDDY.  If you have
   a disk you'd like to transmit via modem, use disk-image copying.

   Then you can compress the resulting "DRIVE.x" file, and transmit.  (For
   maximum compression, use a newly-formatted disk to create your original.)
   Make sure the receiver has a copy of EDDY, so that he can rebuild the disk
   as described in Section 21.5.4.

   b.  Make Multiple Disk Copies Quickly

   Another use for this feature is in making multiple copies of a single disk.
   Using EDDY to do a disk-image copy and then doing repeated disk-image
   restores, as described in 21.5.4 below, is a lot faster than repeating
   DOS's "diskcopy" several times.  It's particularly effective if you copy
   the disk image to a RAM disk.

   c.  Reduce Disks Needed for Backup

   A lot of software packages have a LOT of disks (Borland C++ comes to mind).
   Common sense tells us we should make backup copies of these disks, in case
   the originals go bad someday (There's ANOTHER 11 disks to store!).

   With EDDY, you can copy the original disks to image files, compress them,
   and copy two (sometimes 3) of those compressed files to one high-density
   disk.  You've just cut your backup disk count at least in half.

   If you ever need the backup, just uncompress the file for the disk you
   need, then use EDDY's disk-image restore, and you're ready to go.

   EDDY v.7c User's Manual   Copyright (C) 1987-93 by John Scofield  page  76


   d.  No-Hassle Hard Disk Backup

   If you have two hard disks, you can use disk-image copying to backup the
   smaller on the larger -- and it's MUCH faster than other methods.  I
   routinely backup my laptop's disk to an external hard disk.  It takes about
   6 minutes, with NO disk swapping or other manual intervention,for a 20 MB
   hard disk.  And there are NO floppies to store and keep track of.


   21.5.4 Disk-Image Restore - [Shift+F5]

   This is the command that makes disk-image copying, described above, so
   useful.  This is how you rebuild identical-to-the-original, fully
   functional disks from the disk-image files.

   Unlike the other commands described in Section 21, [Shift+F5] is used in
   EDIT mode.  It writes a file previously created with EDDY's disk-image copy
   capability to an entire physical disk, overwriting everything, including
   format, boot and file allocation information on the target disk.  The
   result is an exact copy of the disk originally used to create the file.

   When this command is used, the display will show "Copy image" next to the
   file involved.  The actual copying will be done only when you enter UPDATE,
   by pressing [Enter] as normal from EDIT.  Since the entire target disk will
   be overwritten by this operation, [Shift+F5] cannot be used if any other
   COPY or MOVE operations are pending.

   EDDY checks the disk format of the target disk against the information
   saved from the original disk.  If there is any difference, or if the file
   size has been changed since it was created, the restore will not proceed.


   21.6  "Compressed" or "Extended" Disks (Stacker, etc.)

   Some of the things EDDY can do to your disks are things you shouldn't do
   if using disk capacity expansion utilities such as Stacker, DoubleDisk,
   SuperStor, or similar products.  Specifically, patching disk sectors (files
   are OK) and moving or rewriting directories are features likely to cause
   problems (i.e., your data may disappear!) if used with these "drives".

   Therefore, EDDY tries to identify such drives before proceeding with any of
   these functions.  If a drive is identified as being one of these, you will
   see the message... Not supported for this disk ...and EDDY won't proceed.

   The first time one of these functions is requested on a drive, if EDDY
   can't decide automatically whether it's a real drive (some vendors provide
   information on how to detect their products, and some don't) you will be
   asked... Is <x:> a "compressed drive" - Stacker, DoubleDisk, etc (y/n)?
   ...and EDDY will react according to your answer for the rest of that
   session.  If you customize, this information will be recorded permanently,
   so you won't be pestered by the question any more.

   22. Directory Optimization

   There are three main reasons for changing the order of directory entries on
   disk:  to improve access speed, to free wasted disk space, and/or to allow
   directory information to be presented in some non-standard sequence that's
   unique to a particular application or user's preference.

        Access Speed
        ------------
        When DOS needs to access a particular file or subdirectory, it
        does a sequential search from the top of the directory, until it
        either finds the entry it's looking for, a never-used directory
        slot, or the end of the directory.  Clearly, if the entry wanted
        is near the beginning, and there are no directory slots present
        that are marked as "deleted", it'll be found quicker.

        Disk Space
        ----------
        Directories may grow as large as necessary to hold as many files
        as are placed in them, up to the limit of available disk space --
        except for the root directory, which has a size fixed at format-
        ting time.  Once they have grown, they NEVER shrink, even if you
        delete all the files in them.  The only way they get smaller is
        when the entire directory is deleted -- OR use EDDY to erase
        deleted entries and free the associated space (directory packing).

        Non-standard Sequences
        ----------------------
        Many utilities offer a variety of sequences for sorting directo-
        ries:  typically filename, extension, size or timestamp.  However,
        sometimes there's a need to put directories in an arbitrary
        sequence, which can't be handled by the usual sorting utilities.
        This might be to get the directories in the desired order for a
        disk optimizer, or just because you prefer to see them listed
        that way.  EDDY lets you put things in any order you please, by
        using the "Shuffle" command (See Section 22.2).

   WARNING!  DO NOT USE DIRECTORY OPTIMIZATION ON "COMPRESSED" OR "EXTENDED"
   DRIVES -- I.E., THOSE DEVICES CREATED AND MANAGED BY STACKER, DOUBLEDISK,
   SUPERSTOR, AND SIMILAR PRODUCTS.  SEE SECTION 21.6 FOR MORE INFORMATION.

   EDDY v.7c User's Manual   Copyright (C) 1987-93 by John Scofield  page  78



   22.1 Sorting a Directory

   Directories are normally sorted for display purposes only (as described in
   Section 1.4.2) to group files in ways -- by name, date, etc.  -- that make
   it easier to work with them.  Usually, displaying this way is enough, and
   there's no need to keep the sequence permanently on disk.

   When you do want to make the sequence permanent, however, just press
   [Shift] at the same time as you press the regular sorting commands; e.g.,
   press [Alt+Shift+n] for sorting by name, [Alt+Shift+d] for sorting by date,
   etc.  -- except [Alt+Shift+u] has no effect.  When the directory has been
   sorted by using the shifted commands, the letter for the sequence code at
   the bottom of the screen will blink.

   The blinking sequence code indicates that when you UPDATE, the directory
   can be rewritten to disk in that sequence.  After all file-related UPDATE
   actions -- copy, move, delete, rename, etc.  -- have been done, the
   message...
                      Write sorted directory to disk (y/n)?
   ...will appear, and EDDY will wait for your reply.  If you answer "y", the
   rewrite process will begin.

   If the current directory display includes only some of the files in the
   directory, due to a file specification used (e.g., "*.DOC"), or attribute
   or timestamp filtering, then the entries for those files will be rewritten
   first, before the remaining entries in the directory.  The result will be a
   directory display with two, separately sorted parts

   Any entries marked as "erased" by DOS will be moved to the end of the
   directory, to minimize time wasted by DOS in searching through them when
   using the directory later.

   For a way to eliminate this wasted time altogether, refer to Section 22.3.

   Before starting the rewrite, a check is made to be sure no files are
   currently open in the directory.  Rewriting with open files is likely to
   cause directory corruption, as DOS maintains pointers to absolute disk
   locations for data about files that are open, and rewriting will probably
   move that data during the process.

   EDDY uses some undocumented data structures within DOS to check for open
   files.  If EDDY finds data there that doesn't look valid, and therefore is
   unable to check for open files, this message...
             Unsure if files open in this directory. Continue (y/n)?
   ...will be displayed.  If there are no files open, answer "y"; if there
   are, answer "n".

   EDDY v.7c User's Manual   Copyright (C) 1987-93 by John Scofield  page  79



   22.2 Shuffling a Directory - [Alt+F6]

   EDDY lets you arrange your directories in any order you wish*.  Rather than
   sorting in the standard ways  -- name, size, etc. -- you may move the
   directory entries around to suit your own preferences, and then write them
   permanently in that sequence.

   This is useful to improve access speed to frequently-used directories and
   files, by placing them at the beginning of their respective directories.

   Shuffling is accomplished as follows:

   1.  Move the cursor to the directory or file you wish to move, and press
       [Alt+F6].  The action tag "Shuffle" will appear next to that entry.

   2.  Move the cursor to the entry located where you want the tagged entry to
       be placed, and press [Alt+F6] again.  The tagged entry will be moved to
       the position immediately after the current entry.

   When one or more entries have been shuffled, the sequence code shown at the
   bottom of the screen will change to a blinking "?".  If you UPDATE, the
   directory will be rewritten in the order it is displayed, and after the
   UPDATE the indicated sequence will be "U" (unsorted).


   22.3 Packing a Directory

   Erased directory entries are placed at the end of the directory by the
   rewrite process.  However, they still occupy space and they still waste
   search time when a file is "Not found" (this can become significant with
   long "PATH statements).  On the plus side, an erased entry MAY be used to
   recover a file deleted by mistake.

   If you are sure you won't need to recover any files deleted in a directory,
   then use EDDY to get rid of them.  Depending on how many there are, you may
   get some additional free space on your disk, as EDDY will shrink the
   directory to the minimum size needed to hold the entries remaining.  You
   will also eliminate time wasted in searching through them.

   When the directory rewrite process begins, if any directory slots are
   marked as "deleted", EDDY will ask...
                    Erase "deleted" directory entries (y/n)?
   If you answer "y", the directory will be "packed" as it is rewritten.

   ---------------------------------------------------------------------------

   * NOTE:  There are two exceptions to "any order":  the '.' and '..' entries
   at the beginning of a subdirectory can't be moved, nor can the DOS system
   files (IBMBIO.COM, IBMDOS.COM or similar name) at the beginning of a root
   directory be moved.

   22.4 Had a Problem?  Don't Panic!

   This process has been exhaustively tested by the author and many users,
   without any problems.  However, some of us are hesitant (read
   "intelligent") about using programs that mess with our disks in
   non-standard ways.  Therefore, the following information is offered.

   Sorting and rewriting directories cannot be done using the standard DOS
   application services.  EDDY handles this by writing directly to the
   directories, and using DOS services where available.  No direct
   manipulation of the File Allocation Table (FAT) is involved.

   The steps involved in sorting and rewriting a subdirectory are:

   1.  Set the "directory" attribute OFF in the subdirectory's entry in the
       working directory.  This makes DOS think the subdirectory is a file.

   2.  Read the "file", using standard DOS services.

   3.  Sort the directory entries in memory, and rewrite the "file"
       (packing it if appropriate), again using standard DOS services.

   4.  Turn the "directory" attribute back ON in the directory.

   If there is a problem with any of the above steps (e.g., a power failure
   during the update), recovery is straightforward.

   - If the subdirectory is still shown as a directory entry in its parent
   directory, there's no problem.

   - If there was a problem with step 4, the subdirectory will be shown as a
   "file" (i.e., no "directory" attribute) in the parent directory, with a
   length of zero.  Don't panic!  There's only one little bit that has to be
   changed.  To fix this problem, LOOK at the disk to display the raw
   directory data.  Move the display until the entry for the "file" is at the
   top, and PATCH offset 0Bh to "10h".  Your directory is now restored.  Exit
   from LOOK, and you'll see the result.

   23.  Data Recovery

   These functions are not available when looking at remote (network) drives.

   When you accidentally delete a file, there are many excellent products to
   help you recover your data.  With luck, your file was allocated to contig-
   uous disk clusters, its directory entry has not been re-used, and no part
   of it has been overwritten.  In this case, and even some more complicated,
   these programs can often recover your file automatically.  If this solves
   your problem, congratulations!  There's nothing easier.

   However, normally Mr. Murphy has made his contribution by the time you
   realize you have a problem.  In this situation, EDDY offers facilities to
   assist you in recovering your data as easily as possible, and SAFELY!

   The job is made a little easier by some of the commands provided by EDDY.
   It is safe because all writes are to the target disk, which normally is
   physically separate from the one containing your data (although you may
   override this if you choose).  Thus, there is no chance of making things
   worse, by erroneously patching FATs or directories, or by copying data you
   are trying to recover on top of data you will want to recover later.

   The steps for file recovery are...

        1.  Set your working directory to the directory which used to contain
        the file which had the data you want to recover.  Move to the "Drive
        X: is..." line and press [F3].  Then press [Alt+w] to move to the area
        of the disk containing the working directory.  Continue with Step 2.

        If the directory has been deleted too, start with the (former) parent
        directory as your working directory, and use Steps 2 and 3 to move to
        the disk area containing the deleted directory information.  Then
        begin with Step 2 from there.

        2.  Move the display until the line containing your deleted filename
        (or directory) is at the top of the display.  Only the first byte of
        the filename will be different:  that byte will be either "E5" or "05"
        hex; the rest of the name will be unchanged (Note that there is no "."
        between the name and extension parts).

        If you'd like a clear display of the directory entry at the top of the
        display, press [Alt+d].  This can be particularly useful if there are
        several entries that might be the one you're looking for, or if the
        name was only one byte long, because you may be able to identify the
        correct entry by the former size, date, time and/or attributes.

        If you don't find the filename in the first cluster of the directory,
        press [Alt+n] to move to the next cluster allocated to the directory,
        and continue looking for the filename.

        If you can't find the filename, go to Step 4, below.

   EDDY v.7c User's Manual   Copyright (C) 1987-93 by John Scofield  page  82



        3.  When you have the filename at the top of the screen, press
        [Alt+s], to display the starting cluster of the deleted file.  If the
        data looks like what you expected to find, proceed to Step 5.

        If the data there doesn't look like it belongs to that file, the
        cluster has probably been re-used by DOS to store another file.  In
        this case, continue with Step 4.

        4.  This step is needed when you have to do things the hard way --
        when directory entries or data file space has been re-used, and things
        are not so easy to find.

        The task is to identify the first cluster containing data belonging to
        your file.  If you know what the data looked like, you may be able to
        locate it by using the FIND command to locate some known string.

        Otherwise, you'll have to scan through the clusters until you find one
        that contains likely-looking data.  This is not QUITE so hard as it
        might be, because EDDY provides you with a way of looking only at
        clusters which are currently unallocated, which is where any data from
        deleted files will be found.  (But see note at bottom of this page.)
        Use [Alt+u] to look at the unallocated clusters, one after another.
        This is still tedious, but at least it's better than deciphering the
        FAT to locate these clusters.

        When you've found the cluster you want to start recovering, proceed to
        the next step.

        5.  Mark the selected cluster, using [m].

        6.  Look at the next cluster.  If it appears to contain the next part
        of the file, mark it, too.  Repeat this step until the data in the
        current cluster looks like it's from another file, or from this one,
        but out of sequence.

        7.  Write the marked cluster(s), by pressing [Enter].

        8.  Find the next cluster that looks like it logically follows the
        last one written, using FIND or [Alt+u], as appropriate (refer to Step
        4 for an explanation of these).

        9.  Repeat steps 5 - 8 until you feel you have all the data from your
        file (or as much of it as is left, if other files have overwritten
        some of the clusters previously used by your file).

   NOTE:  Some implementations of DOS do not de-allocate clusters when a file
   is deleted, but instead wait until the space is needed and then do a
   "garbage collection".  This can make recovery of a deleted file MUCH
   easier, as the cluster allocation chain remains intact.  Just restore the
   first byte of the filename in the directory and Voila!, there's your file.

   24.  UPDATE Mode - [Enter], [^Enter]

   When you want to apply the changes you have made in EDIT mode to disk,
   press [Enter] to go to UPDATE mode.  EDDY will display the net change in
   number of bytes used on disk which will result from your update.  A "+"
   means more bytes will be used, and a "-" means some bytes will be freed.

   Before actually writing anything to disk, EDDY will ask you to confirm that
   you want to proceed, by pressing [Enter] again.  This is to avoid writing
   to disk before you are ready because of touching a key by mistake.

   If you use [^Enter] to start the UPDATE, EDDY will ask you whether to put
   the current date/time on files copied.  UPDATE normally -- after [Enter] --
   leaves the timestamp unchanged on a file that has been copied.  If you use
   [^Enter] instead, EDDY will ask whether you want to do this or not.

   (If you have customized EDDY as described in Section 24, EDDY assumes you
   are familiar with the program; in this case, no question is asked, and the
   timestamp on copied files will be set to the current DOS values.)


   24.1 Applying changes

   As each file is processed, its EDIT mode display line is displayed,
   allowing you to monitor UPDATE's progress through the directory.  If a
   file's display line is not yet shown, nothing has been done to that file.

   After each file has been processed, EDDY checks to see if you have pressed
   a key.  If so, updating will be suspended.  All processing for the file
   being worked on will be completed, but no work will start on the next file.

   When UPDATE has been suspended, it may be resumed by pressing [Enter] (or
   [^Enter], if you want to change the way timestamps on any further copied
   files are treated).  If you press [Esc], EDDY returns to EDIT mode, leaving
   intact any requests for changes not yet processed by UPDATE; these changes
   may be undone if desired, or you may UPDATE them later.

   UPDATE does Deletes and Destroys first.  After deletions, a second pass is
   made to apply any other requested changes.

   If there are errors during UPDATE processing, (read or write problems,
   e.g.) EDDY reports the error as indicated by DOS and suspends the UPDATE at
   that point.  You may resume the UPDATE or return to EDIT, as you choose.

   After a successful UPDATE, pressing any key returns to EDIT.  If the key is
   one of EDDY's commands, it will be acted on.

   EDDY v.7c User's Manual   Copyright (C) 1987-93 by John Scofield  page  84



   After an UPDATE, any files moved or deleted from the working directory will
   be shown grouped together at the end of the directory display, rather than
   in their original locations before the UPDATE.

   If there are more files in the directory than can be displayed by EDDY,
   files deleted or moved will not be shown; instead, additional files from
   the working directory will be displayed.


   24.2 Print a Record of Your Changes - [Alt+p]

   While EDDY is waiting for confirmation to proceed with an UPDATE -- i.e.,
   after you have pressed [Enter] once, and before you press it a second time
   -- you may tell EDDY to print the changes as they are made.

   Press [Alt+p] to print.  Pressing [Alt+p] again turns printing off.

   You may also turn printing on during the UPDATE by pressing [Alt+p].
   Printing will begin with the next change.


   24.3 Target Capacity Check

   EDDY checks to be sure there is enough room on the target directory disk to
   satisfy any COPY or MOVE requests you may have made before starting the
   update.  If there is, EDDY proceeds as described above.

   However, when there is not enough room, you'll see the following messages:

                              Not enough room on X:
                              Bytes needed: nnnnnnn
                              Can't COPY/MOVE files

   "X:" is the target disk drive.  The number of additional bytes needed is
   calculated from the file sizes in the working directory and the cluster
   size of the target directory disk, and takes into account that EDDY does
   deletions first while updating.

   To make room on the target disk, you must delete or move files occupying
   clusters equal to the total "bytes needed".  (Most files' sizes are not
   even cluster multiples, but the space allocated to them by DOS is.)

   When there are changes requested in addition to the copies and/or moves,
   this message will also be displayed:

                          [Enter] to apply other UPDATEs

   If you decide to go ahead, requested changes other than copies and moves
   will be done, but files selected for copying or moving will be ignored.

   There are some situations in which the displayed summary of changes in disk
   space used may be inaccurate.  In some cases, EDDY may run out of disk
   space at some intermediate stage during COPY/MOVE operations, even though
   the summary indicates there is enough space.  This may happen in two
   situations.  First, when all of these conditions occur:

    1) Two or more files, for which there are files with the same name in the
       target directory, are being copied or moved.
    2) Some of the files from the working directory use more clusters than
       their namesakes in the target directory, and some use fewer.
    3) The big files are copied or moved before the small ones.

   In this case, all free space could be filled before space is freed by the
   copying or moving of the smaller files.  If this happens, just resume the
   UPDATE by pressing [Enter].  When the UPDATE has completed, the files that
   were not copied will still be tagged.  UPDATE again to copy those.

   A second situation that can cause the computed space requirement to be
   inaccurate is when copying is done with TAB expansion (see Section 11.3.1).
   TAB expansion (using [Alt+2] thru [Alt+8]) results in a file larger than
   the original.  As EDDY does not scan the file first to count the actual
   number of TABs in the file and calculate the number of additional bytes
   that will result from the TAB expansion, it is possible to run out of space
   on the target disk.

   24.4 Error Recovery

   If a read error is encountered on a disk during a COPY or MOVE operation,
   EDDY offers three alternatives:

     1 - Write a sector of "#" bytes in the new copy of the file in place of
         the sector that cannot be read.  The new copy will be the same length
         as the original.  All data which was in disk sectors that did not
         have have a problem will of course be copied intact.

         To see where the errors were, you might do a FIND on a string with
         several "#"s in a row.  (EDDY writes a full sector, minus 4 bytes, of
         "#"s -- the "#"s are preceded and followed by a CR,LF pair.)

     2 - Skip the sector entirely, and write the next good block immediately
         after the previous block in the new copy. This obviously results in
         a new copy that is shorter than the original.

         When this alternative is used, there is nothing in the new file to
         indicate where sectors have been deleted.

     3 - Abort the copy/move process. In this case the DOS error code will be
         displayed, and no new copy will be produced. EDDY will continue with
         any other updates that may have been requested for other files.

   After an update where choice 1 or 2 has been selected, the message
   displayed for the file(s) involved will be "copied(?)" or "moved(?)", to
   indicate that the new copy is not exactly the same as the original.  Also,
   the date and time on the new copy will always be the current date and time
   in this case.

   If multiple errors occur on a file, all will be treated in the same way,
   according to the alternative you select when the first was encountered.

   25.  EDDY's Default Settings are Lousy!

   You can't please all of the people all of the time.  With this in mind,
   EDDY is designed to be easy to "tailor" to your taste in several ways.

   EDDY can be customized, creating a new copy of EDDY.COM with the various
   colors, options, controls, etc.  set the way you like them.


   25.1 Customizing - "EDDY/0"

   To customize, execute EDDY with option /0 (i.e., enter "EDDY/0") and use
   the normal commands available in the program to set the options, etc.  When
   you have everything set up the way you want it, press [Enter].

   You'll see a display of the various features that may be customized, to use
   as a final checklist.  Press any key to clear this display, and then tell
   EDDY to create a new copy of itself with the settings you have selected, by
   pressing [Enter] or [^Enter].  Normally, EDDY puts the current date/time on
   the new copy; if you want the old timestamp on the new copy, use [^Enter].

   When you customize, your working directory must contain the version of
   EDDY that is to be customized (which must be the same as the version that's
   executing), and it must be named "EDDY.COM".

   The customizable features, and the ways to set them, are:

    1. Screen colors (see Section 25.2)
        - use [Alt+r]  (note: [Alt+r] valid only during customizing)

    2. Options (see Section 2.3)
        - select via [Alt+o] or from the command line

    3. COPY/MOVE/DELETE Controls (see Section 10)
        - select via [Alt+c]

    4. Sort sequence (see Section 1.4.1)
        - use [Alt+d], [Alt+e], [Alt+h], [Alt+n], [Alt+s], [Alt+u] or [Alt+i]

          NOTE: If you use any of the above sort commands, then sorting
          by date/time when using a timestamp filter is not automatic.

    5. Default action for [Alt+w] and [Alt+t] (see Section 5.3.3)

    6. Default point-and-shoot command (see Section 14.2.2)
        - use [Shift+F8], and enter desired command

    7. Attribute filter (see Section 17.1)
        - use [Alt+a], or from the command line, "+xx"

   EDDY v.7c User's Manual   Copyright (C) 1987-93 by John Scofield  page  88



    8. Command key used with left mouse button (see Section 2.1.2a)
        - use [Alt+m], then press key for desired command

    9. Left- or right-handed mouse (see Section 2.1.2b)
        - use [Alt+m], then press right mouse button

   10. Mouse sensitivity (see Section 2.1.3c)
        - use [Alt+Shift+m], then move left or right

   11. LOOK mode bit-stripping, line-wrapping and TAB default settings
        (see Section 8.2.3)
        - in LOOK mode, use [Alt+b], [Alt+l] and [Alt+number], respectively

   12. Hex/ASCII toggle key (see Section 8.2.1)
        - in LOOK mode, [Shift+Tab] allows selection of the key to be used

   13. Auto-scrolling speed (see Section 8.2.2)
        - in LOOK mode, use [^PgUp]/[^PgDn]

   14. Enable/disable absolute sector patching feature (see Section 21.3)
        - answer question: "Allow disk PATCHing by sector in new EDDY (y/n)?"

   15. Identify compressed disks permanently (see Section 21.6)
        - answer question: "Is <x:> a 'compressed disk'...(y/n)?"

   When customizing, no editing, copying, patching or other changes to the
   disk can be made.  The only purpose for this mode is to let you set things
   the way you want them, and then make a copy of EDDY with those settings.

   The customized version will be written to the working directory, and will
   be named "EDDY.COM".  The original copy of EDDY will be renamed "EDDY.OLD".

   During the process of creating the new, customized EDDY.COM, there could be
   error conditions such as bad spots on the disk which cause the process to
   abort; if this occurs, you may see an error message referring to "EDDY.NEW"
   (e.g., "Error writing EDDY.NEW").  EDDY.NEW is the name given to the new
   copy during the customizing process, until it has completed without error;
   only then are the files renamed as described in the preceding paragraph.

   The messages "Where's EDDY.COM?" or "Incompatible EDDY.COM", mean EDDY.COM
   is not in your working directory, or the version that's there is not the
   same as the version that's executing, respectively.

   25.2 Rainbow Selection - [Alt+r]

   In "customize" mode only, the [Alt+r] command is available to allow you to
   select the color combination for EDDY that best suits your monitor and
   preferences.  [Alt+r] displays the following:

                             SELECT SCREEN COLORS

                           For next color on  Press
                           -----------------  -----
                           Headings            [h]
                           Text body           [t]
                           Cursor line         [c]
                           Window borders      [w]
                        [Alt+F1] for menu/HELP colors
                         (Upper case for prev color)

                       [Enter] when you like the colors

   Pressing any of the indicated letters changes the color of the corres-
   ponding part of the display, cycling through all the available colors as
   you press repeatedly.  Upper case letters cycle in the opposite direction.

   When the colors are the way you want them, press [Enter].  Those colors
   will then be used with the new, customized copy of EDDY you create.


   25.3 Customizing by PATCHing

   It is also possible to customize some features of EDDY by using EDDY's
   PATCH capability -- [F4] -- directly on EDDY.COM.

   25.3.1 DOS Prompt String

   EDDY modifies the DOS prompt to end with "Exit>" when you use the DOS Gate-
   way, [F9], to remind you that an EXIT command is eventually needed.  If you
   don't like this, or if you'd prefer some other display, PATCH EDDY.COM
   beginning at offset 00000008 (hex).  In an unmodified copy of EDDY, you'll
   see the string "Exit$g" in this location, followed by a hex byte of "00".

   If you want no change to the DOS prompt, change byte 00000008 to hex "00".
   If you want to use a different prompt, you may PATCH up to six bytes
   (00000008 - 0000000D) with the string you want to use.  Following the last
   byte of your string, PATCH one byte to "00" hex, to terminate the string.

   25.3.2  Data Error Indicator

   When EDDY finds data errors on a disk during a COPY operation, the bad
   sectors may be written out to contain all "#" bytes.  If you PATCH the byte
   in EDDY.COM at offset 00000006 to any other value, that value will be used
   as the bad sector filler character.

   EDDY v.7c User's Manual   Copyright (C) 1987-93 by John Scofield  page  90



   25.3.3  I Don't Mind a Little Flicker

   EDDY displays RAM (in LOOK mode) with a constant update of the screen
   between keystrokes, in order to allow you to watch what's really happening
   there; i.e., some locations, such as the system clock, are constantly
   changing.  However, updating with this frequency causes a lot of screen
   flicker if a Color Graphics Adapter is used.  Most people find this very
   annoying, and so this "real time" display isn't normally done with a CGA.

   However, if you REALLY want to try this, PATCH the byte in EDDY.COM at
   offset 00000007 to anything other than "00" hex.  Have an aspirin ready.


   25.3.4  Don't Confuse [F3] and [Enter]

   If you don't like the fact that [Enter] acts like [F3] when there are no
   pending changes for UPDATE (as described at the end of Section 8.1), patch
   the byte at 00000005 to anything other than "00" hex.


   25.4  How Do I Get Rid of the *$#^&! "UNREGISTERED" Message?

   That's an easy one: Register!  See Section 26.2 for details.

   If you have already registered a version earlier than EDDY v.7a, drop me a
   line and I'll send you the latest version, registered in your name.

   If you have registered EDDY v.7a or later, you may patch the registration
   data into the new copy of EDDY, as follows:

        1.  Press [F3] to LOOK at your registered copy of EDDY.COM.  Write
        down the value found in the 6 bytes of data beginning at offset
        00000025 (00000054 in version 7a, 00000055 in 7b).

        2.  Press [F4] to PATCH your new copy of EDDY.COM, beginning at offset
        00000010, with your name -- exactly as it appears when you QUIT from
        your old, registered version.

        3.  PATCH the new copy of EDDY.COM beginning at offset 00000025 with
        the 6 bytes of data you found in step 1.

   Your new copy of EDDY will now display the "Registered to:  (your name)"
   message when you run it.  If not, you have probably made an error in one of
   the above steps.  (The name used in step 2 must correspond to the 6 bytes
   used in step 3; otherwise, "UNREGISTERED" will be displayed.)

   If you prefer not to bother with these steps, I'll be glad to send you (the
   registered user) the latest version, registered in your name, for the cost
   of handling and distribution (see Section 26.2 for current cost).

   26.  Distribution and Support / Disclaimer

   If you have not yet done so, please read the "DISCLAIMER" that appears at
   the beginning of this file.  In part, that disclaimer means there is no
   representation that EDDY will do ANYTHING, whether or not the author or the
   documentation states or implies that it will.  Similarly, there is no
   representation that the program will NOT do anything harmful or annoying.
   Whatever it may do or not do, the author is not responsible for the
   results.  The person using EDDY bears all risk as to the quality and
   performance of the software, and the consequences of using it.

                            USE EDDY AT YOUR OWN RISK!


   26.1 EDDY is NOT Free and NOT Public Domain!

   Although EDDY is distributed in this way, it is not free. It is also
   protected by copyright, and has not been released into the public domain.

   EDDY is shareware.  This means you are free to make copies, pass copies on
   to anyone else who may be interested, and take a reasonable time to "try
   before you buy" (I consider something on the order of 30 days to be
   "reasonable").  You are, however, expected to honor the "buy" obligation if
   the "try" is satisfactory.

   Copies of the program may not be sold for more than the cost of the medium
   they are copied on, plus reasonable handling charges.

   EDDY and this User's Manual may be copied ad lib provided the author's
   copyright notice and disclaimers of warranty are reproduced in full.

   26.2 Registration

   If you have registered an earlier version of EDDY, refer to Section 25.4.

   If you find EDDY to be useful and satisfactory after a reasonable trial
   period, and you continue to use EDDY, then you should register, either by
   credit card (see Section 26.2.1) or by sending your registration fee of
   $25.00 to the address shown when EDDY exits (see Section 26.2.2).

   The low registration fee entitles you to technical support as described
   below (see Section 26.4), to receive one free upgrade, subsequent updates
   at cost of handling and distribution (US$6.00 in the Asia/Pacific region,
   $10.00 elsewhere), and to the satisfaction of knowing you have done "the
   right thing".  Also, EDDY stops nagging you.

   When you register, you will receive the latest version, registered in your
   name.  This does NOT count as your free upgrade; you are still entitled to
   to a free upgrade at a later date, as new releases become available.

   EDDY will (gently) remind you if your copy is not yet registered.  However,
   all versions, registered or not, are fully functional -- not "crippled" in
   any way.  All features are available to everyone.

   Multiple-copy (site) and network-use registrations available at a discount,
   depending upon the number of copies involved.  Prices available on request.

   26.4 Technical Support

   Technical support is guaranteed to be available to any registered user for
   at least six months from the date of registration.  In practice, support is
   available for an unlimited time; only if circumstances (e.g., illness) make
   it impractical to continue would support ever cease.

   In the unlikely event you (as a registered user) have a problem with EDDY
   (not a bug, surely!), if you take the trouble to report it, I'll try to
   solve it.  And I'll get back to you with a fix, if possible.

   With any problem report, please include the following information:

    1. Version number of your copy of EDDY (as shown on the logo
       which is displayed when you exit from EDDY)

    2. Level of MS- or PC-DOS you are using

    3. Any resident programs being used -
       - listings or copies of AUTOEXEC.BAT and CONFIG.SYS are very helpful!

    4. As complete a description of the problem as possible -
       - what did you enter on the command line?
       - what commands did you use just before the problem occurred?
            (the last 4-5 keystrokes, if possible)
       - how was EDDY's output different from what you expected?
       - IMPORTANT! what were your settings for EDDY's...
            ...options?
            ...copy/move/delete controls?
            ...attribute or timestamp filters?
       - what customization, if any, have you selected (per Section 24)?
       - [PrtSc] screen printouts before and after the problem (if possible)
       - any other information that seems relevant

                                  Why Use EDDY?


   With EDDY around, you can eliminate many of the small, special-purpose
   utilities which are so indispensable to the non-EDDY user.  So as a bonus,
   you get to free up some disk space -- or at least, get back some of what
   installing EDDY consumes.

   The current EDDY is a greatly-improved version of the program reviewed in
   "MicroCornucopia", "Computer Language" and "PC Sources" magazines.  Some
   quotes from those reviews...

                         "The interface ... is elegant."
                  "...clean, easy-to-use, well-written program."
              "...quality of product we've seen from Peter Norton."
       "the commands are extensive, the written documentation is excellent"
                     "EDDY ... offers some uncommon features"

   EDDY has an intuitive, convenient interface for the common operations, such
   as disk/directory/file management, file viewing, etc.  Most of the things
   you frequently need to do take only a keystroke or two.  But EDDY also
   addresses a number of problems which arise less often but are more
   difficult to solve, if possible at all, with other utilities.

   EDDY has the latest, up-to-date, "buzzword" features, too:
    -  Pull-down menus
    -  Context-sensitive HELP
    -  Mouse support
    -  "Prune and Graft"
    -  "Point and Shoot"
    -  Configurability
    -  LAN support
    -  (and of course, "user friendliness" and "ease of use")

   Complete understanding of the examples below may require using EDDY, or
   (horrors!) reading some of the User's Manual.  However, I hope these will
   interest you enough that you'll give EDDY a try.

   EDDY v.7c User's Manual   Copyright (C) 1987-93 by John Scofield  page  a2



   Consider...

   ....Have you ever installed a new package and wondered what it was doing to
   your disk (watching the "busy" light blink), and then been unable to find
   the new or changed files?  Many programs create "hidden" files, in
   directories of their choice, on your disk.  You can find them by using
   EDDY's "Where's That File?" function combined with attribute filtering.

   Enter:  "eddy/w +H", and EDDY will search the whole disk for hidden files.

   ....Or maybe you'd like to know whether any new files were created or any
   of your files were changed by the program you just ran at (say) 9 PM on
   Sep. 14, 1988.  If you enter:
                           eddy/w/h ">09/14/88 08:59p"
   EDDY will find the files, wherever they are, hidden or not.

   ....You don't have to worry whether you should be copying files from A:  to
   B:, or from B:  to A:, nor whether there's room for all the files you want
   to copy.  EDDY will tell you if there's not enough room before starting the
   copying, and warn you before copying a newer file over an older one.

   ....Did you ever lose a file because your only copy was on a disk that
   somehow developed a "bad spot", and couldn't be read?  With EDDY's COPY
   ([F5]) command, you can at least save all the GOOD data that's left,
   leaving out only the part of the file that's actually in the "bad" sector.
   So you don't have to key in all that data or text again!

   ....Want to know the differences between two directories?  EDDY will TELL
   you, not just display the directories for you to compare to one another, if
   you press [Alt+Shift+F3].

   EDDY will report whether a file is in the other directory or not; if it is,
   the relation between the timestamps -- newer, older, same, or even same
   timestamp but different size -- will be displayed as well.  You can stop to
   look at either file's contents, compare the data in the two files, copy,
   move, patch or delete them, and then continue on with the next file.

   ....You can also do the directory comparisons, and file copying, deleting,
   etc., based on the results of those comparisons, in batch mode.  Great for
   routine backups and directory cleanups!

   ....EDDY's string-finding capabilities are powerful and easy to set up.
   You can find strings in one or more files (including binary files) -- even
   hyphenated words continued from one line to the next -- and you can use
   strings with a mixture of hex and ASCII if you want.  There's also a
   similarly powerful "FIND and REPLACE" capability.

   You can even find what ASCII strings may be lurking in a binary file:  use
   a FIND for "??????", for example, and EDDY will show you all ASCII strings
   of 6 bytes or longer.

   EDDY v.7c User's Manual   Copyright (C) 1987-93 by John Scofield  page  a3



   ....Are you annoyed by the extra command line prompt generated by DOS when
   you run a batch file?  You can use EDDY's PATCH function to truncate the
   batch file, deleting the final, line-terminating bytes (usually 3:
   carriage return, line feed and "right arrow") at the end of the file.  With
   these bytes gone, the extra prompt won't be generated.  With big batch
   files, who knows?  You might even save a "K" or so of disk real estate, if
   your file was just over a cluster size boundary.

   You can chop bytes off the front or back of any file and you can add bytes
   -- for example, ^Zs -- at the end of any file.  Or you can expand all TAB
   characters in a file to the equivalent number of spaces (0 - 8, as you
   choose).

   ....Have you ever wanted to read or modify a file of text that was created
   by WordStar (tm), but that's not the word processor you use?  Hard to work
   with, wasn't it?  Well, with EDDY, you can not only read it easily on the
   screen, but you can convert it to pure ASCII, so you can use your favorite
   editor or word processor on it if you want.

   ....Would you like to send entire disks by modem, rather than just files?
   EDDY lets you copy an entire disk -- boot sector, FAT, directories and all
   -- to a file.  You can then compress the file, send it, and the receiver
   can recreate an exact copy of that disk (if he has a copy of EDDY, too!).

   ....If you're running short of space on disk, even the amount of space used
   by the subdirectories themselves can be significant.  A directory always
   keeps all space that was ever allocated to it, even if all the files have
   been deleted.  EDDY will tell you how much space your directories occupy,
   if you turn on option /D.

   ....When you have a long list of files that you want to process (say, you
   want to MASM most -- but not all -- the .ASM files), and you don't want to
   type in the commands one-by-one, the normal thing to do is build a
   multi-line batch file (or one with "FOR" statements) and execute it.

   With EDDY it's easier; just display the directory containing the files,
   (press [Alt+w], and enter "*.asm").  Then "Ignore" the ones you don't want
   ([Alt+F7]) and use the "Point-n-Shoot" capability ([Shift+F9]).  Have a
   look at the EDDY.USE file included with this package to get a better
   picture of the power and potential of "Point-n-Shoot".

                          ==============================

   If you know of programs that do things easier or better than EDDY, please
   let me know, so I can stop making dubious claims (or maybe improve EDDY).
   On the other hand, if you find some more neat things to do with the
   program, or have any ideas for enhancements, I'd like to hear about them.

                           What Does That Message Mean?

   The purpose of this Appendix is to explain some of EDDY's error messages
   which may not be completely self-explanatory or clear from their context.
   Messages are listed alphabetically.

   When these messages are displayed on the screen, they are followed by a
   reminder that more information about why the message appeared and what, if
   anything, you should do about it, may be found in this Appendix.

   If you find some other messages EDDY produces that need clarification,
   please let me know, and I'll include them in the next update.
                          ------------------------------

   Can't adjust sensitivity
        An error has been returned by the mouse driver.  Probable cause is a
        non-Microsoft compatible mouse being used.

   Can't find COMMAND.COM
        After searching the DOS environment, EDDY has either failed to find
        the "COMSPEC" variable, which tells where to find COMMAND.COM, or has
        tried to find COMMAND.COM where COMSPEC said it was, but couldn't.

        You won't be able to do any DOS Gateway or Point-n-Shoot operations,
        but other EDDY commands will work correctly.  When you quit EDDY,
        though, you'll have a problem when DOS can't find COMMAND.COM either.

   Can't move to current target
        You can't move a directory to a directory subordinate to it.  For
        example, you can't move C:\UTIL to C:\UTIL\MISC; you could, however,
        move C:\UTIL\MISC to C:\ if you wished.

   Can't patch this file
        You have pressed [F4], but EDDY cannot get "write" access to the file.
        This is not just a read-only file; in that case, EDDY would ask first,
        and then remove the read-only status so that patching could proceed.

        This may occur on a network, if the file is part of a non-DOS file
        system, such as UNIX, and you don't have permission for write access.

   Directory recall set
        You have pressed [Shift+F10], selecting the current working directory
        for possible "recall".  If you later press [Shift+^F10], this
        directory will again become the working directory.  If you press [F10]
        or [^F10], you will quit EDDY with this directory as the DOS default.

   Directory entry (y/n)?
        You have pressed [Alt+d] to request an area of disk or RAM to be
        displayed as though it were a directory entry, or [Alt+s] to jump to
        the cluster on disk pointed to by that entry.  EDDY doesn't think it
        looks much like a directory entry, he'll do as you ask if you insist.

   DOS version problem
        This message appears if you execute EDDY under a DOS version earlier
        than 2.0, or if you try to rename a subdirectory or sort/shuffle and
        rewrite a directory but are using a level of DOS earlier than 3.0.

   Duplicate name
        When this occurs while trying to rename files, it's pretty easy to
        figure out what the problem is.  When it happens when you're trying to
        copy files, though, it can seem strange.  In this case, it means that
        there's a subdirectory in your target directory that has the same name
        as the file you want to copy -- and so it can't be copied there.

   EDDY.AUX problem
        Much of EDDY's major functionality is stored in the EDDY.AUX file, as
        a set of 5 separate overlays.  If this file can't be located, or is
        found to be corrupt, or is a different version than EDDY.COM, there
        really isn't much useful that can be accomplished.  Most times, you
        might just as well hit [F10].  However, in case you have EDDY.AUX
        tucked away in some non-normal directory, you can recover.  Make that
        your working directory, press [F1] (or any of a variety of other keys)
        and EDDY will discover EDDY.AUX and happily continue.

   File not found. [Ins] to rename.
        You probably pressed a key by mistake, causing EDDY to go into speed-
        search mode for a matching filename that wasn't there.  If what you
        really wanted to do was rename the file, either press [Ins] to turn on
        renaming for that file, or set Option /F ON for all files.

   Memory corrupted!
        When EDDY temporarily gives up control to DOS for Gateway or Point-n-
        Shoot functions, a checksum of EDDY's memory area is computed and
        recorded.  It is computed again when EDDY regains control.  If there's
        a difference, some process that has been executed outside of EDDY has
        written to memory that belongs to EDDY.  EDDY terminates immediately,
        without attempting to restore any paths, colors, fonts, etc.

   No target. Delete all (y/n)?
        You have set the COPY/MOVE/DELETE Controls to specify that the files
        in the target are to be compared with those in the working directory,
        and the result used to determine which files will be tagged for
        DELETE.  But there is currently no target directory.

   Not enough memory
        This may appear when trying to use the DOS Gateway or Point-n-Shoot
        functions, and there is not enough memory to load the requested
        program.  It may also occur if EDDY returns from executing one of
        these functions, and finds that there is not enough memory available
        to continue (and so EDDY terminates).

        You might also see this message when you try to rewrite a sorted
        directory to disk.  It means there isn't enough room in memory for all
        of the directory entries plus workspace for the sort process


   Not supported for this disk
        There are several conditions that can produce this message:
        1. The disk is larger than 32 MB, and the version of DOS being used
           can't handle it.
        2. The disk is a remote drive, accessed on a network, and you are
           attempting some low-level operation, such as sector patching.
        3. EDDY has received conflicting data regarding the disk format.  The
           program always cross-checks this data by calling combinations of
           BIOS and DOS functions, so that all critical data is treated to a
           "second opinion".  If there is disagreement, no low-level access
           will be attempted by EDDY.

   Path name too long
        This one can really be puzzling (some users have reported it as a
        bug).  When you have a path with a long chain of subdirectories, EDDY
        may refuse to move to a directory, giving this message.  It means DOS
        can't get to the directory, even though it's there.  This can happen
        if you rename a directory with a longer name, and the resulting path
        is longer than 64 bytes.  It can be even more obscure if you are using
        a SUBST'ed disk, so that the path doesn't look too long; however, DOS
        uses the total effective length, after expanding the SUBST path.

   Press key for primary mouse button
        EDDY is waiting for you to select -- by pressing -- a key to define
        the command to be executed whenever you subsequently press the primary
        (normally, the left) mouse button.

   Same disk
   Same disk. Set new target (y/n)?
        You have tried to copy, or prepare to copy, an entire disk, plus
        format information added by EDDY, to a file on that same disk -- 5
        quarts won't fit in a gallon jug.

   Size shown in directory incorrect
        This occurs if EDDY copies a file, and finds the size of the file is
        different from the value shown in the directory.  It is not the result
        of anything EDDY did, but is detected by EDDY.  Running CHKDSK will
        correct the discrepancy; finding what caused it may not be so easy.

   Timestamp frozen
   Timestamp unfrozen
        When the timestamp is frozen, it will remain set to the same value,
        and that value will be used whenever [=] is pressed.  When it's
        unfrozen (or has never been frozen), the current DOS date and time
        will be used when [=] is pressed.

   Unable to complete directory move
        Refer to Section 12.2 of this document

   Unable to complete directory rewrite
        Refer to Section 12.2 of this document

   Unsure if files open in this directory. Continue (y/n)?
        EDDY uses some undocumented data structures within DOS to check
        whether any files are open in a directory before rewriting it in the
        new sequence.  This is because corruption can occur if there are open
        files.  If EDDY finds that the data doesn't appear to be valid, and
        therefore is unable to check for open files, this message will be
        displayed.  If there are no files open, answer "y"; if there are,
        answer "n".

   WARNING!  Memory allocation changed
        When EDDY temporarily gives up control to DOS for Gateway or Point-n-
        Shoot functions, the amount of free memory is recorded.  If the same
        amount of memory is not available when EDDY regains control, you've
        most likely run some program which has TSR'd (terminated and stayed
        resident).  Although this is not usually a problem that affects EDDY's
        operation, it will probably cause trouble when you finally quit, as
        there are likely to be "holes", or unusable areas in memory that can
        only be eliminated by rebooting.  If you can remove the TSR program by
        using the DOS Gateway, you should do so to avoid problems later.  If,
        however, so much memory has been taken that EDDY can't continue, you'll
        see "Not enough memory", and EDDY will terminate.

   WARNING! Patching here is hazardous. Patch (y/n)?
        Patching in areas of a disk from the boot sector to the end of the
        root directory can really mess things up if you aren't completely sure
        of what you're doing.  This is where all the formatting information,
        boot mechanism, File Allocation Table, etc.  are stored.  Just to make
        sure that what you're about to do is really what you WANT to do, EDDY
        asks you to confirm that you want to proceed.
