Dove III 1. DoubleTake Professional Features It's a side by side (actually, one on top of the other) file-compare program to locate differences in any files, particularly list of changes between versions. See Appendix A, What's New, for all of the enhancements in Version 2.0. Note: This program was previously released under the name GoodLook. It was renamed DoubleTake to provide a more direct indication of its function. Upon the addition of the advanced features in Version 2.0, DoubleTake was renamed DoubleTake Professional. Advanced Design Features for quick, easy and powerful compares. DoubleTake Professional contains many features to make your compare session simpler, and more useful. Use the Tutorial Files provided for hands-on experience. Here are key design features and how they could be used: Find Next Mismatch. This feature automatically searches both files from the current cursor positions and stops when there is a difference between the two files. Ignore Blanks/Characters. This feature directs DoubleTake to ignore any characters you specify. Most of the time it will be white space (e.g., blanks, tabs), but any character (or range of characters can be ignored. Align Files. This function allows you to manually or automatically re-synchronize the two files. If you have located a mismatch and wish to find where the files are once more in agreement, use the Align Files function to quickly locate the spot and move the correct file forward or backward. Find String. If you are searching for a particular section of a file, use this function to quickly locate the string in either or both files, either forward or backwards. Block Commands. Mark any block and write it to a CLiP file at any time. This is useful to capture changes from an old version of a program which may have been left out of a later revision. Just CLiP it out and import it when you next use your programming editor. Keypad simplicity. The functions you should most use are grouped around the keypad. The cursor/line movement keys, the Find Next Mismatch, for example, are located on or next to the keypad for quick and easy scrolling through your files. DoubleTake Professional Features: Compared lines show on the middle screen lines for direct comparison. Pop-up Menu selections or single keys to invoke options. Page 2 DoubleTake Professional Built-in directory routines allow you to select a file if you don't enter the names on the command line. You can even View a file in the directory, to see if it's the correct file, prior to loading it. Wildcard (*) can be used for second filename for simplicity (e.g., DT file.prg *.bak loads DT file.prg file.bak). Load new file on-the-fly while inside DoubleTake. Choice of three scrolling modes: Parallel or Opposite or ZOOMed. Highlight modes for the two compared lines include: Normal, Reverse video and Flashing. Fully configurable options: Colors, Type of Scrolling, Hex/ASCII Mode, etc. Find Next Mismatch function key to locate the next spot where the file lines differ. The search can be interrupted at any time by pressing any key. The first mismatch found is shown highlighted. Hex mode shows any file (even binary) with option to display non- printing chars (ASCII 1-31) and Graphics characters (ASCII 128-255) or to show them as periods (similar to Debug). Two Hex Modes to show a file in Debug style (24 characters on a line) and in full 80 column mode. WordStar mode to strip the high bits from characters before displaying them. (Can be entered on command line or toggled while viewing a file. Ignore All Blanks function to allow comparing files while ignoring different spacing between them. Selectable Ignore Characters to allow you to customize the characters you want DoubleTake to Ignore. ASCII Chart reference available while choosing Ignore characters. Help available at the press of [F1]. Configuration file presets can be saved to disk. Full DOS path support. DoubleTake will search your existing path to find its configuration files. Simple, intuitive file movement using the keypad and assorted keys. Alternate keys are also available if you prefer to use the Function Keys. You can scroll the files independently or together. In Hex mode the files are fully scrollable forward and backward. Align files function--While searching for mismatches, you can have DoubleTake attempt to re-align the files. The Align Files function works well in conjunction with the Find Next Mismatch function to discover all differences between files. Print Screen toggle. To prevent accidental Print Screen, PrtSc is toggled off at startup. If you wish to print a screen, toggle PrtSc back on at any time. Zoom Feature--You can zoom either file up to full screen. Single file view mode available from the command line. EGA/VGA supported: DoubleTake uses any number of lines found Invoke the 43/50 line mode from the command line or Toggle between 25 and 43/50 line while viewing. Shell to DOS capability allows you to stop and execute DOS commands ant then return to the exact spot in DoubleTake. 2. Running DoubleTake Professional. DoubleTake Professional is named DT.EXE for ease and speed of use. (Rename it to any filename you choose, but do NOT rename the help file, DublTake.HLP. or the Configuration file, DublTake.CNF) DoubleTake Features DoubleTake Professional Page 3 NOTE: Ensure the name doesn't conflict with other programs in your path. For example, if Norton's DiskTest.EXE (also named DT.EXE) is visible in your path, it may run instead of DoubleTake, depending on which subdirectory occurs first in your path. Just change the name of DoubleTake to any other name to accommodate this conflict. Of course, if you use DoubleTake more often, keep the short name DT.EXE and rename the other, conflicting program. a. Memory Management. DoubleTake Professional tries to use all available memory for faster file processing. If enough memory is not available, DoubleTake will not continue, but will exit with the following message: This is not enough memory to run DoubleTake: Total Memory Available is only xxxxxx bytes. DoubleTake requires a minimum of xxxxxK free to run. Goodbye, and thank you for choosing DoubleTake . . . The xxxxx entries will show the actual memory you have available when DoubleTake attempted to run. Free additional random access memory (RAM) and try to run DoubleTake again. (1) File Buffer Sizes. DoubleTake has a minimum size for the file buffers. If more than the minimum is available, DoubleTake will use up to approximately 65,000 character buffers for each file. (2) Shell to DOS Memory Requirement. To temporarily go to DOS to perform tasks requires a minimum of approximately 75,000 bytes of free memory above that used by DoubleTake. If there is not enough memory, DoubleTake will so indicate. As you shell to DOS, DoubleTake will inform you of the amount of free memory you have (in Kilobytes). Note: DoubleTake frees the file buffers before shelling to DOS and reloads them upon returning the DoubleTake (by typing EXIT at the command line). This means only about 200 Kbytes of memory is held by DoubleTake. Depending on the size of buffers used at startup, DoubleTake may free up as much as 200K to 300K for your use while in DOS. When in ASCII mode and toward the end of a very long file, expect delays as the ASCII file is reloaded. (3) DoubleTake File Picker Memory Requirement. DoubleTake must have room to load at least 20 files or it will exit with a "not enough memory" error message. When the File Picker is invoked (either by running DoubleTake from the command line with no files provided, or by using the New File Function inside DoubleTake (by pressing the [Alt-N] key). If DoubleTake runs out of memory while finding the filenames, it will add " and more" as the last filename entry on the screen, to indicate that there was insufficient memory to gather all files. Running DoubleTake Page 4 DoubleTake Professional b. Command Line arguments. Type at the DOS prompt: C:\DT [<File1>] [<File2>] [/w][/x][/4] and press the [Return] or [Enter] key. The arguments following DT are as follows: <File1> and <File2> are optional filenames (if none is entered, DoubleTake will prompt for filenames). /w is an optional WordStar flag to strip the high bits from characters before displaying them (the unusual characters you see at the end of every word in a WordStar file which was created in the Document mode.) Note: The parameters may be in any order -- DoubleTake will interpret them correctly. /x flag reverses the ASCII/Hex mode called for in the configuration file. For example, if you have configured DoubleTake to start in Hex Mode, the /x flag starts DoubleTake in ASCII mode and vice versa. /4 flag reverses the 43/50 line mode which is specified in the configuration file. For example, if 43/50 line mode is specified, the /4 switch starts DoubleTake in the 25 line mode. If the configuration specifies the 25 line mode, the /4 switch will start DoubleTake in the 43 line mode on an EGA-capable display card and in the 50 line mode on a VGA-capable display card. On a machine with a CGA only display card, the /4 switch will be ignored. Note: DoubleTake will detect if your monitor is already in 35, 43 or 50 line mode and will automatically use the current setting (unless you toggle the mode with the /4 switch on the command line). c. Filenames on the Command Line. Enter a fully qualified filename on the command line for each of the two files you wish to compare. A fully qualified filename consists of the drive, path and filename for the file. For example: C:\MYPATH\MYFILE.EXT consists of Drive : C: Path : \MYPATH\ and Filename : MYFILE.EXT. If you omit the drive or path, DoubleTake assumes the file is on the currently logged drive and in the currently logged path. For the second of the two files, use a combination of wildcards and pathnames to simplify the entry of the filename. The asterisk [*] wildcard can be used Running DoubleTake DoubleTake Professional Page 5 for the entire filename or for just the filename or just the extension. You can avoid having to type the same filename.ext by simply by entering a pathname for the second file, if the filename and extension are the same. For example: C:\DT Filename.typ B: will compare Filename.typ and B:Filename.typ. C:\DT Filename.typ C:\NEWPATH\ will compare Filename.typ and C:\NEWPATH\Filename.typ. Notes on pathnames. Paths MUST end in backslash (\). If you enter a path without a backslash as File 2, DoubleTake assumes you mean a filename, not a path. C:\DT Filename.prg *.bak will compare Filename.prg and Filename.bak. C:\DT Filename.prg b:\path\*.bak will compare Filename.prg and b:\path\Filename.bak Wildcards for filename 2: Both * and *.* mean use the File 1 filename and extension along with any new drive\path entered. For example: DT C:\WP\Filename.TYP D:\ and DT C:\WP\Filename.TYP D:\* are equivalent to: DT C:\WP\Filename.TYP D:\*.* and will compare C:\WP\Filename.TYP and D:\Filename.TYP. Note: DoubleTake will not accept a wildcard filename (e.g., *.bak) as the first filename. Using other DOS conventions. DoubleTake recognizes the "." and ".." as legal paths. For example, C:\UTIL\DT Filename.TYP ..\ will compare C:\UTIL\Filename.TYP and C:\Filename.TYP d. DoubleTake Files. At startup, DoubleTake searches for files needed to install your custom settings and provide on-line help. (1) Support Filenames. DoubleTake searches for the following support files: a DublTake.CNF. This file contains your customized settings for DoubleTake colors, preferences, view modes, Hex or ASCII modes, and so Running DoubleTake Page 6 DoubleTake Professional forth. See the Configuration Section for more information on tailoring DoubleTake to your specific requirements. b DublTake.HLP. This file contains the help screens shown when you request assistance by pressing the [F1] key. c DublTake.ASC. This file contains all 256 ASCII codes which are available to you when you enter specific characters to ignore or characters you want DoubleTake to treat as End of Line characters. (See the Configuration section for information on how to change these codes.) (2) Search Locations. DoubleTake searches in several locations as follows. If DoubleTake fails to find its files in the first location, it looks in the next, then the next, and so forth. a DoubleTake first looks at the currently logged location. This is the location from which you ran DoubleTake. For example, if you ran DoubleTake from the root directory on the C: drive, DoubleTake would look there first for its support files. b DoubleTake then locates where DT.EXE exists and checks there for its support file. c DoubleTake then checks to see if you have established a path in an Environmental Variable. Use the following command (at the command line or in a batch file, such as AUTOEXEC.BAT) to establish an environmental variable with the DoubleTake path where the support files are located: SET DT=C:\UTILITY\ You can check the value of this variable at any time by typing SET and pressing [Enter]. d DoubleTake finally searches any path you have defined (with the PATH=PATH1;PATH\2; command, either at the command line or in a batch file such as AUTOEXEC.BAT). e. Getting a Filename inside DoubleTake. If you don't enter the filename on the command line, DoubleTake will prompt you for one. If you can't remember the filename--don't panic--just press the [F1] key to get a complete listing of the files in the current directory. If you wish to change directories, just place the highlighted cursor on the desired subdirectory or parent directory and press [Return] to move to that directory and see the files.

To jump directly to a filename, press the first letter of the filename (A to Z). The cursor will go directly to the first filename starting with that letter. Press the same letter again, and the cursor moves to the next filename starting with that letter. (b) Pre-Viewing Files. If you are not sure what file you wish to compare, use the preview option to look at the files. Just put the cursor on the file you wish to preview and press [Alt-V] to examine the contents. (c) Duplicate Filenames. If the same filename is entered for both File 1 and File 2, DoubleTake will alert you and prompt you for a new file 2. Running DoubleTake Page 10 DoubleTake Professional Note: DoubleTake uses all available free memory to collect the filenames using the File Picker. If there are more filenames on the disk than can be collected in the available free memory, and more will be displayed as the final filename entry. Enter DoubleTake with more free memory to allow loading of more filenames. 3. DoubleTake Operating Modes and Characteristics. a. DoubleTake File Viewing Modes. (1) Two File Mode: This is the normal mode for DoubleTake. Unless you tell DoubleTake to view only one file, DoubleTake expects two filenames which it will display one above other as described below. (2) Single File Mode (also known as Zoom mode): This allows you to look at a single file using the full screen. You can invoke DoubleTake in the Single File (Zoom) Mode by simply entering a single filename on the command line or by pressing [Z] while viewing two files, and choose either [1] or [2] for the file to Zoom. (3) Character/Position Cursor. The cursors in all modes serve two purposes: 1) to show where you are in the file (used as the beginning location for Find Next Mismatch, Find String, and Align Files functions) and 2) they highlight and identify a character, showing its hexadecimal or decimal value. a Searching from the Cursor. DoubleTake begins searching from the current cursor position in each file. When it reaches a character difference between the two files, DoubleTake stops with the cursor pointing to the difference. If the difference is a minor one, just move the appropriate cursor to re-align the files and press the Find Next MisMatch key again. If the difference in the files is great, try the Align Files or Find String function to locate the next point of coincidence. b Scrolling with the Cursor. Use the Cursor Left or Cursor Right keys to move the cursor in the files. In Two-File mode, the [<] key moves the cursor back toward the beginning of File 1 while the [Ctrl-<] key moves the cursor back toward the beginning of File 2. Similarly, [>] moves the cursor forward toward the end of File 1 while the [Ctrl->] key moves the cursor forward toward the end of File 2. As you scroll forward or backward in the file, the lines will automatically scroll forward or backward. For example, at the beginning of the file, as you move to the end of a line, the next press of the Cursor Right key will cause the display to scroll forward to the next line in the file, with the cursor at the left of the display. Similarly, if you press Cursor Left, it will scroll back to line one, with the cursor at the end of the previous line. Note: The [Shift] key can be used instead of the [Ctrl] key if desired. c Dual Scrolling Mode. If [Scroll Lock] is ON (i.e., the [Scroll Lock] light is lighted) the [<]/[>] keys will scroll both file cursors backwards or forwards, respectively. If not in Dual Scrolling Mode, press Running DoubleTake DoubleTake Professional Page 11 the [Shift] and [Ctrl] keys together while pressing [<]/[>] to move both cursors together. (4) ASCII Mode. This mode is often the most useful for comparing two files which consist of only printable characters such as letters, numbers and punctuation. Source code files from high-level languages fall into this category (such as C, Pascal, dBase or BASIC (when the BAS program has been saved with the ASCII switch) and FORTRAN, to name a few) as well as most DOS BATch files and DOS CONFIG.SYS. This allows you to view a file much like you would in a word processor or full-screen text editor. DoubleTake recognizes line ends and displays each line at starting at column 1. If a line is longer than the viewable 80 columns on your monitor, scroll the screen to the right and left using the [Tab] and [Shift-Tab] keys. Figure 4 shows a file being viewed in Single File mode. Note: An easy way to tell whether you are in ASCII or Hex mode is to see if the Horizontal Scroll indicator is present. This indicator, on the right side of the last line, line shows which file will scroll horizontally when the [Tab] key or [Shift-Tab] key is pressed. This indicator is only present in ASCII mode. ╒[Line: 1 ][ File 1: C:\UTILITY\TUTORFIL.ONE ]═══════════════[Value: $20]╕ File with Indent 2.. This file has a standard indent of 2 spaces... ..

At this point, DoubleTake will automatically shift to Hex mode. With about 480K free when DoubleTake is loaded (i.e., all buffers will be created at maximum size), this shift to Hex will only occur when the average line length drops below about six characters per line. This minimum may be smaller if less than full memory is available. If the average line length drops below this minimum (at any time while new portions of the file are being loaded), DoubleTake will automatically shift into Hex Mode, but remain at about the same location. (5) Hex Mode. Hex mode is most often used with files which consist of non-printable characters, such as .COM or .EXE files and some word- processor files (such as WordPerfect, Microsoft Word, etc.). Hex mode displays both the character and the Hex or Decimal value of the character. Choose from two different formats of Hex display -- use [X] to toggle between the two Hex modes. (a) Hex 24-Character Mode. This mode displays a file in much the same way of DOS's Debug.COM program does (see Figure 6). The values on the DoubleTake Operations DoubleTake Professional Page 13 left are the hexadecimal values of the printed values on the right. (The cursor also helps to match values since both the hexadecimal value and the printed character are highlighted in this mode.) ╒[Byte: 0 ][ File 1: C:\UTILITY\TUTORFIL.ONE ]═══════════════════════════╕ 20202020 20202020 20202020 202 ┌───────────────────────────────────────┐ Fi 6C652077 69746820 496E6465 6E7 │ ┌─0D0A──────┐ le with Indent 2.. 20202020 20202054 68697320 666 │ │ ┌────────┐ ├────────────────────────┘as a s 74616E64 61726420 696E6465 6E7 └─┴──┤Carriage│ │ 63 tandard indent of 2 spac 65732E0D 0A0D0A28 426F7468 2066696C │Return │ │ 69 es...

This mode displays a file by displaying the printed version of all ASCII characters, 80 columns wide (see Figure 7). The value of the character at the cursor on the highlighted line is displayed on the window frame, at the upper right corner for File 1 and at the lower right corner for File 2. Note: In the 80-Characters Hex Mode, the value may be displayed using either Hexadecimal or Decimal numbers. Press [Alt-H] to toggle between the two. Hex numbers are shown preceded by a dollar sign [$20], while Decimal numbers are preceded by a backslash [\032]. This mode is useful for displaying a wholly ASCII file which has very few or no line ends. Suppress other than ASCII printable characters (punctuation, upper and lower case letters, etc.), by turning the Display Special Characters toggle off. By pressing [D], you will toggle between displaying all special characters and showing them as periods [.] or as space characters [space].

For example, with File 1 zoomed, use the [Home], [Up Arrow] or [PgUp] keys to scroll File 1 back one line in the file. (2) File Line Numbers and Byte Counters. These indicators show the current location of the highlighted cursor in the file being viewed. As you are performing the Find String, Find Next Mismatch and Align Files functions, the Line/Byte counter will increase/decrease to show the current location being examined. The Line Number/Byte Counter is positioned at the top left of the File 1 window and the bottom left of the File 2 window. (a) ASCII Mode. In ASCII Mode, the line numbers represent the actual line number of the line in the file you are viewing. When you find mismatches, make a note of the line number to find it when you go into your editor. (Lines longer than 80 characters are not visible until you use the [Tab] key to scroll the display to the right.) When the [Alt-#] key is pressed to toggle to the Byte mode, the indicator will show the specific byte in the file currently highlighted by the cursor. DoubleTake Operation Page 16 DoubleTake Professional Note: The cursor stays in the screen window as you scroll. For example, if you scroll the file to the right far enough, the shorter lines will disappear to the left. When the highlighted line has been scrolled past the end of the line, the Value Indicator will show -->LineEnd, indicating the cursor is past the end of the line and no longer on a value on that line. If you are displaying Line numbers in the file, the correct line number will be indicated. If you are displaying byte numbers, the Byte Number indicator will be blank (because it is not on and byte in the file). (b) Hex Mode. The byte counter for each file keeps track of the file pointer. As you move the cursor in either file ([Ctrl-<], [Ctrl->], [<], [>], [Shift-Ctrl-<] or [Shift-Ctrl->]), the byte counter will be incremented or decremented to reflect the current file pointer position. (3) Print Screen Indicator. The PrtSc indicator, a Paragraph symbol [ ] indicates whether the Print Screen function is ON or OFF. If [ ] is highlighted (or ON), then Print Screen is enabled (i.e., if you press [Shift-PrtSc] the screen will be printed). If not highlighted, then Print Screen is OFF. DoubleTake starts with PrtSc OFF to prevent you from accidentally pressing the Print Screen while you are scrolling through the files using the keypad and the gray [*] (asterisk) key (also the [Shift- PrtSc] key on some keyboards). (4) WordStar Mode Indicator. This indicator shows WS:[O]n or WS:[O]ff. The brackets around the "O" remind you to press the [O] key to toggle this mode between On and Off. (5) Display Special Characters Indicator. The Display Special Characters Indicator displays a highlighted [D] to indicate that Display Special characters is on, and a normal [D] to indicate that Special Characters are to be displayed as periods [.] or as spaces [space]. This mode can be used in conjunction with the Wordstar Mode to make the display more readable. As you press [D] the display will shift between the three styles. Choose the one which is clearest for your needs. (6) Blank/Character Ignore Indicator. The Blank/Character Ignore Indicator will display a highlighted [B] to indicate that DoubleTake will Ignore those characters you've chosen to ignore while performing certain functions. If the indicator is not highlighted [B], then all characters will be evaluated when performing compare functions. See the Configuration section to see how to add other Ignore Characters to be ignored while performing the Find String, Find Next Mismatch or Align Files functions. (7) Vertical Scroll Methods. There are two methods for scrolling through the files: Parallel Scrolling and Opposite Scrolling. You can toggle (by pressing the [S] key) between these modes at any time while you are viewing the files. Note: The compared lines (at the center of the screen) can also be changed to your own choice of colors to make the file character cursors more easily distinguished from the rest of the lines. See the Configuration section for more details. DoubleTake Operations DoubleTake Professional Page 17 (a) Opposite Scrolling. Figure 9 shows the way Opposite scrolling works. As the files scroll, both scroll into and out of the center. With the compared lines right above each other, it's easy to find differences in the lines. Use the Find Next Mismatch key to locate the next mismatched line, then find out how it differs by one-on-one matching. Notice that graphics displays or boxes (in the compared source files) will appear in reverse order in the upper window. If this is annoying, press [S] to switch to the Parallel Mode, or Zoom the file to full screen temporarily. ╒[Line: 1][ File 1: C:\UTILITY\TUTORFIL.ONE ]════════════════[Value: $20]╕ (This file has randox x's scattered to allow you to find.. 10 .. │ 9 Shi │ Left] ar ┌─────────────────────────────────────────────┐ 8 [Ri │ /Left] a │ Pressing the [Down Arrow] key moves both │ ght/.. 7 Pre │─────────┤ cursors forward in both files, meaning the │ 6 wit │ elpful c │ cursors move closer to the end of the file. │ .) .. 5 (Bo │ files co │ The lines will then scroll in the direction │ nual, .. 4 .. │ ┌───┤ of the arrows and the lines will increment │ 3 │ T │ to the next line. │ 2 │ └─────────────────────────────────────────────┘ Lines: 1 ════╪════1 │ ═╪════2════╪════3════╪════4════╪════5════╪════6════╪════7════╪════╡ │ File with Indent 4..

This Scrolling method will ensure any boxes or graphics displays in File 1 will appear normally. (8) EGA/VGA Mode: You will be able to tell the type of Screen mode you're in by the appearance of the files on screen. In the EGA/VGA (43/50- line) mode, you will see 19/22 lines per file in the Two File Mode and 39/45 lines per file in the Single File Mode. If you have your EGA/VGA card in the 43/50 line mode when DoubleTake is run, you do not need the /4 switch -- DoubleTake will automatically use all 43/50 lines. You may only specify 43/50 line mode, however, when entering the argument from the command line mode, but DoubleTake will find and use the total number of lines available, for any of the following: 25,35,43 or 50. While viewing a file, you may also toggle between the 43/50 and 25 line modes using the [E]GA/VGA option. Note: Even if you opt for normal 25 line viewing, DoubleTake detects the EGA card and sets the Video Speed to Fast.

This feature allows you to go to directly to Configure or Help with a single keystroke, or directly to the pop-up menu of choice without scrolling left or right. You also can scroll left or right to other pop-up windows by pressing the [<]/[>] keys. Note: In Pop-Up Menus with more than one choice, you may use the [^]/[v] keys to move the pointer (the small arrowhead next to the entry [ ]), and press [Enter] when the pointer is on your desired selection.

Align Files Function. DoubleTake Professional includes a powerful capability to realign files which have become out of step with each other. There are three ways to accomplish a realignment. (1) Manual Align. To manually align the files, simply move one or both file cursors until you have reached a point in both files that are identical. If the following automatic alignment methods do not work you may have to resort to manually aligning the two files. (2) Semi-automatic Align. DoubleTake Professional will search for you and attempt to locate a common area between the two files. When you press [Alt-A] you will be allowed to change the Align Files parameters (see Figure 18).

For the majority of your alignment actions, first try the Automatic Align Function, [A]. (3) Automatic Align. Automatically Align files. This function uses the default align file settings and automatically searches for a match. The search begins initially forward. If not match is found, a search backward is done. If no match is found DoubleTake swaps the Search/Move file with the Match file and tries again, forward and backward. If there is a match, one or both file cursors are relocated to the new locations. Otherwise the files are returned to the locations before the search for a match was started and a message appears indicating there was no match found. (Figure 25). d. Find String Function. This function works in either Hex or ASCII mode. If you are in the Two-file mode, you will have the option of choosing which file to search for the string, either File 1, File 2 or both. Press [Enter] for the default value, search [B]oth files. You will then be asked if you want to ignore UPPER/lower case while searching. Press [Enter] to select the default value shown. If you choose [Y], then the string will match any combination of UPPER or lower case for the whole search. Now enter the string to find as shown in Figure 26.

Backward searches continue to the beginning of the file. Note: If all searches fail, the cursor(s) will remain in the location at the start of the search. If you wish to find other than normal ASCII values (letters, numbers, punctuation), you can search for any code by entering the string portion of inside double (or single) quote and the other values in Hex or Decimal. For Hexadecimal values, use the Hex value preceded by a dollar sign [$]. $0D is the Hexadecimal code for Carriage Return, for example. For Decimal DoubleTake Operations DoubleTake Professional Page 27 values, use a backslash preceding the decimal value. \13 or \013 is the Decimal code for Carriage Return. For example, if you wanted to look for a string with a Carriage Return/Linefeed in the middle, enter the following: "This string" \013 \010 "is on two lines." or "This string" $0D $0A "is on two lines." DoubleTake will then look for This string followed by Carriage Return and Linefeed, followed by is on two lines. Note: If you are searching for characters which are in the set of characters you want DoubleTake to ignore, the string will not be found. Ensure you have Blank/Character Ignore set to OFF (i.e., the [B] is not highlighted) when you are searching for non-printable characters. You must enclose the string in either single or double quotations marks if you wish to include Hex or Decimal codes in the search string. If you wish to search for single or double quotes, either enclose them in the opposite quote marks (e.g., '"Hi"' or "it's") or enter them using their Hex or Decimal values (e.g., \034 "Hi" \034 or 'it' \039 't'). Interrupt the search at any time by pressing any key. e. DoubleTake Main Screen Keys. The definitions of the function keys are shown at the bottom of the main screen. To get the definitions of the other keys, use the Help key [F1] or [?]. Use the numeric keypad (or optionally, the Function keys) to scroll File 1, File 2 or both. If you get lost, just press [F1] or [?] to get a complete key list. Additionally, the Pop-Up Menu key, [/] provides a reminder of the main screen shortcut key to use on each pop-up menu selected. Note: The keypad keys are all close together for all functions, making the keypad easier to use than the function keys. Both are provided for your convenience. Key Definition [F1] or Help key. Press this key to get a list of all active keys when [?] in the Main Screen as well as in the Configuration Screen. Note: When you press the Help key, you skip the Commercial when you press any key, if you have a registered version. If you have not registered, the commercial will appear when you start or leave DoubleTake, and every time you get Help. In a registered version, press [F1] twice to see the commercial (and the name and serial number of the Registered User.) DoubleTake Operation Page 28 DoubleTake Professional Key Definition [/] Pop up the Menu/ShortCuts system. The commands listed here are all available from the pop-up menu commands (with the obvious exception of the scrolling keys -- it would not be reasonable to use a 2 or 3 key pop-up menu choice to accomplish what the scroll keys do in one keystroke). See the Pop-Up Menu section for a detailed description of this menuing system. [Alt-A] Align files manually. This key allows you to try to bring File 1 up to align with File 2 or File 2 up to align with File 1. [A] Automatically Align files. This function uses the default align file settings and automatically searches both files, both directions, for a match. Use manual align [Alt-A] if you wish to change the align setting on-the-fly. [B] Blank/Character Ignore toggle. This toggles whether or not the Find Next Mismatch or Find String routines skip the Blank/Ignore Characters. This allows easier compares of files which differ mainly in the spacing between the words in the two files. Normally, the characters to ignore will be at least the [Blank] and [Tab] characters. The Configuration section shows how to change the characters to Ignore. [C] Configure DoubleTake. See the Configuration Section for details on changing colors and options. [Alt-D] Exit to DOS. This option allows you to temporarily jump to DOS to do anything would like (except: DO NOT LOAD any Memory Resident Software (also know as Terminate and Stay Resident (TSR) software) while you are in this DOS Shell). Just type the word EXIT to return to the exact place you left in DoubleTake. This is a simpler and faster way to perform DOS tasks than quitting and restarting DoubleTake. [D] Display special characters toggle. This toggles between displaying the printed characters with ASCII codes between 0 and 31 and 127 and 255 or displaying a period [.] or a [space] for those characters. If the periods on the end of a line are be distracting, then toggle to display a [space] for each special character. This is functional in all modes. [E] EGA/VGA Mode. This allows you to toggle the EGA/VGA card between the 25 and 43/50 line modes. When you press [E], if you have an EGA or VGA card in your computer, you will be automatically toggled to the 43 (or 50) line mode if you are in the 25-line mode. If you are in the 43 (or 50) line mode, you will be toggled back to the 25 line mode. If you do not have an EGA or VGA adapter, you will hear a Bell when you press [E]. Note: As expected, this only works on machines which have the EGA or VGA card installed. There is no check to see if there is an EGA/VGA monitor attached, so you need to take care that you do not shift to a mode which is not supported by your monitor. DoubleTake Operations DoubleTake Professional Page 29 Key Definition [F] Find a String. This allows you to search for a string in either Hex or ASCII Mode, using either simple strings (which may or may not be enclosed in quotation marks) and strings combined with either Hex or Decimal character codes (when including Hex or Decimal codes for a search, you must enclose all strings in quotes.) Search can be forward in file or backward toward beginning of file. [Alt-F] Repeat previous Find. This key uses the same settings previously given in a Find String command. You will be asked to confirm (or make changes to) the search string. When the string is correct, press [Enter] to accomplish the search. [Alt-H] Toggle between Hexadecimal and Decimal display of the value at the cursor. In the 80 column Hex mode or the ASCII Mode, the Value indicator shows the current ASCII code for the character highlighted by the cursor. If the value is shown with a dollar sign [$] in front of the numerals, the value is shown in Hexadecimal ($00 to $FF). If not, the number is the Decimal value (0 to 255) with a backslash [\] preceding the value. [Alt-N] Load a new file or files. Use this to change File 1 or File 2 or both. If you loaded only one file from the command line, use this command to load the second file if needed. Also useful to compare multiple files to the same file. You will have the same options (direct type-in or the internal Directory File Picker) as when you initially loaded the files. [O] WordStar Mode On/Off toggle. When on, the high bit is stripped from each character. This converts the Horizontal double line box from " " into "MMMMMMM" but it is mainly useful to correct the last character of most words in a WordStar file. [Alt-P] Toggle PrtSc On/Off. When DoubleTake starts, PrtSc is disabled -- pressing [Shift-PrtSc] will do nothing. This allows you to freely use the [Left-Shift] (or [Right-Shift] instead of the [Ctrl] key) with the cursor movement keys to move either file one page at a time. If you do desire to do a PrtSc, you must first press [Alt-P] to turn PrtSc back on. You can tell the status of PrtSc by the PrtSc indicator in column 71 of the Key Status Line. If this symbol is highlighted (i.e., if the symbol is ON), then PrtSc is enabled. Pressing [Shift-PrtSc] now will send a copy of the page to the printer using the DOS Print Screen function. When this symbol is not highlighted (i.e., off), [Shift-PrtSc] does nothing. [Q] Quit. This key will exit DoubleTake and return to DOS, after asking you if you really want to quit. [S] Scroll Mode. This toggles between the Opposite and Parallel scrolling modes. See the description of the two types of scrolling in the previous section. (This key not available in Zoom Mode.) DoubleTake Operation Page 30 DoubleTake Professional Key Definition [T] This will return both files to Top of File as when you first loaded DoubleTake. [Tab] Scroll the display to the right (the line seems to move to the left) to allow viewing the rest of long lines (ASCII Mode only). Use the Configuration function to change the amount of the scroll right/left. The amount of the display has been scrolled is shown on the outer borders of each file window (e.g., top line for File 1, bottom line for File 2). [Ins] The [Ins]ert key changes the file to horizontally scroll. The Horizontal Scroll Indicator on the bottom line indicates which file will currently be scrolled when you press the Horizontal Scroll Keys. The [Ins] key selects Both [ ], Top (or Zoomed File) [^] or Bottom [v]. [Shift- Use the [Left-Shift] key to scroll the display to the left (the Tab] line seems to move to the right) to allow viewing the beginning of a line (ASCII Mode only). Use the Configuration function to change the amount of the scroll left. [Right- Return the display to the first column (the beginning of the Shift- line) for the selected file (see the [Ins]ert key above to see TAB] how to change the selected file. [Alt-#] Toggle between the Line Number and Byte Number while in the ASCII Display Mode. When in the Line Number display mode, the indicator shows each line of the file, from line 1 to the last line of the file. When in the Byte display mode, the indicator shows the exact file byte located at the cursor, from 0 to the last byte in the file. The Byte display mode functions the same in Hex or ASCII mode. Note: In ASCII display mode, if you scroll the screen the right past the end of a line, the line number will be shown in the Line Number display mode, but the indicator will be blank in the Byte Number display mode, because the cursor is not on a character of the file. [X] Toggle between the 24-Character and 80-Character Modes. The position of the cursor in the file does not change when you toggle between modes. [Alt-X] Hex/ASCII Mode Toggle. This toggles between the ASCII mode and the Hex modes. When in Hex mode, you will see the Hexadecimal equivalent of the character along with the printed character, similar to the Debug format. See the earlier section discussing the types of Hex modes. DoubleTake Operations DoubleTake Professional Page 31 Key Definition Note: When DoubleTake changes from Hex to ASCII or ASCII to Hex, expect the file cursors to remain in the same location in the file. The one exceptions is when you have scrolled the screen to the right past the end of the line containing the cursor. If you then change to Hex, DoubleTake moves the cursor to the last character on the current ASCII line. Also note that changing to ASCII is more complicated than changing to Hex, so expect the process to take a little longer. [Z] Zoom feature. This allows you to zoom either file up to full screen. Use this for a more complete look at one of the files and then return to the dual window mode to continue the compare. When you press [Z] you'll be asked which file to Zoom. Press [1], [2], [N] or [Enter]. Pressing [N] or [Enter] will default to None. Press [1] to Zoom File 1 and [2] to Zoom File 2. When you have a file Zoomed, all keys for either file will work. For example, when you have File 1 Zoomed, the normal movement keys, [Home], [End], [Ctrl-Home], [Ctrl-End], move around the file, as well as the [PgUp], [PgDn], [Ctrl-PgUp], [Ctrl-PgDn], [Up/Down Arrow] and gray [+/-] keys. The filename and line numbers for the Zoomed file remain in the same location as in the dual window mode, however. Note: When you use DoubleTake in the single file mode, you are in the Zoom Mode and the file is considered File 1. (The [Z] key is not available in the Single File Mode.) Note: The following keys are used to mark the beginning and end of a block in a file and write the block to a CLiP file. The keys are grouped together according to function, with each key identified to the file which is controlled. In the One-File Mode or Zoomed mode, either of the two keys will perform the desired function. For example, if File 1 is Zoomed or in One File Mode, either [Ctrl- B] or [Alt-B] will mark the beginning of the block in the file. [Ctrl- Mark the beginning of the block in File 1 and File 2 B] or respectively. In Zoomed or One File mode, either key will set [Alt-B] the beginning of the block. [Ctrl- Mark the end of the block in File 1 and File 2 respectively. K] or In Zoomed or One File mode, either key will set the end of the [Alt-K] block. [Ctrl- Clear all markers in File 1 and File 2 respectively. C] or [Alt-C] [Ctrl- Write marked block out to a CLiP file for File 1 and File 2 W] or respectively. If a block is not marked, you will be alerted. [Alt-W] DoubleTake Operation Page 32 DoubleTake Professional Key Definition Note: You will be asked to choose a destination Filename for the CLiP file. Enter any filename or use the File Picker to choose a filename. (DoubleTake defaults to a CLiP filename using the viewed filename with an extension of CLP. If the CLiP filename is the same as the file you are viewing, the CLP extension will be replaced with CL1.) If you send the marked block to a Printer (such as LPT1 or PRN), you may need to send a printer buffer flush command when you have sent all you wish to the printer (e.g., an ASCII Carriage Return--Code 013 or $0D). On some printers, cycling the printer Off-Line and back On-Line will flush and print the buffer. Note: In the following description of keys, you will see the terms up/back and down/forward. Think of it as moving the highlighted line up and down the page. Although the highlighted line does not move, think of Up/Back as meaning moving the highlighted line to a previous line on the page and Down/Forward as meaning moving the highlighted line further down the page.

There are two ways to make changes to the DoubleTake configuration file DUBLTAKE.CNF: Invoke DoubleTake's built-in Configuration routine (inside with no file and press [F10] or press [C] from inside DoubleTake and then [W]rite the new values to disk) or (less preferable) Change the file DUBLTAKE.CNF with an ASCII editor (such as DOS's EDLIN.COM, or Sammy Mitchell's outstanding Quick Editor-- QEdit, for example.) The default DUBLTAKE.CNF is shown in Figure 28. 7 Main Screen foreground color (0-15) 0 Main Screen background color (0-7) 15 Help Screen foreground color (0 to 15) 0 Help Screen background color (0 to 7) 15 HiLi Screen foreground color (0 to 31) 7 HiLi Screen background color (0 to 7) False Non-WordStar(tm) Mode Selected (T/F) (prints all, even graphics chars) ASCII Ascii Mode to display files (ASCII/Hex) 80 Characters to Display in Hex Mode (24 or 80) True Ignore characters (T/F).

Except for these lines, all lines consists of two parts: 1) the value in the first column, and 2) the explanation in the second column. All legal values for column 1 are shown at the end of the explanation line in column 2. If you use other than a legal value, DoubleTake will skip that value and keep its default value. Ensure that you keep the spacing on each line identical to the original. Do not rearrange the lines or insert blank lines into the file. If you do, the file will not load correctly and the default values will be loaded. What if I destroy the configuration file? Even if you completely wreck the configuration file, just create a new one with the following steps: 1. Run DT (alone or with a file) 2. Choose [F10] Configure from the files menu (if DT was run alone) or choose [C]onfiguration from the main screen, then 3. Change the values to reflect your preferences, and 4. [W]rite out a new copy of DUBLTAKE.CNF. b. Choosing Your Favorite Colors DoubleTake comes in plain vanilla White on Black to ensure it is readable on any screen, whether it's a monochrome, color or monochrome monitor on a color card. (If you have a color monitor, rename COLOR.CNF to DublTake.CNF to start up in color.) Note: If you are using monochrome video display on a Color Graphics Adapter, and the display is horrible, you might be able to improve it by exiting DoubleTake and, using the MODE.COM program from your DOS disk, typing: A:\>MODE BW80[Enter] ([Enter] is the [Return] key.)

Configuration Mode Key Definitions. The following keys are active while in the Configuration Option: Key Definition [F1] Get Configuration Help. This provides help about the or Configuration Options and the Exit Options. [?] [F] Move to the next color for the foreground colors for normal text. The colors allowed for the foreground are: 0 Black 8 LightGray 1 Blue 9 LightBlue 2 Green 10 LightGreen 3 Cyan 11 LightCyan 4 Red 12 LightRed 5 Magenta 13 LightMagenta 6 Brown 14 Yellow 7 White 15 LightWhite [B] Move to the next color for the background colors for normal text. The colors allowed for the background are: 0 Black 1 Blue 2 Green 3 Cyan 4 Red 5 Magenta 6 Brown 7 White 8-15 Above colors 0-7, flashing (Highlighted Line only) [Ctrl Change the foreground of the highlight color for the compared -F] lines in the center of the screen. See [F] for the foreground colors. [Ctrl Change the background of the highlight color for the compared -B] lines in the center of the screen. See [B] for the background colors. If you set the Background to a color greater than 7, the background will flash. This allows you to set the highlight line to any flashing color you wish. If you do not want flashing, just cycle the background colors back to the 0 to 7 range. [Alt- Change the foreground color of the Help Screen. F] [Alt- Change the background color of the Help Screen. B] [E] Toggle between 25 and 43/50 line mode on cards that can shift (EGA/VGA). The display will immediately shift to the selected mode. At the DoubleTake Main Screen use the [E] Shortcut Key to immediately toggle between the 25 and 43/50 line modes. DoubleTake Configuration DoubleTake Professional Page 41 Key Definition [O] WordStar Mode On/Off toggle. When this Mode is on, the high bit is stripped from each character. This converts the Horizontal double line box from " " into "MMMMMMM" but it is mainly useful to correct the last character of most words in a WordStar file. At the DoubleTake Main Screen use the [O] Shortcut Key to immediately toggle WordStar Mode On/Off. [V] Speeding Up The Display On A Fast Color Graphics Adapter. On many clones, the color card is much faster than the IBM CGA. Because of this you do not need to wait for retrace to write to VIDEO memory. To take advantage of your card's faster speed, use the [V]ideo mode key to toggle to the Fast Video mode. If you see snow when in the Fast mode, you'll need to toggle back to Slow if this snow annoys you. [I] Toggle Display of Special characters. In Hex Mode, you may or may not wish to see the actual value of the character as printed. You may opt for a less cluttered display by choosing the Display as periods option. This displays the characters 1-31 and 128-255 as periods. Toggle again to get the characters back. At the DoubleTake Main Screen use the [D] Shortcut Key to immediately toggle Display Special characters On/Off. [S] Toggle Scrolling Mode. Press the [S] key to toggle between the Parallel and Opposite Scrolling Modes. This option can also be toggled at any point while viewing files and in the Configuration screen. [N] Toggle the Beep on/off. Normally, DoubleTake will beep if you press an incorrect key for the situation. If this annoys you, just turn the Beep Off. [C] Toggle Case sensitivity. The default case sensitivity is used when DoubleTake searches for a string, a mismatch or tries to align files. [1] Choose which file will be the "search from" file and which file or will be the one to "move" forward or back until it aligns with [2] the "search from" file. If you press [1], then DoubleTake will try to find the string at the cursor in "search file" file 2 and search through "move" file 1 to try to find a match. When a match is found, the cursor in file 1 will be "moved" to the spot in file 1 which matches the "search from" file. [R] Choose the Search Direction. When DoubleTake tries to find a match, you may choose which direction for the search. You may choose either Forward, Backward or Both ways. If you choose both ways, DoubleTake will search forward and then backward until a match is found or it reaches the limits of the search distance set. DoubleTake Configuration Page 42 DoubleTake Professional Key Definition [F7] Choose the number of characters in the "search from" file to match. The count will represent the number of characters from the current cursor in the file. Choose a smaller number of characters to have more chances for matches. [F8] Choose the distance to search in the "move" file. Normally, the greater this distance (up to 32000 characters), the more likely a match will be found if there is one somewhere in the file. Be aware that longer search distances result in longer times for matches which are far from the current spot. [A] Toggle between Hex and ASCII. Some files, such as binary files like COM and EXE files, are difficult/impossible to display in DoubleTake in the ASCII mode. If you normally compare two binary files, toggle into the Hex Mode using the [A] key. At the DoubleTake Main Screen use the [Alt-X] Shortcut Key to immediately toggle Hex and ASCII Mode. [H] Toggle between Line numbers and byte numbers. In ASCII mode you have the choice of viewing the file cursor position by line number or the actual byte position of the cursor in the file. Line numbers start at line 1. Byte positions start at byte number 0. At the DoubleTake Main Screen use the [Alt-#] Shortcut Key to immediately toggle Line numbers and byte numbers. [Z] Change the Horizontal Scroll Amount. In ASCII mode, long lines, past the last column on the video monitor can be viewed by Horizontally Scrolling to the right by pressing the [Tab] key. The amount scrolled is controlled by this value. Enter the desired value and press [Enter]. [X] Toggle between the 24 and 80 Character Hex Display Modes. At the DoubleTake Main Screen use the [X] Shortcut Key to immediately toggle 24 or 80 Character Hex Display Modes. [L] Toggle Ignore Blanks/Characters. When comparing two source files, you may be interested in the real differences between the two files, independent of the spacing or formatting characters such as Tabs. Press [L] to toggle Ignore Blanks/Characters On to disregard all blanks and selected characters or Off to do an exact compare. See the following key to see how you can choose just what characters get ignored when you try to Find Next Mismatch, Find String, or Align Files. At the DoubleTake Main Screen use the [B] Shortcut Key to immediately toggle Blanks/Characters Ignore On or Off. [F9] Edit or add to the Blank/Ignore characters. DoubleTake comes configured to ignore Blanks, Tabs, Carriage Returns, Line Feeds and Form Feeds. You may enter any values (in Hexadecimal). DoubleTake Configuration DoubleTake Professional Page 43 Key Definition [F10] Edit or add to the End-of-Line Characters. DoubleTake needs to know what characters will be used to indicate the end of a line in the files you will be comparing. The provided set of End-of- Line characters includes the standard Carriage Return (ASCII 13) and Line Feed (ASCII 10) plus these same codes with the high bit set (as used in WordStar(tm)). Add any other characters if your files uses other than these characters to end a line. The editing is similar to the Edit Ignore Characters above (see Figure 34). ╒[ Enter/Edit Line End Characters ]═════════════════════════════════════════╕ │ │ │ 0A 0D 8A 8D ≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡ │ │ Enter in Hex: 20=Space 9=Tab 0D=CR 0A=LF 0C=FF xx..xx=Range, etc. │ ╘═══════════════════════════════════════════════════════════════════════════╛ Figure 34 Note: DoubleTake recognizes two End-of-Line characters in a row as a single End-of-Line, not two. If your file contains single characters as End-of-Line indicators, then DoubleTake will treat two End-of-Lines in a row as a single End-of-Line character. This should only have an effect on the Line Number indicator. The Byte Number indicator will still indicate the absolute location in the file. [W] Write default configuration to Disk. Use this key to save a copy of your choices in the file DublTake.CNF. When DoubleTake starts again, it will load and set these defaults. After writing to disk, you will be returned to DoubleTake for more file comparison. [Esc] This exits the configuration option, keeping the current settings, back to DoubleTake Main Screen. If this is a temporary change (such as color settings) this will not permanently change the defaults. Use [W]rite configuration to save the defaults.
