VII Compiling compiling instructions I OVERVIEW See REVISIONS section for revisions. DME is an editor designed mainly for programmers. Although it is not a word processor, it does include many word processing features such as Word-Wrap and automatic paragraph formatting. Here is a quick 'features' list: -control language based on a rich command set accessed manually or via arbitrary mapping of keys. (Every key may be mapped to 128 different things via qualifier and mouse keys) -General variables, reference macros as variables, ENV: enviroment variables (1.30C and beyond). -fast visual response (it scrolls quickly)... even faster when BlitzFonts or similar text speedup utilities are installed. -title-line statistics showing your current position in the file, file name, whether the file has been modified or not, etc... -Multiple Windows, ability to iconify windows -Word Wrap and automatic paragraph formatting. -ability to map any KEY or MOUSE BUTTON combination. DME has been designed to allow easy expansion, and I intend to make many future improvments. It has not been designed for user friendliness, but is straight forward if you read this document [care]fully. DME can take any number of arguments. Any argument without a '-' in front of it is considered to be a file. Normally, DME will automatically SOURCE two script files, S:.EDRC, and the .EDRC in your current directory. These files do not have to exist. These script files usually contain mappings and do things (for example, turn on savetabs). FLAGS: -ffilename -source this script file instead of .EDRC -b -normally when multiple files are specified, DME opens them with small windows. This opens them with normal sized windows. -tN -Open the window on scan line N -lN -Open the window offset N scan columns -wN -Make the window N pixels wide -hN -Make the window N pixels high -sN -Own screen has N bitplanes N=0 means workbench screen II KEYMAPPING MOUSE BUTTONS: The mouse buttons and combinations thereof may now be mapped. The default mappings for the mouse buttons are as follows: Left-button: Move cursor to current mouse position Right-button: Iconify window Left-button held down while moving mouse tracks the cursor The iconification features: -Remembers original window size and placement -Remembers placement of iconified window when you re-iconify later. Currently, you will crash the machine if you run out of memory and DME is unable to open the icon window or original window, so be careful. see below for mapping the mouse buttons and mouse movement. KEYBOARD: The rest of the Functional interface for DME is based on key/mouse mappings and a rich command set. Unlike other text editors, any non-qualifier key in DME may have any meaning whatsoever. It just so happens that the default keymappings assign such things as the (return) key to the RETURN function, the (up) key to the UP function, etc... Keys are named by their keycap labels with the following exceptions: the name for Back-Space is BS the name for numeric keypad keys are prepended with an NK, except for the Enter key which is named 'ENTER'. The four cursor control keys are labeled UP, DOWN, LEFT, and RIGHT The three mouse buttons are labeled RMB, MMB, and LMB. NOTES: The normal Amiga mouse has only two buttons, the Left and the Right mouse buttons (LMB, RMB). A properly installed three-button mouse is also supported. You must type commands in lower-case, except for text, which can be either lower or upper case, and for upper-case alpha keys when specifying keymaps (i.e. A and s-a are the same key). The exception is the AMIGA qualifier key, which uses 'A' instead of 'a'(Alt). Each key may be qualified with any combination of CTRL, ALT, SHIFT, AMIGA, or any of the MOUSE buttons. With 6 qualifiers (7 if your mouse has a middle button), you can assign up to 64 (128) different maps to each physical key on the keyboard. The CAPS-LOCK, when lit, is equivalent to SHIFT only for Alpha keys. The AMIGA-ALT (aA) combination isn't very usable since Intuition uses the sequence to duplicate a Mouse SELECT. Other AMIGA sequences are used by intuition for mouse movement and other things. Some other qualifier combinations may not be usable due to other special sequences. Some keys must be mapped by their lower-case keycap. That is, to map the '>' key (USA keyboard), you specify shift dot (s-.) ***EXAMPLES:*** tab tab a-a ALT a A-a AMIGA a sA-a SHIFT AMIGA a s-tab SHIFT tab c-tab CTRL tab ac-? ALT-CTRL ? s-f5 SHIFT F5 nk0 Numeric Keypad 0 cs-nk0 CTRL SHIFT Numeric Keypad 0 L-lmb Left Mouse button pressed L-mmove Mouse moved while left mouse button held down LR-lmb left mouse button hit while right mouse button held down s-. shift . ('>' for USA keyboards) *************** MAPPING MOUSE BUTTONS Mouse buttons serve both as QUALIFIERS and as KEYS. Thus, you can map both normal keystrokes which require a mouse button to be held down: map L-a ((left button and an a)) as well as the mouse keys themselves: map L-lmb ((left mouse key)) note that you had to specify the left mouse button down qualifier L as well as the left mouse button LMB. If you map the left mouse button, and also map a sequence such as left mouse button + a: map L-lmb tomouse map L-a ((hello)) Note that the first mapping will always get executed even if you intended L-a (that is, BOTH mappings would get executed). In order to avoid confusion you might want to UNMAP the system default mapping for the right mouse button (mapped to ICONIFY) if you wish to apply combinations to the right mouse button. MOUSE MOVEMENT is mapped with one or more mouse qualifiers (L, R, M), plus 'MMOVE' for the key. That is: map LR-mmove ((moving the mouse with both buttons held down)) Or how bout capping the characters under the mouse while moving the mouse? map LR-mmove (tomouse if cl (tlate -32)) DEFAULT KEYMAPPINGS: All Printable Ascii keys mapped to their ascii equivalent. BS, DEL, UP, DOWN, LEFT, RIGHT, TAB, S-TAB, and ENTER are mapped properly. These are the default system keymappings. map (a-c) (bcopy) map (a-d) (bdelete) map (a-down) (scrolldown) map (a-l) (while cu (tlate +32 right)) map (a-m) (bmove) map (a-r) (nextr) map (a-s) (bsource) map (a-u) (while cl (tlate -32 right)) map (a-up) (scrollup) map (bs) (bs) map (c-/) (escimm (find )) map (c-]) (ref) map (c-[) (ctags) map (c-1) (goto block) map (c-b) (block) map (c-c) () map (c-del) (remeol) map (c-down) (pagedown) map (c-esc) (recall) map (c-f) (reformat) map (c-g) (escimm (goto )) map (c-i) (insertmode on) map (c-j) (join) map (c-l) (wleft) map (c-n) (next) map (c-o) (insertmode off) map (c-p) (prev) map (c-q) (quit) map (c-r) (wright) map (c-s) (split first down) map (c-u) (unblock) map (c-up) (pageup) map (c-w) (wordwrap toggle) map (del) (del) map (down) (down) map (enter) (return) map (esc) (esc) map (f1) (escimm (insfile )) map (f10) (saveold quit) map (f2) (escimm (newfile )) map (f3) (escimm (newwindow newfile )) map (f6) (saveold iconify) map (f7) (escimm (bsave )) map (f8) (saveold escimm (newfile )) map (f9) (saveold) map (L-lmb) (tomouse) map (L-mmo) (tomouse) map (left) (left) map (R-rmb) (iconify) map (return) (return insline up firstnb down) map (right) (right) map (s- ) (( )) map (s-del) (deline) map (s-down) (bottom) map (s-left) (first) map (s-right) (last) map (s-tab) (backtab) map (s-up) (top) map (sa-s) (unblock block block bsource) map (tab) (tab) map (up) (up) III COMMAND SEQUENCES DME has a rich command set which allows you to embed commands within commands, or specify multiple commands in a row. A command consists of a KEYWORD followed by a FIXED number of arguments (0, 1, 2...). The argument delimeter in DME is a SPACE. Therefore, to embed strings containing spaces as a single argument, you must surround the string with (string) (backsinglequote-string-singlequote). TEXT to be written as if typed is also specified via a string in backquote-quotes. For example: right right (hello) right right (hello) enter down map f4 (right right) map f5 (left left) map f4 ((hello)) Reiterating (because this is important!)... If a command expects ONE argument, then it really does expect a single argument, and any remaining arguments are thought to be the next command... so: map f4 right -right is only one word, so no need for (). map f4 (right right) -we want to map f4 to two rights... we need the () or the second right will not be part of the map. map c-del (repeat cright del) -this is already implimented as REMEOL, but shown here for clarity. Some arguments will eventually be fed through the command interpreter more than once. The MAP command is a good example. When you execute a MAP command, the first run through the command interpreter installs the map string minus a set of quotes. So, if you want to specify text, you must enclose the text in two sets of ((text)) because the map string gets passed through the command interpreter again when you hit the mapped key. Here are some more complex examples: map f4 (right right (hello) left left) *RIGHT* map f4 right right hello left left *WRONG* map f4 (map f4 ((hello))) -the first time you hit F4, it's command is to re-map itself to the TEXT (hello). (gads!). map c-i (repeat tr (( ))) -example of how to embed a space in a map and repeat (goes through command interpreter three times!). An easy way to fool around executing commands or making maps is either to use the ESC key (which enters command mode), or a-S (alt-shift-s), which EXECUTES the current DME line that the cursor is on.... so you can use DME to edit and test your new keymappings. STRING VARIABLES String variables are replaced with their contents. Three specification forms are allowed: $varname - varname can only consist of a-z,A-Z,0-9,-,_ $(varname) - anything not containing a '(' or ')' $`varname' - anything not containing a '`' or ''' Two special variables exist: filename - the current filename scanf - the current scanf'd string (see SCANF below) lineno - the current cursor line number (1 .. N) column - the current cursor column number (1 .. N) Other variables cause a search of three variable domains to find the contents. For example, if you give $DMEFONT: (1) An Internal variable named DMEFONT is searched for. Internal variables are case sensitive. (see SET, UNSET) (2) An Enviroment variable name DMEFONT is searched for. Enviroment variables are NOT case sensitive. (see SETENV, UNSETENV). The 1.3 ENV: is used. (3) A DME keymap or menu definition named DMEFONT is searched for. This allows you to say something like $sa-tab to insert the contents of the shift-alt-tab keymap. (see MAP, UNMAP, and MENU oriented commands). The reason for the other two forms of variable specifiction is to allow one to access strangely named variables (with puncuation and other crap). SPECIAL NOTE: What is wrong with this command? repeat 100 (first ($myvar)) What is wrong is that $myvar is evaluated BEFORE the repeat is executed. myvar might contain characters that would confuse the command specification when. That is, if myvar contained a '(' you could get something like: repeat 100 (fist ((()) which is obviously incorrect. By using \ you can cause $myvar to be evaluated at loop-execution time rather than before: repeat 100 (first (\$myvar)) These kinds of problems can also occur when you do keymaps... you probably do not want to evaluate the variable at keymap-entry time, but rather would want the variable evaluated at keymap-execution time. On the otherhand, this is perfectly allowable: set x (tlate +1) repeat 100 ($x) Which executes the command (tlate +1) 100 times... By NOT surrounding the variable with parens (depends on the situation), the variable is executed rather than inserted as text. SPECIAL CHARACTERS ^ is used to introduce a control character. For example, ^c would embed a control-c. You cannot embed c-@ (ascii code 0). backslash \ is used to override special meanings. The next character is overriden. map c-a ((^l)) -map control a to produce a control l map c-a ((\\\^l)) -map control a to produce a "^l". The first \ overides the second, and the third overides the ^.

If in the middle of a word, move to beginning of current word. WORDWRAP on/off/toggle -Word Wrap mode (related to MARGIN) WRIGHT -move to beginning of next word ------------------------------------------------------------- ------------- More Info on Complicated Commands ----------------- ------------------------------------------------------------- MENUOFF/ON -This command will enable/disable menus. Users who have a whole bunch of MENUADD commands in their .EDRC should note that disabling menus at the beginning will speed up the MENUADD commands. Then reenable menus at the end. These calls are stackable in that if you call MENUOFF, say, twice, it will take two MENUON commands to restore menus. The reverse is not true. CTAGS (c-[) -(1.30B and beyond) Compatible with Aztec's CTAGS program. This command searches for the subroutine name under the cursor in the associated tags file ("tags" in the directory holding the file currently being edited). Also, the file "tags" in directories specified by the special DME path (see ADDPATH and REMPATH) will be searched. If the tag is found, it loads the file the subroutine resides in if neccesary, then WindowToFront()'s the window, ActivateWindow()s it, and GOTO's the line where the subroutine starts. The search within the source file is anchored to the left column. If the file is already loaded, it is not reloaded. This enables a programmer to quickly trace subroutines over an arbitrary number of files. The tags file contains one or more lines of the following format: subroutine-name file-name /^search-pattern (that's a slash and a carrot, then the pattern) -- EXAMPLE of 'TAGS' file: setpen cmd1.c /^setpen( do_up cmd1.c /^do_up( -- SPECIAL NOTE: CTAGS will work even if you are not in the directory containing the file. You can thus place a tags file in the directory containing the files it references, and the filenames WITHIN the tags file need not be a full path. REF (c-]) -(1.28d and beyond). This is a very powerful new command that allows you to bring up a reference to a keyword with a single keystroke. This is useful for programmers who have on-line documentation or fully commented include files. DME opens a window just big enough to fit the reference. NOTE: The new CTAGS command may be more suited to your application. The reference keyword is the alpha-numeric string currently under the cursor. REF will search the file DME.REFS in the directories listed by the special DME path (see ADDPATH and REMPATH). The file must be built by the user and each line has the following format: (keyword) (#lines) (file) (search string in file) OR (keyword) (endstring) (file) (search string in file) Surrounding the keywords with `' or () is optional if the keyword does not contain spaces. keyword -keyword under cursor #lines -number of lines to include from specified file (just a number) file -the file containing the reference material searchstr -search string in file that indicates the beginning of the reference endstring -alternately, the #lines can be a string, in which case a match indicates the end of the reference in the file. Upon finding a successful keyword match the specified file is openned and the seach string searched for. If found, the indicated number of lines (or until a match with the endstring) is placed in a temporary file and a new DME window brought up. The temporary file is then deleted. When looking for matches, the compare is anchored at the beginning of each line in the file. Thus, any spaces in front of the string in the file must be duplicated. T: must be assigned to a temporary directory, usually RAM: See the included example DME.REFS file. The most common things referenced are the autodocs and commented include files. Some modification of the included DME.REFS.* files may be required due to differences in include file and autodoc format. SCANF ctlstr -This is equivalent to the C scanf() function with the restriction that only one conversion is allowed, that conversion being a string. Thus: scanf %s will place the string under the cursor in the variable $scanf scanf %4s The first four chars of the string. scanf %[0123456789] will scan the string while it contains specified chars (e.g. scan a number) scanf %[~,] will scan the string until it finds a ','. The variable $scanf may be used as an argument in any command. Example: (insfile $scanf). NOTE: If using $scanf in a macro, you probably want to precede it with a \ to prevent it from being evaluated at macro-creation time. REPEAT N arg -Repeat (arg) N times. Apart from being a number, N can also be one of: line Current line # (lines begin at 1) lbot #lines to the bottom, including current line cleft column # (cols begin at 0) cright #chars to eol, including current char under cursor tr #char positions to next tab tl #char positions to next back tab Certain commands can abort a REPEAT loop. Specifically, any FIND[R], NEXT[R], or PREV[R] in which the search string is NOT found will abort a REPEAT. Most operations which can go out of bounds, such as UP, LEFT, RIGHT, DOWN, also abort a repeat. Specifying -1 as N causes REPEAT to go on forever (well, actually, 0xFFFFFFFF times) or until an abort. IF [!]condition arg WHILE [!]condition arg IFELSE [!]condition arg else arg If the specified condition is true, execute the argument. For WHILE, the argument is executed until the condition is false (be careful!). the optional '!' inverts the logic. Conditions: # if toggle entry # is SET. there are 256 toggles (0..255) t if On line 1 b if On last line l if At column 0 r if At end of line (spaces below and beyond) m if Text has been modified i if in insert mode x[<=>]# if column position (starts at 1) is (any OR combo of <, =, or >) than some number. Example: x<=20 y[<=>]# if Line number (starts at 1) is (same as for x) cl character under cursor is lower case alpha cu character under cursor is upper case alpha ca character under cursor is alpha-numeric cn character under cursor is numeric c[<=>]# character under cursor is ascii code # (# in decimal) optional conditionals as in 'x' and 'y'. cb cursor within a block Example: simulating an insert mode toggle: ALT-i (not CTL-i) map a-i (ifelse 0 (toggle 0 insertmode OFF) (toggle 0 insertmode ON)) Example: while lower case, map to upper case and move right. map c-U (while cl (tlate -32 right)) Example: Search/Replace all of text. map c-R (escimm (findstr ) escimm (repstr ) repeat -1 nextr) if c<32 ((char under cursor is smaller than 32)) if c<>32 ((char under cursor is not equal to 32)) while !b down ERRORMODE -DME is able to read the error files of two compilers, M2Amiga and Amiga-Oberon. ERRORMODE NONE = No error files ERRORMODE M2 = M2Amiga error files ERRORMODE OBERON = Amiga-Oberon error files If you set the errormode to M2 or OBERON, DME checks if the corresponding error files exists. Then you can skip with FIRSTERR, NEXTERR, PREVERR, CURRENTERR through the error list. READERRS re-reads the error file. IV FILE PARTICULARS No Matter what you set internal tabs to, tabs in disk files will be 8. This allows you to use your favorite tabs stops (mine are 4) and still have your disk files compatible with TYPE, a printer, etc... DME by default doesn't bother to optimize when writing out files and simply uses spaces. If you (SAVETABS on) before saving (or in your S:.EDRC, etc...), DME will attempt to optimize the file by placing TABS in appropriate places. DME will not place any TABS after the first single, back, or double quote is encountered in a line. If this does not cover every situation in your particular application that you want to be *sure* no tabs will occur in sensitive sections, then you should not use (SAVETABS on). It should be noted that since DME removes spaces at the end of the line, editing UUENCODED ascii files will not work for uuencoded lines which end with a space. The nominal fix is to add an extra character after each uuencoded line (anything) in the proper column, which is ignored by the UUDECODE program. The command to save the current document under the default name is SAVEOLD, *not* SAVE. SAVE is not a valid command. This is to prevent people who have not read the documentation from assuming 'save' takes an argument (and screwing up their work). SAVEOLD does NOT take an argument, SAVEAS does. SAVEOLD/SAVEAS do not automatically backup the destination file. If you are working in an enviroment where you are worried about ensuring a viable copy can be recovered if your Amiga crashes in the middle of the save, you can write a macro to save the file into two places. Usually, people backup their working disks so this is not neccesary. Workbench Support: If DME is run from the workbench, it will automatically construct an icon file when you save a document. If run from a CLI, no icon file is generated. V WORKBENCH SUPPORT DME V1.26 and beyond support the workbench in the following way: (1) you can click on the DME icon to bring up DME with the file "unnamed". (2) you can select one or more standard ascii documents which have DME as the default tool. If DME has no knowlege of a text icon, it uses its own. Command line arguments are passed to DME via the tooltypes entries for DME's application icon or via individual document icons. The following format is used: (This is a hack, no?) ARG=flag See the OVERVIEW section for allowed flags. Only one argument per line is allowed (sorry). The tooltypes for the application icon are processed first, then the tooltypes for each document icon are processed before each file is loaded.

Macros, Internal variables, and ENV: enviroment variables may be specified with $varname, $(varname), or $`varname'. -New commands: SET, SETENV, UNSET, UNSETENV (variable support) -REFS window bug fixed I hope (made window slightly too small). -SAVE[S]MAP bug fixed for space mappings -CTAGS doesn't modify the window title if the window is iconified (allows you to make the following map: map <somemap> (iconify ctags) V1.30B Limited release -Kim fixed a bug in splitpath -added CTAGS command... support for Aztec's CTAGS program -added ADDPATH command... special directory paths for DME -added REMPATH REFS no longer searches fixed directories, but looks at the ADDPATH directories. CTAGS also looks at the ADDPATH directories. CTAGS supports arbitrary directory specifications and is intelligent about where to look for the TAGS file. V1.30 RELEASE -a couple small bugs fixed -fixed text bug that sometimes overwrites the right border -added new commands SETFONT (for all of text, static fonts only) IGNORECASE (for searches) -added new commands (AREXX support, Kim DeVaughn) RX, RX1, RX2 -added new commands (by Kevin Speghetti) PUSHMARK, POPMARK, SWAPMARK, PURGEMARK block marker stack PING, PONG text markers (0-9) note: block marks on the stack, ping and pong, do not track text changes (bug). -Many commands will now work while the text window is iconified without having to uniconify it. V1.29E -Fixed low memory bug in do_bomve() again. -Fixed arp file requestor problems. -added ARPINSFILE command. V1.29D -Fixed low memory bug in do_bmove()... V1.29C -highlighted icon window if file modified V1.29B -INLINE FILENAME: added $filename variable. $scanf and $filename can now be embedded anywhere on the command line. - ^x added (control-character), so you do not have to embed actual control characters in your macros. - \ overide added (\^x) produces "^x" instead of control-x, etc... V1.29 RELEASE -Foreign keyboards supported better. -Iconify window is activated rather than not activated. -can keymap keys which normally produce nothing. -blocks are displayed in a different color -can now move/copy across windows -can now resize window while file loading -new commands ARPLOAD ARPSAVE (uses ARP filerequestor if arp.library) MENUADD MENUDEL MENUDELHDR MENUCLEAR MENUOFF MENUON minor bugs fixed, major remodeling of the source (this is what I use my vacation for!) menus: the right mouse button may be mapped only if there is no menu, Else is used as the menu selector. NOTE! It is much faster to surround a set of MENUADD commands in a source file with MENUOFF at the beginning and MENUON at the end. You can also specify menu items as macros in other commands (example: project-save) V1.28h SMALL RELEASE references work better V1.28g SMALL RELEASE Fixed NK0 bug in 1.28f plus keymap problems in 1.28f V1.28f RELEASE Fixed macro bug created in 1.28e... could not specify macros on the command line. V1.28e INTERNAL/BETA New Commands: REF (c-]) -cross reference the word under the cursor and bring up a new window containing a description for that word. See docs above. -The keymapping has been fixed and should now work on any foreign keyboard. -MAJOR ADDITION: () may be used instead of `' to enclose commands. One can enclose the other ... that is, to get the "'" character you can say (this is a charlie's day). V1.28c RELEASE New Commands: CHFILENAME -change default filename for a window RECALL (c-esc) -recall command line (e.g. you make a mistake). Must be used from a keymap, default is c-esc. SCANF -C scanf (single string only). Extract strings from the text for use in any arbitrary command. Command Parser: $scanf -as an argument by itself is recognized to be the extracted string from scanf. Currently, the variable name (after the dollar) can be anything since only one variable exists, but use '$scanf' for future compatibility. -Many Bug fixes (mainly benign bugs) -^C (CONTROL C) now recognized when typed in a window. c-c is mapped to () = no action. -Please look at the revised default keymappings listed in these docs. V1.28 LIMITED RELEASE New Commands : SCROLLUP (a-up) SCROLLDOWN (a-down) Modified Cmds: ESCIMM The execution of commands specified by an ESCIMM is blocked until the user hits return on the ESCIMM command line. BCOPY No longer unblocks the block. -Title bar status line no longer blinks when it changes -Key releases no longer effect operation V1.27 RELEASE -macros run about 20% faster due to hashing of the command table -Maximum # of toggles raised to 256 (see IF/WHILE) -small fixes to the code (nothing major) -child windows inherit tab stops, insert mode, and wordwrap mode -MOUSE BUTTONS AND MOVEMENT CAN NOW BE MAPPED -New Commands: ICONIFY (used to be hardwired. Is now a command) -Extended Commands: GOTO (GOTO END of block) V1.26 Beta, minimal Release -Workbench support -New Command: EXECUTE V1.25 RELEASE -BSAVE does NOT UNBLOCK after saving (switch in functionality yet again) -various bugs fixed (IF, tabs on file save) -New Commands: MARGIN, REFORMAT, WORDWRAP, RESIZE, TOPEDGE, LEFTEDGE, WIDTH, HEIGHT -Command line options added for setting the window size and an optional specified script file (when specified, local .EDRC not sourced). -Enhanced Commands: IF ..more control with conditions, addition of a couple more specifications. JOIN .. functionality slightly changed -keymaps may now be used as macros in other commands. (macros) -New keymaps added to the default set. -Mouse movement cleaned up a little. V1.24 Internal V1.23 RELEASE -S:.EDRC now sourced instead of C:.EDRC -User keymappings now work in COMMAND mode (when you hit ESC). -You can now map the Amiga keys ('A' for Amiga, since 'a' is alt). -Enhanced Commands: IF/IFELSE/WHILE (optional '!' in front of cond) new condition 'cb' 'character is in selected block' GOTO block (goto beginning of block) -NewCommands: PAGESET SAVETABS -Writing TABS (always 8) out to disk to save space now supported. V1.22 RELEASE (BUF FIXES FROM 1.20) -'newfile' fixed V1.21 RELEASE (BUG FIXES FROM 1.20) -iconify and window handling fixed -left mouse button now tracks the mouse. V1.20 RELEASE -bug fixes: bsave now unmarks the block, bdelete now sets 'modified' flag. (other small fixes). -enhancements: overwrite mode status indicator, find, find-replace now completely implemented (yahhoo!!!) -changed commands: FIND NEXT PREV: no longer loop back to the top of file or top->bottom in the case of PREV. DELINE will now delete text on the line if there is only one line of text. -enhanced commands: GOTO REPEAT -new commands: SAVEMAP SAVESMAP TOGGLE SETTOGGLE RESETTOGGLE TLATE IF IFELSE WHILE BSOURCE FINDSTR REPSTR FINDR NEXTR PREVR NEWWINDOW -new keymappings: (see a-s, a-S, f3) -window iconification with mouse menu button. V1.12 RELEASE -cursor is now pen #3 rather than #1. -changeover to AZTEC C, smaller executable. -now maps shift space to a space. -new commands: REMEOL, WLEFT, WRIGHT -display bug fixes (SPLIT) -FIND/PREV/NEXT will now abort a REPEAT if string not found. V1.11 RELEASE NOTES -Bug fixes (mainly graphical mistakes). -User keymappings are disabled in command mode (so you can unmap single ascii characters you may have mapped). -Illegal key combinations no longer give garbage (e.g. ALT-CURSOR-DOWN) you can, of course, still map them to anything you wish. -Save now checks for error conditions on write. -Uses Default Console Keymap (i.e. no longer assumes USA)... but there *is* some stangeness. V1.00 RELEASE NOTES -has find, but no replace function -assumes USA keyboard (fixed 1.11) -disk files written out use spaces instead of tabs&spaces VII COMPILING DME compiles only under AZTEC. You must compile with the 32 bit int option, but may use the small code/data model. A support lib which I have created (SUP32.LIB) is also required. I use a precompiled symbol file containing ALL the AMIGA includes (but not any Aztec standard includes).
