* - added resize-window command to change a window's size to the
* specified argument
* - improved help's logic not to re-read the file if it was already
* in a buffer
* - added MAGIC mode to all structures and command tables, but the
* regular expression code that John Gamble is writing is not ready.
* 18-may-86
* - added interactive prompt requests in command line execution (i.e.
* while executing a macro, a parameter starting with an at sign (@)
* causes emacs to prompt with the rest of the parameter and return
* the resulting input as the value of the parameter).
* - added arguments to split-current-window to force the cursor into
* the upper or lower window.
* 20-may-86
* - added support for the Microsoft C compiler as per the changes
* sent in by Oliver Sharp
* - made some upgrades and fixes for VMS sent in by Guy Streeter

* buffer will still have a problem >65535 that can not be solved
* until I restructure it.
* - grouped paragraph commands and word count together under symbol
* WORDPRO to allow them to be conditionally made (or not)
* 13-jun-86
* - re-wrote kill buffer routines again. Now they support an unlimited
* size kill buffer, and are (in theory) faster.
* - changed delete-next-word (M-D) to not eat the newline after a word,
* instead it checks and eats a newline at the cursor.
* 17-jun-86

* window from the top/bottom
* - added support for the Data General 10 MSDOS machine
* - added save-window (unbound) and restore-window (unbound) commands

* of a buffer
* - added argument to update to selectively force a complete update
* - added update-screen (unbound) command so macros can force a

* repeat counts could also be prompted and fetched from buffers
* [this broke later with the exec re-write....]
* - added write-message (unbound) command to write out a message
* on the message line (for macros)
* - changed ifdef's so that color modes are recognized as legal in
* b/w version, and simply do nothing (allowing us to use the same
* script files)
* [Released version 3.7 on July 1 to the net and elswhere]
* 2-jul-86
* - Changed search string terminator to always be the meta character
* even if it is rebound.
* 3-jul-86

* including control and spec characters
* 22-jul-86
* - fixed replaces() so that it will return FALSE properly on the

* - replace AZTEC/MSDOS agetc() with a1getc() which won't strip
* the high order bit
* 30-mar-87
* - changed list-buffers (^X^B) so that with any argument, it will
* also list the normally invisable buffers
* - added store-procedure and execute-procedure/run (M-^E)
* commands to store and execute named procedures.
* 31-mar-87
* - Fixed infinite loop in ^X-X command (when [LIST] is the
* only buffer left) as pointed out by John Maline
* - made filenames in getfile() always lower case as pointed
* out by John Maline
* 2-apr-87
* - Fixed buffer variables so they would work on non-current displayed
* buffers. They should now work with ALL buffers....
* 3-apr-87
* - Yanked AZTEC profiling code....not very useful
* - Modified IBMPC driver so it will not start in EGA mode
* - allow the next-buffer (^X-X) command to have a preceding
* non-negative argument.
* 14-apr-87
* - added John Gamble's modified search.c. The code has cut apx
* 200-300 bytes off the executable.
* - added the &RND function to generate a random integer between
* 1 and its arguments value. Also $SEED is availible as the
* random number seed.
* - changed the -k command line switch so if there is no argument,
* it will prompt for one when the file is read
* 15-apr-87
* - added 20 bytes of buffer in getval()'s local argument alloc so
* when it returns a value, it has enough stack space to do at least
* one strcpy() before stomping on the returned value. ALWAYS call
* getval() ONLY from within a strcpy() call.
* - made $curcol return a 1 based value instead of a zero based one.
* [changed this back later for 3.8o it was simply wrong.....]
* 16-apr-87
* - re-wrote bytecopy() for AZTEC & MSDOS so it null terminates the
* string.
* - changed pipe() to pipecmd() to avoid conflicts with various
* UNIX systems
* 24-apr-87
* - changed open parameters on AMIGA window open to 0/0/640/200
* [Froze and released v3.8i via BBS net]
* 14-may-87
* - added nop (M-FNC) that gets called on every command loop
* - added $wline, returns and sets # lines in current window
* - added $cwline, returns and set current line within window
* - added $target, returns/sets target for line moves
* - added $search, returns/sets default search string
* - added $replace, returns/sets default replace string
* - added $match, returns last matched string in magic search
* 29-may-87
* - rewrote word deletes to not kill trailing non-whitespace after
* the last word. Also a zero argument will cause it to just delete
* the word and nothing else.
* - more fixes for the search pattern environment variables
* 30-may-87
* - forced all windows to redraw on a width change
* 2-jun-87
* - forced clear-message-line to overide $discmd
* - added mlforce() routine and call it in clear-message-line,
* write-message and when $debug is TRUE
* - recoded the startup sequence in main()....Much Better...
* 4-jun-87
* - forced interactive arguments ( @"question" ) to ALWAYS be echoed
* regardless of the setting of $discmd.
* 7-jun-87
* - started adding support for Turbo C under MSDOS
* 11-jun-87
* - words now include ONLY upper/lower case alphas and digits
* - fixed some more bugs with the startup..(ORed in the global modes)
* - took more limits off the self-insert list....
* 16-jun-87
* - macro debugging now displays the name of the current macro.
* - fixed a problem in expandp() in search.c that kept high-byte
* characters from working in search strings
* 18-jun-87
* - added &sindex <str1> <str2> function which searches for string 2
* within string 1
* [released verion 3.8o internally]
* 19-jun-87
* - added $cmode and $gmode to return and set the mode of the
* current buffer and the global mode
* - separated findvar() out from setvar() so it could be used in
* the !LOOP directive (which got canned....read on)
* - %No such variable message now types the name of the offending
* variable
* 22-jun-87
* - fixed startup bug when editing the startup file
* - added the !LOOP <var> <label> directive
* 26-jun-87
* - dumped !LOOP......added !WHILE. This needed and caused a vaste
* reorginization in exec.c which mainly involved moving all the
* directive handling from docmd() to dobuf(), in the process
* getting rid of a lot of junk and making the result smaller
* than it started.....(yea!)
* - added $tpause to control the fence flashing time in CMODE.
* The value is machine dependant, but you can multiply the
* original in macros to stay machine independant. (as
* suggested by Baron O.A. Grey)
* - added hook to execute M-FNR (null) during a file read, after
* the name is set and right before the file is read. Took out
* any auto-CMODE code, as this is now handled with a macro.
* (also suggested by Baron O.A. Grey)
* - Added Baron O.A. Grey's SYSTEM V typeahead() code...I hope
* this works....if you check this out, drop me a line.
* - Added new variable $pending, returns a logical telling if
* a typed ahead character is pending.
* 29-jun-87
* - Made adjustmode() use curbp-> instead of curwp->w_bufp-> which
* fixed some bugs in the startup routines.
* - added $lwidth to return the length of the current line
* 2-jul-87
* - Added &env <str> which returns the value of the environment
* variable <str> where possible
* - Fixed a NASTY bug in execbuf()..the buffer for the name
* of the buffer to execute was NBUFN long, and got overflowed
* with a long interactive argument.
* 3-jul-87
* - Moved the loop to match a key against its binding out of execute()
* to getbind() so it could be used later elsewhere.
* - Added &bind <keyname> which returns the function bound to the
* named key
* - changed execute-file to look in the executable path first...
* 6-jul-87
* - changed $curchar to return a newline at the end of a line and
* it no longer advances the cursor
* - a lot of minor changes sent by various people....
* 7-jul-87
* - some amiga specific fixes as suggested by Kenn Barry
* - added $line [read/write] that contains the current line in the
* current buffer
* - changed $curcol so setting it beyond the end of the line will
* move the cursor to the end of the line and then fail.
* 10-jul-87
* - added a number of fixes and optimizations along with the rest
* of the TURBO-C support as submited by John Maline
* 13-jun-87
* - caused dobuf() to copy lastflag to thisflag so the first
* command executed will inherit the lastflag from the command
* before the execute-buffer command. (needed this for smooth
* scrolling to work)
* - made flook() look first in the $HOME directory, then in the
* current directory, then down the $PATH, and then in the
* list in epath.h
* 14-jul-87
* - added some fixes for VMS along with support for the SMG
* screen package as submited by Curtis Smith
* 15-jul-87
* - fixed M-^H (delete-previous-word) so it can delete the first
* word in a file....I think there may be more of this kind of thing
* to fix.
* 16-jul-87
* - added code to allow arbitrary sized lines to be read from files..
* speed up file reading in the process.
* - made out of memory conditions safer.. especial on file reads
* - fixed a bug in bind having to do with uppercasing function
* key names (submitted by Jari Salminen)
* - made ST520 exit in the same resolution that EMACS was started in
* (for the 1040ST)
* [FROZE development and released version 3.9 to USENET]
* {It never made it.....got killed by comp.unix.sources}
* 15-sep-87
* - added support for Mark Williams C on the Atari ST
* - made the MALLOC debugging package only conditional on RAMSIZE
* - added code for flagging truncated buffers
* 23-sep-87
* - fixed &RIGHT to return the <arg2> rightmost characters
* - fixed a buffer in getval() to be static....things are stabler
* now.
* - moved all the stack size declarations to after include "estruct.h"
* they work a lot better now....... (rather than not at all)
* - made Atari ST spawns all work with MWshell
* - fixed spawning on the 1040ST under MWC
* 27-sep-87
* - added &exist function to check to see if a named file exist
* - added &find function to find a file along the PATH
* - added -A switch to run "error.cmd" from command line
* - added $gflags to control startup behavior....
* 03-oct-87
* - changed ":c\" to "c:" in epath.h for the AMIGA as suggested
* by Tom Edds
* - added binary and, or, and xor functions as submited by John Maline
* (&band &bor and &bxor)
* - added binary not (&bnot) function
* - added fixes for gotoline() and nextarg() as submited by David
* Dermott
* - fixed return value of $curwidth as submitted by David Dermott
* - fixed several calls to ldelete() to have a long first argument
* (pointed out by David Dermott)
* - Fixed a bug in stock() which prevented uppercase FN bindings as
* pointed out by many people
* - changed dofile() to make sure all executed files don't conflict
* with existing buffer names. Took out cludged code in main.c to
* handle this problem... this solution is better (suggested by
* Don Nash)
* 05-oct-87
* - added in John Gamble's code to allow for a replacement regular
* expresion character in MAGIC mode
* [note: under MSDOS we are still TOO BIG!!!!]
* - added overwrite-string as a new user callable function, and
* lowrite(c) as an internal function for overwriting characters
* - added &xlate function to translate strings according to a
* translation table
* 10-oct-87
* - added code to allow emacs to clean its own buffers on exit.
* useful if emacs is used as a subprogram. Conditional on
* the CLEAN definition in estruct.h
* 14-oct-87
* - swallowed very hard and switched to LARGE code/LARGE data model
* - packaged and released version 3.9c internally
* (MSDOS executables compiled with TURBO C Large model)
* 16-oct-87
* - temporary fix for FUNCTION keys now includes the Meta-O sequence
* if VT100 is definined (submited by Jeff Lomicka)
* - an VT100 also triggers input.c to force ESC to always
* be interpeted as META as well as the currently bound key
* - fixed a bug in the VMSVT driver as pointed out by Dave Dermott
* - added a size parameter to token() to eliminate problems with
* long variable names. (as sugested by Ray Wallace)
* 18-oct-87
* - fixed a bug in the free ram code that did not clear the buffer
* flag causing emacs to ask for more confirnmations on the way out.
* 19-oct-87
* - added ^X-$ execute-program call to directly execute a program
* without going through a shell... not all environments have this
* code completed yet (uses shell-command where not)
* [Froze for 3.9d release internally]
* 28-oct-87
* - added code for Atari ST DENSE mode and new bell as submited
* by J. C. Benoist
* - made extra CR for ST files conditional on ADDCR. This is only
* needed to make the desktop happy...and is painful for porting
* files (with 2 CR's) elsewhere (Also from J. C. Benoist)
* - added optional more intellegent (and larger) close brace
* insertion code (also from J. C. Benoist)
* 4-nov-87
* - fixed AZTEC spawning... all MSDOS spawns should work now
* - a META key while debugging will turn $debug to false
* and continue execution.
* [Froze for version 3.9e USENET release]
* 13-dec-87
* - added a change to the system V termio.c code to solve a keyboard
* polling problem, as submited by Karl Lehenbauer
* - removed a "static" from the mod95() function declaration
* in crypt.c to make MSC happy (by Malcolm MacNiven)
* - added code so the new exec routines in spawn.c are working
* under MSC (By Malcolm MacNiven)
* - fixed the mixed space/tab entabbing bug as suggested
* by Michal Jaegermann
* - added the missing brace in the VT100 code in getcmd()
* (This one was submited by many different people)
* - added more intelligent spawning for TURBO C as submitted
* by Bob Montante
* - added support for the WICAT computers running under the WMCS
* operating system as submitted by Bruce Hunsaker
* 16-dec-87
* - re-wrote fillpara(). Its 4 times Faster!!!
* - moved M-FNR binding to $readfile ie to make emacs execute
* a macro when reading files:
* set $readhook "nop" ;or whetever
* 19-dec-87
* - new search algorithm from Geoff Gibbs, cleaned up by John Gamble.
* its over 30 TIMES FASTER!!!! using a simplified Boyer and Moore
* pattern search. This effects all the but MAGIC search commands.
* 22-dec-87
* - narrow-to-region (^X-<) and widen-from-region (^X->) allow you
* to make all but a region invisable, thus all global commands
* can act on a single region.
* - a numeric argument on the select-buffer (^X-b) command makes
* that buffer become "invisable"
* - M-FNC becomes $cmdhook
* M-FNW becomes $wraphook
* 23-dec-87
* - made unmark-buffer (M-~) update the mode lines of all windows
* pointing into the unmarked buffer
* 28-dec-87
* - added new prefix MOUS (coded as MS-) for dealing with mice
* 29-dec-87
* - vastly reorginized machine dependant code. Put termio.c and
* spawn.c together and then pulled out msdos.c, unix.c, wmcs.c,
* atari.c, amigados.c, and vms.c. These are the operating specific
* source files now.
* 30-dec-87
* - cleaned up msdos.c. Got rid of two unused spawn functions for
* LATTICE. Also removed attempt to lookup SHELL variable to
* find the command processer. This is definatly not applicable
* here as COMSPEC should always be the name of the reloaded
* command processor.
* 20-jan-87
* - added Jeff Lomicka's ST mouse support and added some
* appropriate code to input.c to support this.
* - added buffer name completion to the select-buffer (^X-B)
* command as submitted by Martin Neitzel.
* - changed some function names:
* abs => absv
* atoi => asc_int
* ltoi => long_int
* setmode => setmod
* strncpy => bytecopy
* 25-jan-88 By Jeff Lomicka
* - Added parsing of keypad keys, LK201 function key sequences, mouse
* sequences (VaxStation form and BBN BitGraph form), and the cursor
* position report to VMSVT.C. This will require a change in the way
* that VMS users bind functions to their function keys or keypad
* keys. This also defines a defacto-standard for the names of the
* numeric keypad keys, based on the VT100 and compatible terminals.
* - Added MOUSE.C to DESCRIP.MMS, and changed it to reference ME.OPT,
* and to generate ME.EXE.
* - Renamed MICROEMACS.OPT to ME.OPT so that the filename would fit
* on smaller systems.
* - Added capability for copy and paste from the terminal-wide
* copy/paste buffer. This allows copy and paste of the select region
* from and to non-cooperating sessions in other windows. (The
* addition of the MOUSE handling routines disables the transparent
* use of the VWS copy/paste mechanism.) There may be a bug in the
* PASTE section of this code. On some VWS systems, you may get a
* bunch of Hex characters instead of text. I'm looking in to finding
* out what is really supported in the released versions of VWS. This
* code is conditional based on MOUSE & VMSVT. Code was added to
* VMSVT.C. Added bindings for to ebind.h. Yank is on ^X^Y. Copy is
* on ^XC. If MOUSE & VMSVT is true, this binding overides the use of
* ^XC for spanwcli. [This won't stay.. alternative binding?]
* Also added definitions for this to efunc.h.
* - Added #define of CPM to estruct.h. It is used in FILE.C. You
* might want to delete it again. [It was deleted..no CPM support]
* - Added noshare attributes to all data in many modules.
* - Re-introudced XONDATA condition that was in 3.9eJ's TERMIO.C into
* VMS.C. (This was overlooked by Dan in making 3.9g.)
* - Appended a ":" to the "MICROEMACS$LIB:" path element in the VMS
* portion of EPATH.H.
* - Fixed mouse reports from VMSVT.C to correspond to the code in 3.9g.
* - In INPUT.C, added VMS to list of systems that generate FN key and
* mouse reports with leading 0 bytes.
* - In order to accomodate callable editor support, I had to arrange
* so that some of the CALLED features are active all of the time,
* particularly EXIT HANDLING. I changed all calls to exit() into
* calls to meexit(). There is a great need to divide up exits
* between error exits that aren't expected to return, and exits that
* just set the exit flag. Places that didn't expect exit to return
* should be changed to return immediately after calling exit, so that
* the command loop can catch it and return. This error handling
* business is a real mess right now.
* - Re-arranged main() so that most of the guts are in called
* routines, so that there can be more than one entry point into the
* program. Note, now, the possiblity of adding recursive-edit as a
* function that you can call from a macro.
* - Added the universal symbol ME$EDIT to the VMS version as a second
* entry point, for use when called by MAIL and NOTES, which use
* LIB$FIND_IMAGE_SYMBOL and perform run-time linking with their text
* editor. This stuff works great!
* - Changed Atari-ST makefile to link without -VGEM, so that you will
* get argc and argv.
* - Fixed ST520.C so that screen would be redrawn when we notice that
* desk accessories exit, and so that the mouse will be turned off
* when exiting into a shell (If text cursor was on, mouse is left
* off).
* - Changed ST520.C to have bindings for keypad keys, with PF1 "("
* key as metac, so that it can be used as GOLD prefix. Uses GOLDKEY
* option in ESTRUCT.H.
* 26-jan-88 Daniel Lawrence...
* - cleaned up coding in main.c
* - changed more function names
* itoa => int_asc
* ltoa => long_asc
* 27-jan-88
* - added terminal initilizer string output to tcap.c as submitted
* by Ge' Wiejers
* - switched the -A command line switch to be -E the way MWC demands
* that it be. Also had to move -E to -C (for Change...)
* 02-feb-88
* - changed META and ^X prefixes to use a new mechinism. Hitting
* a prefix stores it as a pending prefix.
* 05-feb-88
* - changed emacs to use ^M for line terminators instead of
* ^J. This required LOTS of changes. Now, however, we can
* search for and manipulate ^M.
* - fixed getcmd() to work again so that describe-key and
* interactive binding functions work again.
* - added $sterm environmental variable. This hold the current
* value of the keystroke needed to terminate search string
* requests. The value in here is also automatically reset
* any time the meta-prefix is rebound, the the meta-prefix's value
* 06-feb-88
* - fixed bug in stock().. real control characters in command lines
* now bind properly
* [BBS release of version 3.9i]
* 23-feb-88
* - added buffer name completion to delete-buffer (^XK) and reorginized
* code their to gain back 1 K
* - added $modeflag to allow us to hide the modelines.
* - added $sscroll to allow smooth scrolling... (I don't like this
* but there were too many requests for it).
* - added $lastmesg to hold last message EMACS wrote out
* 04-mar-88
* - added Alan Phillip's mods to support the VGA adapter on the
* IBM PS/2 machines. Modified it a little.
* 15-mar-88
* - Forever twiddling with the startup code, I moved the initialization
* of exitflag to main() to allow a startup file to exit EMACS
* properly. Also had to make meexit always return(TRUE) regardless
* of the exitstatus. (Ie it always works and doesn't abort the macro)
* 17-mar-88
* - added code to change hard tab size with $tabsize variable
* - added binary search to fncmatch()
* 28-mar-88
* - optimized the IBMPC version in TURBO C by supplying mixed memory
* mode information (NEAR and PASCAL). The executable is down to
* 89K..but remember to name the code segment (from the options menu)
* 1-apr-88
* - added remove-mark (^X<space>) to allow you to unset the mark
* in the current window.
* 8-apr-88
* - Lots of twiddling with the mixed memory model TURBOC IBM-PC
* version... its 87K long now and fairly stable
* - changed behavior of CMODE when inserting blank lines
* - tightened stack usage from 32K to 20K
* 9-apr-88
* - added new cinsert(). blank lines no longer confuse the CMODE
* indentation. Trailing white space is deleted when newline is
* hit in CMODE.
* 12-apr-88
* - fixed long standing bug in query-replace-string. When the line the
* point originally starts on is extended (thus re-malloced) a '.',
* aborting the replace and returning to the original replace had
* locked things up. no more.
* 07-may-88
* - fixed bug in narrow() ... it works everywhere now.
* [BBS release of 3.9n]
* 3-june-88
* - removed restriction against deleting invisable buffers
* - a lot of little fixes suggested by Dave Tweten
* 10-jun-88
* - added "safe save"ing as coded by Suresh Konda.
* (when writing a file to disk, it writes it to a temporary file,
* deletes the original and renames the temp file)
* - added $ssave flag to enable or disable safe file saving
* 12-jun-88
* - added automatic horizontal window scrolling. $hscroll (default
* is TRUE) controls if it is enabled. $fcol is the current first
* column of window in screen column one. $hjump determines the
* number of columns scrolled at a time.
* - changed version number to 3.9o
* 22-jun-88
* - made binary searches start from 0 instead of one... EMACS can
* find the first of many lists again.
* - more debugging things. Added the dump-variable command which
* creates a buffer (like list-buffers does) with all the environment
* and user variables and their values. Also the display (^XG)
* command prompts and lists the value of a variable. These are
* both conditional on the DEBUGM symbol in estruct.h
* 1-jul-88
* - fixed a bug in showcpos() which did not report the proper value
* for the current character when issued at the end of the file
* [Released internally as 3.9p]
* 3-aug-88
* - changed keyname in stock() in bind.c to unsigned char for
* compilers that don't default. This allows more arbitrary
* rebinding. (submitor: David Sears)
* 12-aug-88
* - changed wrap-word to force $fcol to 0
* - changed fill-paragraph (M-Q) to force $fcol to 0
* - added -i command line switch to initialize a variable's value
* for example: emacs -i$sres VGA
* 26-aug-88
* - changed code in updateline() in display.c to remove reliance
* on well behaved pointer subtraction (submitted by Kenneth Sloan)
* - fixed potential bug in fileio.c in ffgetline()
* (submitted by John Owens)
* 6-sep-88
* - &right and &mid now check their arguments so the bytecopy can not
* start past the end of the string.
* - added $writehook to execute macroes when writing files
* - added $exbhook to execute macro when exiting an old buffer
* - added $bufhook to execute macro when entering a new buffer
* 14-sep-88
* - asc_int() now ignores trailing non-digits
* 15-sep-88
* - added &trim function to trim whitespace off a variable
* - changed message "Out of memory while inserting string" to
* "Can not insert string" as this error can result when the
* current buffer is in VIEW mode as well.
* - made trim-line, entab-line, and detab-line work on the
* current region if they have no arguments. Also added alias
* trim-region, entab-region and detab-region. The old names
* will hang about for a version, then dissapear. I like the
* new functionality much better.
* 25-sep-88
* - Inserted the macros isletter(), isuppper(), islower(), and
* CHCASE() whereever appropriate, replacing explicit character
* comparisons. When DIACRIT is set to one, they become functions
* and know about the extended ascii character set. Functions right
* now are in for MSDOS.C - other machines to follow. From J. Gamble.
* 26-sep-88
* - moved all text constants out to a language specific header file
* and left an english version of the constant in a remark at its
* occurence.
* - added $language to return the language of the current version
* - added elang.h to call the proper language specific module
* 2-oct-88
* - removed DIACRIT conditional. Its there all the time now. Ripped
* the old code, and replaced it with a upcase[] and lowcase[]
* table. Functions to manipulate it are now in new source file
* char.c and can be made conditional on system and language.
* Added table for extended MSDOS modeled after John Gamble's
* code.
* 5-oct-88
* - got rid of CHCASE()..[except in the MAGIC mode search code]
* I ALWAYS force to upper or lower, and never simply swap. They
* are now uppercase() and lowercase() in the new char.c source file.
* 7-oct-88
* - added all the needed code to use TERMCAP on UNIX to interpret
* function and cursor keys. A rather slimy trick involving
* the key timing is used, and this makes keyboard macroes
* a little dicy....
* - added the DIACRIT compilation flag back for people who
* want more speed in MAGIC mode.
* 10-oct-88
* - as suggested by Michael Andrews, when the current buffer is
* in view mode, don't preallocate expansion room in new lines.
* (ie we aren't editing them anyway!)
* - added Microsoft Mouse drive... went very well. It all appears
* to work, just like the Atari ST mouse driver.
* 11-oct-88
* - recieved and tested german.h header file from Martin Neitzel
* (unido!sigserv!neitzel@uunet.uu.net)
* 15-oct-88
* - recieved and tested dutch.h header file from Paul De Bra
* (debra@research.att.com)
* - fixed a lot of mouse movement problems. Dragging a mode line
* sideways horizontally scrolls a it's window. Fixed positioning
* problems with scrolled and extended lines.
* - added $msflag to turn the mouse off
* - added $diagflag. When set to FALSE, no diagonal movement is
* possible. Vertical movement has precidence, but an explicit
* horizontal drag still works.
* - grabbing and dragging the last char of the command line allows
* you to resize the editing screen. This should be tied into
* various windowing systems later.
* - write mouse-region-(down/up). See the emacs reference docs on the
* exact behavior of these.
* - deleted the old mouse-(kill/yank)-(up/down). They are
* redundant now, and don't work as well as mouse-region-*.
* 2-nov-88 [changes submitted by Allen Pratt from ATARI]
* - created DIRSEPSTR and DIRSEPCHAR definitions for directory seperators
* - added TTflush in bindtokey() to force space out to terminal after
* binding name.
* - fixed a pointer casting problem in display.c involving pointer subtraction
* - removed the cursormove() from the beginning of mlwrite() so
* the cursor need not jump to the command line if the fisplay
* is disabled by setting $discmd to FALSE.
* - added >c to get a emacs command sequence and return it as
* a bindable string
* - changed scrnextup -> nextup, scrnextdn -> nextdown, and
* mlreplyt -> mltreply to make short symbol compilers happy.
* - added "print" as a synonim to "write-message".
* - added "source" as a synonim to "execute-file".
* - added a M-^X binding to the execute-command-line command
* 4-nov-88
* - changed $tabsize to $hardtab. Added $softab as the current
* softtab size (previously only changable by the ^I (handle-tab)
* command.
* - fixed various problems in reglines() and made ^X^D (detab-region)
* and ^X^E (entab-region) use the current hard tab setting.
* - execute-command-line (M-^X) when executed within a macro line
* (which sounds redundent) will force all of the arguments of
* the executed command to be taken interactivly. I needed this
* for the new macro to allow mouse functionality on the
* function key window.
* - taking Michael Andrew's suggestion to its conclusion, we no longer
* allocate any extra space except when inserting. This has
* substantially decreased the memory usage. Note that when
* we must explicitly set l_used to the proper amount since lalloc()
* is not responcible for the rounding up.
* - arranged to allow getstring() to return a NULL result. Aborting
* out of an interactive prompt now will properly terminate a macro.
* [Released the 3.10 BETA test version...yes the ATARI version is broke]
* 24-nov-88
* - fixed system V input char HOG problems as submitted by
* Kjartan R. Gudmundsson. Also eliminated some other 7 bit filters
* in unix.c at the same time.
* - reading function keys into table has been fixed in TCAP.C. It will
* no longer attempt to strcpy NULL pointers.
* 1-dec-88
* - multiple marks are now implemented. (What a task...). Set-mark
* (M-<space>), remove-mark (^X<space>) and exchange-point-and-mark
* (^X^X) all take a numeric argument from 0 to NMARKS-1 (9 now).
* 2-dec-88
* - added goto-mark (M-^G) which moves the point to the requested mark.
* - fixed some VMS things that Curtis pointed out...
* - fixed bug in crypt() algorith!!!! This works properly now. I had
* to add a $oldcrypt environment variable to trigger the broken
* behavior so people could decrypt their old files. I will probably
* have to live with this.....
* 15-dec-88
* - added end-of-word command to advance just past the end of a word.
* 20-dec-88
* - added definitions for SUN's OS and SCO XENIX to allow us to use
* specific calls in those OSs for waiting and timing.
* - merged in XTCAP.C as submitted by Guy Turcotte into tcap.c. This
* mirrors the BSD 4.3 changes for function keys for the SCO XENIX
* and SUN OS versions
* 14-jan-89
* - added $region as a read only variable (max 128 chars) of the
* current region (as suggested by Allan Pratt)
* - changed KEYTAB structure to allow us to bind user macroes
* (buffers) to keys as well as C functions. Lots of changes
* for this.
* 18-jan-89
* - finished changes for the new KEYTAB structure.
* - modified describe-bindings to display the bound macroes.
* - added arguments to nullproc() in main.c (BUG FIX!)
* - tried (and succeeded) in defining the pascal keyword
* for MSDOS & TURBO. A 2k reduction in the executable was nice.
* - added macro-to-key (^X^K) function to bind a macro to a key.
* 19-jan-89
* - made numeric arguments to keys bound to macroes repeat those
* macroes n times.
* - modified docmd() to look for a macro name if it could not find
* a function name. Again a numeric leadin implies repitition.
* - added machine code execpr() function to the IBMPC version
* because under NOVELL Netware, the DOS 4B exec call does not
* preserve the stack on exit... thus execprog() would die. This
* requires that you add execpr.obj to the make and link files!
* There is a symbol (NOVELL) in estruct.h to control this code
* being included.
* 24-jan-89
* - various bug fixes and type fixes as suggested by the high C
* compiler on the IBM-RT
* 1-feb-89
* - changed the fgetc() in unix.c to a read() under V7 and BSD so
* the time dependant function key checking works.
* - added a support for Hewlet Packard's UNIX system which
* is a System V with BSD 4.3 enhancements. This is controled
* by the HPUX symbol in estruct.h.
* 5-feb-89
* - modified mouse-region-up so right clicking down on a modeline and
* then releasing closes that window
* 12-feb-89
* - Goaded onward by file completion code submitted by Fuyau Lin, all
* the completion code has been re-written and layered properly.
* Any OS specific driver need to now supply getffile() and
* getnfile() to supply a completion file list, or these can
* return NULL on systems where this is not possible. All this code
* is conditional on the COMPLET symbol in estruct.h.
* 17-mar-89
* - system V code from April 1989 "C Users Journal" installed in
* UNIX.C. Hope this puts that problem to rest.
* - Jeff Lomicka fixed a lot of mousing bugs in ST520.c
* - Re-wrote AMIGADOS.C. This should work properly with INTUITION
* and lots of windowing (resizing, mousing, etc.)
* - more additions for the DATA GENERAL from Doug Rady. (read
* the history in aosvs.c for details).
* - orginized the NOSHARE, VIOD and CONST keywords better.
* - A lot of general cleanup.
* [Released as version 3.10 to the world]
