- XEmacs does not yet work under MSDOS. If you would be interested in
- porting XEmacs to MSDOS, please contact Chuck Thompson <cthomp@cs.uiuc.edu>.
-
- The following information applies to FSF Emacs, not to XEmacs.
-
- ---------------------------------------------------------------------------
- This file describes use of Emacs 19 on MS-DOG.
-
- * The commands `mode25' and `mode4350' change the number of
- lines of the screen. You get 43 lines on an EGA monitor, 50 on
- a VGA monitor.
-
- * Ctrl-Break takes the place of C-g. Using compilers prior to
- djgpp 1.11 maint 5, you should not use Ctrl-Break unless you
- run under DPMI (i.e., you are using Windows, Qdpmi, ...)
-
- Actually, if Emacs is in an endless loop, you might as well go
- ahead and try. Usually it works, but sometimes Emacs crashes
- with a stack trace. This is not an Emacs bug.
-
- * Character codes 0200-0237 are self-inserting.
-
- * The keyboard support is made as X-like as possible. This means
- that events like M-S-f1 will be generated (by Shift + Alt + f1).
-
- * Mouse support is partially implemented.
-
- * The `compile' command works on MS-DOG, but it waits for the
- compilation to finish before letting you edit again. There's no other
- way to do it, given the lack of asynchronous processes.
-
- * The function `expand-file-name' maps upper case letters to lower
- case letters, since MS-DOG does not distinguish.
-
- * The new buffer-local variable `buffer-file-type' controls whether a
- file contains text (newlines will be written as CR+LF) or binary data
- (newlines written as LF). Text is specified by nil, and binary by t.
- The status of a buffer can be seen in the mode line as "T:" or "B:"
- before the major mode.
-
- Normally `buffer-file-type' is set automatically from the variable
- `file-name-buffer-file-type-alist' which is an alist mapping regexps
- to file types.
-
- You can visit a file explicitly as text, or as binary, using the
- commands `find-file-binary' and `find-file-text'.
-
- * New variables `binary-process-input' and `binary-process-output'
- control whether temporary files are opened as binary or as text
- files. nil means text, and t means binary. The difference is
- translation of CR+LF to LF and C-z handling.
-
- * Environment variables "HOME", "EMACSPATH", "TERM", "SHELL",
- "USER", "NAME", and "TZ" are given default values as suitable
- for a single user system. See src/msdos.c for details.
-
- * The function `substitute-in-file-name' disregards case in
- environment variables, as the MS-DOG SET command does.
-
- * The variable `msdos-shells' contains a list of commands that
- are shells. This variable is used to convert to map Unix-like
- commands like "$SHELL -c /some/command" to MS-DOG commands
- like "$SHELL /c \some\command".
