- I have succeeded in installing demacs on an 80386 MSDOS system and it works.
- Formerly, I was using freemacs and was reasonably happy with it until
- I started losing a lot of work when it hung the system, presumably from
- insufficient memory. That is what persuaded to finally get around to
- installing demacs which had been lying around uninstalled on the machine.
-
- Now that I am using demacs, I am noticing a lot of ways in which it is
- superior to and inferior to freemacs. So I am wondering what I can do to
- give demacs the good features I got used to with freemacs.
-
- For example:
-
- (1) When I suspend freemacs with ^X^Z and run the computer algebra package
- REDUCE, either I can do so or I get an error message saying there is not
- enough memory. But in either case, when I type exit, I can return to
- freemacs. But when I tried this with demacs, typing ^Z to suspend, I
- was able to run REDUCE but was unable to return to demacs by typing exit.
-
- (2) When I ran demacs on the file I had left behind, I got a message about
- how I should consider M-x recover-file. But when I ran it, instead of
- giving me the subsequent prompts, it simply hung the machine. Since
- since the filename and extension seem to matter, I should mention that
- the file was named prox.tex. I've never tried M-x recover-file with
- freemacs.
-
- (3) In freemacs, you can use the alt key nearly interchangeably with the
- escape key. In demacs apparently you cannot.
- (4) In freemacs, you can use both the backspace and the delete keys for
- deletions, whereas in demacs the backspace key triggers HELP.
- (5) In freemacs, if I give the command M-x search-forward and then want
- to search for the same string it remembers the string so that you don't
- have to type it again. If you issue the same M-x command twice in a row,
- you don't have to type it the second time because it remembers it.
- (6) ^@ works in freemacs to mark the beginning of something you want to
- move into the yank buffer, this being ended by ^w.. When I type ^@
- in demacs, I get a beep but no message about the mark being set. By
- ^@ I mean ^-shift-2.
-
- I will prefer to work with demacs because it is more powerful, implements
- more of GNU emacs, including the info facility, but I would like it better
- if I could equip it with the features I have noted in freemacs and if I
- could get some of the features it is supposed to have to work, such
- as M-x recover-file and ^@ and allowing other processes such as REDUCE
- to run while it is suspensed.
