I might be wrong, but I think that program predates Windows and was widely used in pure DOS days. I remember using it to edit config.sys and autoexec.bat to tweak settings to run DOS games, before Windows days. (It could be because having Win 3.1 installed on a machine brings the program along in DOS though)
The amazing thing about it was that even in pure DOS, with no Win 3.1 running, it lets you use your mouse too in the editor (provided that you have drivers set up right in config.sys etc.), I guess in a similar way as how DOS games use the mouse.
It isn't exactly the same, but mcedit tends to be very dos editor-like (and as a sidenote, i always find it weird that Linux/Unix console programs look so primitive compared to similar programs for DOS).
Thanks I'll check it out, when I get back to my Linux machine. I agree with you that linux file editors look very primitive compared to what was available on DOS.
