yep, not being sarcastic or nething, but it's called debug.exe /
debug.com, i can't remember exactly the extension, but it comes with
MSDOS, and if you haven't got MSDOS, then i'm sure it won't make them
bankrupt if you took a little copy of the proggie off of a friend or
somin' :)

debug.exe, unfortunatly is the best to dissasemble, and there isn't
really anything better.

the only problem with .asm is that is is 100% compiled, line labels
are lost etc. so there is no GOOD way of decompiling back into the
source code other than using debug.

sorry if you already knew all that, but i am only a novice at .asm who
would like to help other novices.

hope that answered your question... IitM :)
