I have a need to enlarge the stack for an existing .EXE file.  I understand
that if I had any MS language, I would have EXEMOD.EXE, which does this
sort of thing.  Unfortunately, I don't and I don't.

The need arises because I have a *lot* of SET commands in AUTOEXEC.BAT,
setting up the environment for various tools that I use, and this silly
program loads the whole environment into the stack rather than extracting
what it needs.  Thus, I need to give it a bigger stack.

I have the feeling that this is pretty easy to do, and I'm comfortable
writing a program (in Turbo C) or doing binary patches by hand.  I just
don't know what to modify.  I can't quite convince myself that I understand
all the fields in the EXE header.

Could someone who understands these things enlighten me?
