So, like I said before, I have Tufting machines controlled by PC's. Software running on DOS.

My question is, these EXE's do some things that I need to change, they check the A drive for instance when the C should be checked...

Can an EXE file be decompiled in some way... I think the code is written in Turbo Pascal or QBasic

Assuming that the SUBST command doesn't do the trick you can use a decompiler. They can be a PITA in that trying to decompile a Pascal program using a decompiler intended for C will give you goofy looking results.

But all that you are really interested in is finding where the "A" gets loaded into the AX reg and to change it in the binary to a "C".

The idea is to use breakpoints to stop the program close to where the drive letter gets loaded and find that location in your binary (.exe). Then using a hex editor you would change that byte in the program to the one that you want.


Here are some links on disassemblers.
