C Language Source Code for Converting BAT to COM - China DOS Union Forum

Recently I discovered a C language original code that converts BAT files to COM. After compilation, the effect is good. The converted COM file is much smaller than the one converted by BAT2COM, and the execution efficiency is also faster. To respect the original author's copyright, the source program is not listed here. Please visit his website: http://member.netease.com/~gmounto/cpro/BAT2COM.html

A forum user wang6610 reminded me today that the link in post 1 has expired. It might be that the original link was changed or the space was closed because the author didn't pay. Fortunately, I have a backup of the source program, and now I'll post it for everyone to study and research.

Recently I discovered a C language original code that converts BAT files to COM. After compilation, the effect is good. The converted COM file is much smaller than the one converted by BAT2COM, and the execution efficiency is also faster. To respect the original author's copyright, the source program is not listed here. Please visit his website: http://member.netease.com/~gmounto/cpro/BAT2COM.html
