China DOS Union

TC2.0 provides a system() function. This function can execute
commands in DOS and COMMAND.COM from within a running C program. By using this function, we can very conveniently convert batch files
into executable files. The method is as follows:
For example, the batch file Sample.bat
c:
cd c:\dos
dir/p
The corresponding C program is as follows:
Sample.c
#include //the system() function is included in this library
main()
{
system("c:");
system("cd c:\dos");
system("dir/p");
}
Compile Sample.c into an executable file, and running this file will achieve the function of Sample.bat.

It works, but doing it this way means every time you call a command you have to load a copy of command.com.
In actual use it probably isn't as good as tools like BAT2EXE.

BAT2EXE is probably also written in C, right? I don't know, but in a few months I will know

Because I once saw a section of C code called typeWps that could directly display WPS document files,
I think this and BAT2EXE may be somewhat similar in concept.


Work hard.....work even harder, I also want to emulate a BAT2EXE

Thank you.

COMMAND.COM is the command interpreter. Doesn't BAT2EXE also need a command interpreter?

If that's really the case, then I'll have to study compiler theory. A few months may not be enough, maybe a year .


If I've written anything wrong, please point it out to me.

Thanks, everyone.

Give this a try. If it can be made resistant to cracking, it should turn out quite well.

The system approach is pure wishful thinking

Labels won't work, variables won't work, and there are a whole bunch of other problems

Every time the system function is executed, it creates a command process to run it, and destroys it as soon as it finishes, leaving nothing behind

This approach doesn't have much value anymore...
