Hi!
    I'm trying to make a DOS "shell", to improve the limited COMMAND.COM function.

    In order to reduce memory usage, I need help...

    Does one of you:

Turbo Pascal V1.0, 2.0
 
There is a DOS INT 21 function to do that.  Check a DOS reference manual.
Thanx for your help
 
Good luck.

The program to beat is 4DOS from JP Software.  It is the best. In fact, it's so good, I see no reason to replace it.  Their tech support is great too.
