I want to write a program that would invoke other commands on the system (ex: dir (dos) or ls(unix)). Can someone give me a hint on how to get this done? Thanks in advance.

The only portable way is to use the system() function which is part of the C run-time library.  There are some non-portable ways that may provide you with more control/options however.

Let me know if you have questions.

Hi nietod - you're typing fast ;-)
Well, this usually can be done using the 'system()' command.
However, if you specialize on a certain platform (e.g. UN*X, NT, Win9x) there are eventually more sophistcated wayd to do this (NOTE: 'dir' in DOS is a built-in shell command, you'll have to use the command line 'command.com /k dir').
