Well... you need to define the problem more completely.
Ada can do all of the things a C program can do. For example, it can execute
a shell command via the "system" C-library function, or "fork," wait for child
process completion, etc., etc.
Here are (at least some of) the questions that need to be answered, viz.:
1. Do you need to wait until the UNIX command completes before proceeding?
2. Do you need results from the UNIX command to be used in your continued processing?
3. If the answer to (2.) is "yes," are these results binary or text, and how do you
propose to communicate them?
4. You speak of "UNIX command" and "another program." Are these terms as used by you
synonymous?
