Since I don't see any other posts, I'll post and maybe save you some
mail.

The easiest thing to do is use system(3). Since you're new to UNIX, this
means the system command in section 3 of the man pages. If you want to
see the man page entry for this, type 'man 3 system' (without the
quotes).

You might also want to look at fork(2V) (use 'man 2 fork', not 'man 2V fork')
and execl(3V).
