Hi Todd,

As I understand it, you basically need to follow these steps:

1) Ensure gcc is correctly installed on your machine - it sounds like it
probably is on yours, since it compiles to a.out at all.
2) CD to the directory where your C source files reside
3) Write or locate your source code, eg. <testprog.c>
4) From shell, type   gcc -o <testprog> <testprog.c>   [enter]

This will directly create the binary executable 'testprog' from the source
code 'testprog.c' .  I find it clearer to give executable files a name
immediately, other than the default 'a.out' every time.

You can then run it from the shell by typing ./testprog  (that's
dot,slash,testprog [enter] - at leat that works for me in Linux Mandrake).

Best wishes,
