: To call a C program from a IDL one, you can use the CALL_EXTERNAL
: function for IDL, and put your C program into a DLL.
: In your DLL, you can spawn another process...

: E.G.

You could also spawn your C program in the background
with something like: SPAWN, 'c_program &'
This can also be used to make a link to your external
and make an I/O connection between IDL and the C program.
