C programming problem

The Question is:

Hi! I confess I'm pretty new to programming in C for
OpenVMS so my questions are pretty basic.  I did check the
FAQ and search first with no luck.

First off what to I need to include in order to use
SYS$CRMPSC? Next I need to call a completely separate
program (.EXE) from within my C program and then return.
I've been unable to find the solution.  Any assistance
appreciated.

Thanks.

The Answer is:

DEC C provides a complete documentation set, with an extensive section on
system programming.  Please refer to the manuals for details.

To run a program, use the "system" routine, as documented in the DEC C Run-Time
Library Reference Manual.
