For an easy way to execute commands from a C program, try the system()
function.  It calls HPCICOMMAND for you, and you don't have to append a
carriage-return.

You can even use it to execute a RUN command, so you might not need to
use CREATEPROCESS.

Here's a sample program.

-----cut here-----
#include <stdio.h>
#include <stdlib.h>
int main(void)
{
   int return_value;
   /* Invoke our favorite text editor */
   return_value=system("RUN EDITOR.PUB.SYS");
   if (!return_value)
      {
      puts("Everything is fine!");
      return EXIT_SUCCESS;
      }
   else
      {
      puts("*** OOPS! ***");
      return EXIT_FAILURE;
      }
}
