Example: Run an i5/OS PASE program from within i5/OS programs

The examples illustrated in this topic show an ILE program that calls an i5/OS™ PASE program, and the i5/OS PASE program that is called by the ILE program.

#include <stdio.h>
#include <string.h>
#include <stdlib.h>
#include <stdio.h>
#include <unistd.h>

/* include file for QP2RunPase(). */

#include <qp2user.h>
