*****************************************************************

*---------------------------------------------------------------*
* This program activates service program SRVPGM1, which has
* procedure Proc1.
* A pointer to Proc1 is then recovered, and Proc1 is executed.
*
* Note that SRVPGM1 needn't be listed as a BNDSRVPGM when
* this program is created.
