*     2. FUNCTIONAL DESCRIPTION 
*        CREATE AND SEND SUPEVISORY MESSAGE REG/CP TO PIP 
* 
*     3. METHOD USED
*        CALL MGETS TO GET BUFFER FOR REG/CP
*        CREATE REG/CP SUPERVISORY MESSAGE, THE DATA BLOCK
*        HEADER, AND THE APPLICATION HEADER.
*        SEND REG/CP SM TO THE SPECIFIC COUPLER IF PARAMS1 IS NON-ZERO, 
*        OTHERWISE, TO ALL ACTIVE COUPLERS. 
* 
*     4. ENTRY PARAMETERS 
*        PARAMS1             COUPLER NODE 
*                            FOR ALL ACTIVE COUPLERS, PARAMS1 IS ZERO.
*        PARAMS2             NETWORK BLOCK HEADER ADDRESS 
* 
*     5. EXIT PARAMETERS
*        PARAMS1             SET TO 1 IF NETWORK HEADER IS GARBLED. 
* 
*     6. COMDECKS CALLED

* 
*        THIS PROGRAM IS A SECONDARY OVERLAY LOADED BY SUBROUTINE 
*        OVLCALL. WHEN EXECUTION HAS COMPLETED, A JUMP IS MADE TO 
*        LOCATION RJMAIN TO RETURN TO THE CALLING PROGRAM.
* 
*        W A R N I N G - THIS PROGRAM CANNOT EXCEED THE SECONDARY 
*CALL OSSIZE
* 
*        THIS OVERLAY IS CALLED BY HPNONSA,NPREGCP,NPREGST.
