- JCL PARM
//SAMPPROG EXEC PGM=XXXXXXXX,PARM='XXXXXXXX......'
CONTAINS A PARM FIELD WITH UP TO 100 BYTES OF DATA IN IT.
THE PROGRAM BY DESIGN PICKUPS UP A POINTER TO THE DATA AND
THE DATA LEN. REG 1 HAS WHAT YOU NEED TO EXTRAPOLATE ALL OF
THIS.
- PASS DATA TO CALLED PROGRAM
IN THIS CASE, CALLER IS AN ALC PROGRAM PASSING 2 FIELDS TO
SUBROUTINE NAMED SUBROUT1. THE PASSED FIELDS WILL HAVE BEEN
PRIMED PRIOR TO THE "CALL"
