PRLOG Prolog

 NAME       : HCPPRLOG
 DESCRIPTION: layout for prolog at beginning of module
 DSECT      : PRLOG
 FUNCTION   : allows fields within the prolog to be referenced by
              name
 LOCATED BY : the module base register (R12) points to the
              HCPPRLOG which resides at location 0 in
              the module.
 CREATED BY : the HCPPROLG macro at assembly time
 DELETED BY : none
 SERIALIZED : none
