     NAME       : HCPLGPBK
     DESCRIPTION: HCPUSODC and HCPUSORF Parameter List
     DSECT      : LGPBK
     FUNCTION   : Pass parameters to HCPUSODC and HCPUSORF
     LOCATED BY : The address of this control block is passed as
                  input to HCPUSODC and HCPUSORF.
     CREATED BY : HCPUSOFL, HCPLOGON, HCPCFMFO, HCPSASRE, HCPSASSC
     DELETED BY : HCPUSODC, HCPUSORF
     SERIALIZED : Task Ownership.
                  This control block is created, used and deleted
                  by entry points involved in FORCE processing.
                  Access to this control block is not made
                  available to any other task.
