     NAME       : HCPLBPBK
     DESCRIPTION: LOADBUF Parameter Block
     DSECT      : LBPBK
     FUNCTION   : Passes the information needed by HCPCSB to
                  load a Forms Control Buffer or a Universal
                  Character Set in from the specified image
                  library.
     LOCATED BY : R1 on entry to HCPCSBIN.
     CREATED BY : HCPCSS  -  START command
                  HCPLBF  -  LOADBUF command
                  HCPRSP  -  Real printer processing
     DELETED BY : HCPCSS  -  After return from HCPCSB
                  HCPLBF  -  After return from HCPCSB
                  HCPRSP  -  After return from HCPCSB
