              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
