     NAME       : HCPSIDBK
     DESCRIPTION: SYSTEM ID LIST
     DSECT      : SIDBK
     FUNCTION   : CONTAINS THE SYSTEM ID FOR EACH PROCESSOR
                  UPON WHICH THE SYSTEM IS EXPECTED TO BE
                  IPL'D.  THIS ID WILL APPEAR ON THE LOGO
                  PRIOR TO LOGGING ON A USER AND ON SEPARATOR
                  PAGES OF SPOOLED PRINTER OUTPUT.
     LOCATED BY : SYSIDL FIELD OF HCPSYSCM
     CREATED BY : HCPSYS ASSEMBLY (SYSGEN) IF THERE IS A SYSID
                  MACRO and HCPZPP if there is a SYSTEM_ID
                  in the SYSTEM CONFIG file.
