 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
