     NAME       : MCHREC
     DESCRIPTION: MACHINE CHECK ERROR RECORD
     DSECT      : MCHREC
     FUNCTION   : MCHREC PROVIDES MACHINE CHECK INFORMATION
                  FOR ERROR RECORDING.
     LOCATED BY : PFXMCHA FIELD IN  PFXPG.  ALSO POINTED
                  TO BY GPR6 IN HCPIOE, AND PASSED TO
                  HCPREC IN GPR1.
     CREATED BY : HCPMPS AT INITIALIZATION FOR EACH CPU.  A
                  COPY IS MADE BY HCPMCH FOR ERROR RECORDING.
     DELETED BY : HCPIOE AFTER HCPREC HAS COPIED IT INTO GSDBK.
                  IF A CPU IS VARIED OFF, THEN IT'S MCHREC IS
                  DELETED BY HCPMPS.
     RELOCATION CONSIDERATIONS : None

           THIS CONTROL BLOCK IS AN INTER-OPERATING-SYSTEM BLOCK
           WHICH IS DEFINED BY IBM CORPORATE STANDARDS. THEREFORE

           NECESSARILY USE ALL THE FIELDS DEFINED OR ALL THE BITS
           DEFINED WITHIN A FIELD.
             EACH PROCESSOR HAS ONE OF THESE BLOCKS PRE-ALLOCATED BY
