MCHREC Prolog
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
VM/XA DOES NOT CONTROL THE DEFINITIONS NOR DOES IT
NECESSARILY USE ALL THE FIELDS DEFINED OR ALL THE BITS
DEFINED WITHIN A FIELD.
EACH PROCESSOR HAS ONE OF THESE BLOCKS PRE-ALLOCATED BY
HCPMPS DURING PROCESSOR INITIALIZATION FOR USE BY
HCPMCH. THIS BLOCK IS POINTED TO BY MCKREC IN MCKBK.
