0000 0 Structure MCHREC MACHINE CHECK ERROR RECORD
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.
