MCRBK Prolog
NAME : HCPMCRBK
DESCRIPTION: Machine Check Record Block
DSECT : MCRBK
FUNCTION : HCPMCRBK contains information relative to a
machine check incident which (incident) is to be
reflected to a guest.
LOCATED BY : Is a mapping of the parameters passed for
manufacturing a machine check or building the
message information when communicating a machine
check incident.
CREATED BY : Any caller who wants to pass a machine check record
information.
DELETED BY : The caller who creates it or the callee. This is
communicated via MCRFLAG1 in this control block.
