MITREC Prolog
NAME : MITREC
DESCRIPTION: 370/XA MODE MISSING INTERRUPT RECORD
DSECT : MITREC
FUNCTION : MITREC IS USED IN THE SVC 76 INITIATED ERROR
RECORDING PROCESS OF TYPE 71 MIH (MISSING
INTERRUPT HANDLER) RECORDS FOR XA GUESTS.
LOCATED BY : GPR9 IN HCPVER. THE ADDRESS IS PASSED TO
HCPIOE AND HCPREC IN GPR1.
CREATED BY : XA GUEST; COPIED TO FREE STORAGE BY HCPVER.
DELETED BY : HCPIOE AFTER HCPREC HAS COPIED IT INTO
A GSDBK.
