 NAME       : MIRREC
 DESCRIPTION: 370 MODE MISSING INTERRUPT RECORD
 DSECT      : MIRREC
 FUNCTION   : MIRREC IS USED IN THE SVC 76 INITIATED ERROR
              RECORDING PROCESS OF TYPE 70 MIH (MISSING
              INTERRUPT HANDLER) RECORDS FOR 370 GUESTS.
 LOCATED BY : GPR9 IN HCPVER.  THE ADDRESS IS PASSED TO
              HCPIOE AND HCPREC IN GPR1.
 CREATED BY : 370 GUEST; COPIED TO FREE STORAGE BY HCPVER.
 DELETED BY : HCPIOE AFTER HCPREC HAS COPIED IT INTO
              A GSDBK.
