DDRREC Prolog
NAME : DDRREC
DESCRIPTION: DYNAMIC RECONFIGURATION RECORD
DSECT : DDRREC
FUNCTION : DDRREC IS USED IN SVC 76 INITIATED ERROR
RECORDING PROCESS FOR TYPE 60 DASD DUMP
RESTORE (DDR) DYNAMIC DEVICE REALLOCATION
RECORDS. THE REALLOCATION RECORDS CONTAIN
THE REPLACEMENT OF THE VIRTUAL "FROM" AND
"TO" CONTROL UNIT ADDRESSES (CUA) BY THE
REAL ADDRESSES OF THE REAL DASD DEVICES.
LOCATED BY : GPR9 IN HCPVER. THE ADDRESS IS PASSED TO
HCPIOE AND HCPREC IN GPR1.
CREATED BY : GUEST; COPIED TO FREE STORAGE BY HCPVER.
DELETED BY : HCPIOE AFTER HCPREC HAS COPIED IT INTO
A GSDBK.
