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.
 RELOCATION CONSIDERATIONS : None
