  - PM52014 for IMS DEDB Fast Recovery
  DFRGCLSC sets a value taken from the last X'4800' log record as
  a value of RLGWMAT field in the parameter list (RLWPSUFX) passed
  to DFRFDLWC and reflects the WADSs allocation status to WADSID
  in RLGWMAT field.
  If a secondary WADS is allocated but a primary WADS is not in
  a dual WADS environment, the first byte of WADSID in RLGWMAT
  field is X'00'.
  DFRFDLWC was rewritten for IMS V12 and no longer supports or
  requires special handling of PAWADSB in the last good block
  suffix passed by DFRGCLSC.
  DFRFDLWC now assumes that PAWADSB has the value it had during
  IMS execution where the primary WADS ID must always exist and so
  it would return with a no record found condition if the primary
  WADS ID was zero.
  

Problem conclusion

Comments

• The following module has been modified.
  *
  DFRGCLSC - This module was changed so that the WADSs allocation
             status of DFR might not be reflected to WADSID in
             RLGWMAT field.
