  - PM53347 for IMS DEDB Fast Recovery
  Even if there is a block sequence number gap between the OLDS
  and the WADS, DFRFDLWC does not set RLWSB (X'06') to RLWRSNP
  field. When the value in RLWRSNP field is except X'06', DFRGCLSC
  uses this value to set an error type to a MSGDFR3100E message.
  As a result, a garbage data is set to the MSGDFR3100E message as
  follows:
  .
   +DFR3100E FSWADS1"""" ERROR IN WADS DDNAME=DFSWADS1
             ===========
  .
  If DFR encounters a block sequence number gap between the OLDS
  and the WADS, DFR must issue MSGDFR3105E message and end with
  abend code of U3105.
  

Problem conclusion

Temporary fix

Comments

• The following module has been modified.
  *
  DFRFDLWC - This module was changed so that RLWSB (X'06') might
             be set to RLWRSNP field when it encounters a block
             sequence number gap between the OLDS and the WADS.
