  - PM69337 for IMS DEDB Fast Recovery
  A logger exit routine (DFSFLGX0) is passed a standard user exit
  parameter list of a back level when it is called from DFR.
  DFR passes the version 4 standard user exit parameter list
  instead of the version 6.
  

Problem conclusion

Temporary fix

Comments

• The following field is added to a standard user exit parameter
  list in version 5:
   - SXPLASCD (SCD Pointer)
      This field is a pointer to the SCD.
  *
  The following fields are added to the standard user exit
  parameter list in version 6:
   - SXPLASWA (Static Work Area Pointer)
      This field is a pointer to a static work area
      associated with this exit routine.  If there
      are multiple exit routines for a given exit
      types, each exit routine has its own static
      work area.
   - SXPLIMSR (IMS Release Pointer)
      Pointer to a 4 byte field that contains the release
      of the IMS that is calling the exit routine.
   - SXPLIMID (IMS ID Pointer)
      Pointer to a 4 byte field that contains the IMS
      ID of the IMS that is calling the exit routine.
   - SXPLRSEN (IMS RSE Name Pointer)
      Pointer to a 4 byte field that contains the RSE
      of the IMS that is calling the exit routine.
   - SXPLCNXT (Ptr to Call Next Exit Indicator byte)
      Pointer to a byte in storage that contains a flag
      that indicates if the next exit is to be called.
      SXPL_CALLNXTN - Don't call next exit
      SXPL_CALLNXTY - Call the next exit
   - SXPLFLGA (Ptr to flag word 1)
      Pointer to a word in storage that contain flags.
      Only the first byte is currently used.
      Flag byte 1:
        SXPL_F1ENHSRV - Exit called using enhanced services
  *
  The following fields are set to zero when a logger exit routine
  (DFSFLGX0) is called from DFR because the data they normally
  contain is not available in the DFR environment as well as the
  log recovery utility:
  *
    SXPLASCD
    SXPLRSEN
    SXPLCNXT
    SXPLFLGA
  *
  The following modules have been modified.
  (x = B and C)
  *
  DFRNLGEx - This module was changed so that the version 6 of SXPL
             might be passed when it calls the logger exit routine
             (DFSFLGX0).
