  ****************************************************************
  * RECOMMENDATION: Apply the maintenance for this APAR.         *
  ****************************************************************
  HD Pointer Checker erroneously attempts to refer to an ILK value
  in a data part of an index source segment, although there is
  no ILK field in the data part. There is a possibility of
  ABEND0C4 in the process.
  

Problem conclusion

• The module FABPSSUP has been modified not to refer to an ILK
  value when processing a data part of an index source segment.
  

Temporary fix
