  ****************************************************************
  There is a possibility of ABEND0C4 in CSECT FABPUMAP when all of
  the following conditions are met:
  - HDPC with HASH=NO and EPSCHK=YES is run for HALDBs in a
    stand-alone (FABPMAIN) job.
  - The HALDBs have logical relationships or PSINDEXes.
  - The target segments are split.
  
  When the area that contains the data part of the split segment
  is close to the beginning of the boundary of the I/O buffer,
  HDPC gets ABEND0C4 because HDPC erroneously attempts to handle
  the data part of split segments as the prefix part.
  

Problem conclusion

• The FABPUMAP module has been modified to fix the error.
