Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• 1. High Performance Load incorrectly handles X'FF' segment which
  is defined as fixed compressed segment.

  *                          incorrect if following condition    *
  *                          is satisfied:                       *
  *                           - variable length or fixed         *
  *                             compressed segment.              *
  *                           - some segments are placed in the  *
  *                             SEQERROR DD data set.            *
  *                           - the length of segments in        *
  *                             sequence error is not grater     *
  *                             than MIN length.                 *
  ****************************************************************
  * RECOMMENDATION: Apply the maintenance for this APAR.         *
  ****************************************************************
  (1) If the fixed length segment is compressed, High Performance
      Load adds 2 bytes to the length of X'FF' segment for every
      partition. Processing 2nd partition or after, the length of
      X'FF' segment is incorrect.
  (2) High Performance Load incorrectly reports LENGTH OF MAX in
      the VARIABLE LENGTH SEGMENT STATISTICS report for HIDAM or
      PHIDAM, because it incorrectly adds 2 bytes to the value
      for every partition.
  (3) High Performance Load incorrectly reports OCCURRENCES
      (VERSUS MIN) in the VARIABLE LENGTH SEGMENT STATISTICS
      report, the problem might occur when:
       - variable length or fixed compressed segment.
       - some segments are placed in the SEQERROR DD data set.
       - the length of segments in sequence error is not grater
         than MIN length.
      The reason of this problem is that the formula for
      calculating each OCCURRENCES is incorrect.
  

Problem conclusion

• HP Load utility has been modified as follows:
  - Modify HPSRHDL6, HPSRHDLD7, HPSRHDL8, HPSRHSL6, HPSRHSL7,
    HPSRHSL8, HPSRRLD7 and HPSRRLD8
    to handle X'FF' segment, and to report the VARIABLE LENGTH
    SEGMENT STATISTICS correctly.
