  *                 users who run HD Pointer Checker (HDPC).     *
  ****************************************************************
  * PROBLEM DESCRIPTION: This APAR enables HDPC to detect RBAs   *
  *                      that are beyond EOF in HD databases.    *
  ****************************************************************
  * RECOMMENDATION: Apply the maintenance for this APAR.         *
  ****************************************************************
  By this APAR, HDPC has been enhanced to check whether physical
  pointers in HD databases point beyond the end of file (EOF) of
  each database data set.
  
  If the pointers that point beyond EOF are detected, HDPC prints
  a new message FABP1071E to the VALIDATION OF A POINTER TO A
  TARGET AT CHECK REPORT or the HASH Evaluation report. This
  message is also printed to the HD Pointer Checker Message
  Summary report.

   <The following message has been added:>>
  
  FABP1071E POINTERS THAT POINT BEYOND EOF WERE DETECTED. THE
  DATASET SIZE IS X'xxxxxxxx'.
  
  Explanation: The database data set or the image copy data set is
  damaged. The physical pointers that point beyond the End Of File
  (EOF) of the database data set were detected. The size of the
  data set is xxxxxxxx bytes in hexadecimal. The values of the
  pointers are beyond xxxxxxxx.
  If the size of the data set is between 4 GB and 8 GB, the value
  of the data set size is expressed by incrementing the last bit
  by 1. For example, if the data set size is 4.5GB, the value is
  printed as X'20000001'.
  
  As the cause of this error, the following reasons can be
  considered:
   - The physical pointers are damaged.
   - The database data set or the image copy data set has an
     incorrect EOF.
  System Action: Processing continues.
  User Response:    Repair the database. If the database data set
  or the image copy data set has an incorrect EOF, you can repair
  the error by reorganizing the database. After repairing the
  database, rerun the HD Pointer Checker job.
  Problem Determination: See "Database repair guidelines" in topic
  2.9.
