  ****************************************************************
  ABEND0C4 occurs in CSECT FABPIC20 around offset X'C00' or
  MSGFABP3913E and ABENDU3913 are incorrectly issued when the
  following image copies are used as input to stand-alone HD
  Pointer Checker (HDPC) jobs:
  - Database Image Copy 2 (IC2) image copies (SMSNOCIC and SMSCIC
    type image copies) of databases that have extended format
    VSAM data sets such as for encryption and in compressed format
  - Database Image Copy 2 (IC2) image copies that were created
    with the ZCOMPRESS option of the DFSMSdss DUMP command
  

Problem conclusion

• HD Pointer Checker (HDPC) does not support the following image
  copies so HDPC has been modified to issue MSGFABP3925E and
  ABENDU3925 when using such image copies as input.
  - SMSNOCIC and SMSCIC type image copies of encrypted database
    data sets and extended format data sets in compressed format
  - Database Image Copy 2 (IC2) image copies that were created
    with the ZCOMPRESS option of the DFSMSdss DUMP command

  IMS High Performance Pointer Checker for z/OS, V3R1, User's
  Guide (SC19240107) is modified as follows:
  ================================================================
  > HD Pointer Checker utility
  >> Using the HD Pointer Checker processor
  >>> Restrictions and considerations
  >>>> Restrictions when using image copy data sets as input
  ----------------------------------------------------------------
   The following restrictions apply when the input to the HD
   Pointer Checker is an image copy data set.
   - HD Pointer Checker accepts the following types of image copy
     as input database data set:
     - A batch image copy
     - A compressed batch image copy taken with IMS HP Image Copy
     - An SMSNOCIC type image copy and an SMSOFFLC type image copy
  |    (Exceptions: SMSNOCIC type image copy of an encrypted
  |     database data set and extended format data set in
  |     compressed format are not supported.)
     - A Fast Recovery image copy taken with IMS HP Image Copy
       4.1 or later
   - HD Pointer Checker can process the following image copies.
     However, if the database is updated while image copy is being
     taken, HD Pointer Checker might detect pointer errors even if
     there are actually no pointer errors.
     - An online image copy
     - A concurrent image copy taken by a batch image copy or IMS
       HP Image Copy
     - An SMSCIC type image copy and an SMSONLC type image copy
  |    (Exceptions: SMSCIC type image copy of an encrypted
  |     database data set and extended format data set in
  |     compressed format are not supported.)
   - HD Pointer Checker does not support Database Image Copy 2
     (IC2) image copy data sets that have the following
     characteristics:
     - Contain multiple image copies
  |  - Contain data that is compressed with the ZCOMPRESS option
  |    of the DFSMSdss DUMP command
     For more information about online image copy and concurrent
     image copy, see HD Pointer Checker online considerations.
  - If the input to the HD Pointer Checker is a batch image copy
     data set created from an OSAM LDS data set, HD Pointer
     Checker assumes that the OSAM LDS data set has the extended
     addressability attribute defined and determines the size
     limit for the database data set.

   FABP3925E DUMPED DATA SET IS UNSUPPORTED FORMAT
             - text
   Explanation
  |The organization type of the dumped database data set is not
   supported. text provides additional information:
   - FOR OSAM DATA SET, BLOCKED RECORD
   - FOR VSAM DATA SET, NOT ESDS/KSDS
   - FOR VSAM DATA SET, SPANNED RECORD
   - FOR DEDB/HDAM/HIDAM DATA, BLOCKED RECORD
  |- DATA SET IS ENCRYPTED
  |- EXTENDED FORMAT DATA SET IN COMPRESSED FORMAT
  |- DATA IS COMPRESSED WITH THE ZCOMPRESS OPTION OF THE DFSMSDSS
  |  DUMP COMMAND
   System action
   HD Pointer Checker issues a USER 3925 abend.
   User response
   Ensure that the correct data set is specified and that the data
   set is not broken. Also, ensure that the DD statement specifies
   the correct data set. Correct the errors and rerun the job.
  |If either of the following image copies are used as input, you
  |must recover the databases from the image copies and run HD
  |Pointer Checker for the recovered databases.
  |- SMSNOCIC or SMSCIC type image copies of encrypted databases
  |- Database Image Copy 2 (IC2) image copies that were created
  |  with the COMPRESS option of the Database Image Copy 2 utility
  |  and the ZCOMPRESS option of the DFSMSdss DUMP command
