  HDPC incorrectly detects an index key error and issues
  MSGFABP2023E and MSGFABP2024E under the following conditions:
  
  - IXKEYCHK=YES and HASH=NO are specified in the PROCCTL
    statement.
  - An index target segment type is different from an index source
    segment type.
  - A segment occurrence of the index target segment type is
    located beyond 4 gigabytes.
  
  In this case, HDPC creates the incorrect records for the Index
  Key Check in the IXKEY data set.
  

Problem conclusion

• The module FABPSIX0 has been changed to create the correct
  records for the Index Key Check in the IXKEY data set.
  

Temporary fix
