APAR status

• Closed as program error.

Error description

• HDPC incorrectly issues MSGFABP2023E and MSGFABP2024E on the
  following conditions:
  1. HDPC runs for an HDAM or a HIDAM database and its associated
  index databases.
  2. HASH=NO and IXKEYCHK=YES are specified in the PROCCTL data
  set.
  3. The HDAM or HIDAM database uses OSAM access method and the
  database data set has an even-length block size.
  4. The HDAM or HIDAM database is used with the following two
  kind of index databases:
  
     1). A HIDAM primary index, or a secondary index using a
  direct pointer(The index target segment and the index source
  segment are the same segment.)
     2). A secondary index using a symbolic pointer, or a
  secondary index using a direct pointer(The index target segment
  and the index source segment are different segments.)
  
  5. Some index source segments are split into the prefix and the
  data portions.
  6. The prefix and the data portions reside in blocks that are
  beyond the 4 GB and they do not reside in the same block or the
  adjacent blocks.
