  * PROBLEM DESCRIPTION: The EXTRACT function of CSQ1LOGP can    *
  *                      produce incorrect information when      *
  *                      units of work contain failed MQPUT      *
  *                      operations for large persistent         *
  *                      messages.                               *
  ****************************************************************
  During the MQPUT of a message an error was detected after the
  IRHA pages for the message had been logged, but before the IRH8
  or IRH9 had been logged, and the operation was correctly
  undone.
  However when CSQ1LEXT processes the log records, it does not
  correctly detect that the IRHA pages were part of a failed and
  undone operation, causing these pages to be attributed to the
  following message in the unit of work.
  

Problem conclusion

• CSQ1LEXT is changed to correctly skip log records representing
  IRHA records for MQPUTs that failed.
