  * USERS AFFECTED: All CICS users                               *
  ****************************************************************
  * PROBLEM DESCRIPTION: The WMQ Get Fast Wait processing logic  *
  *                      for a PUT1 request fails with abend     *
  *                      S0C4-10 in a system where TRANISO=YES   *
  *                      is specified.                           *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  Attempts by a WMQ Putter task to insert a message into a WMQ Get
  Fast Waiter's input buffer fail with an S0C4-10 abend when
  TRANISO=YES is specified. This is because, when transaction
  isolation is active, CICS switches the application doing the
  PUT1 into a subspace which does not have access to the buffer
  of the application doing the GET.

Problem conclusion

• A test has been inserted prior to the MQPUT1 logic in DFHMQTRU
  to see whether or not transaction isolation is active.
  If it is, a subspace switch back to basespace is made prior to
  the MQPUT1, with another switch back to subspace upon return
  from the MQPUT1 call.
