X'112C' INIT/CLEANUP - ISWITCH FAILURE

Explanation
 Either an ISWITCH to the CTL region or an ISWITCH
RETURN to the MRQ/QCF dependent region failed.                   

Programmer response
  Save area QMRWESAV in MRQWORK contains
the registers at the time of the error (R0 - R15). R15 is the ISWITCH
error code.  R1 is the module ID that was issuing the ISWITCH. 
QMR1 = DFSQMR10

QMR7 = DFSQMR70

QMR9 = DFSQMR90

If flag QMRWFLG9=QMRW9SWI is off, this indicates this is an ISWITCH
to the CTL region failure. If flag QMRWFLG9=QMRW9SWI is on, this is
an ISWITCH RETURN to the MRQ/QCF dependent region failure. This is
an internal IMS error.
