  WLR does not route message switches for non-modifiable PCBs.
  Prior to the introduction of the DFSMSCE0 exits, WLR used
  exit DFSCMPR0 for program-to-program routing for modifiable
  PCBs. Non-modifiable PCBs were not passed to the DFSCMPR0 exit.
  With the introduction of the DFSMSCE0 exit, IMS provides two
  program routing exit points (PRCHNG and PRISRT). WLR currently
  receives control in the DFSMSCE0 PRCHNG exit point. This exit
  point only receives control on a 'CHNG' call. Since non-
  modifiable PCBs do not issue 'CHNG' calls, WLR does not receive
  control for these requests and cannot route them.
  

Problem conclusion

• WLR is being enhanced to receive control in the DFSMSCE0
  PRISRT exit point instead of the PRCHNG exit point. This
  will allow WLR to route message switches to both modifiable
  and non-modifiable PCBs. The PRISRT call receives control
  on the 'ISRT' call instead of the 'CHNG' call.
