  ****************************************************************
  The code in IGZCCTL references a PCONTROL address which was
  saved during a previous call. When the previous call was for a
  GOBACK, CANCEL or as part of run unit termination, the PCONTROL
  storage has most likely been freed when control returns to
  IGZCCTL again.
  

Problem conclusion

• IGZCCTL is modified to clear the PCONTROL address in cases
  where the PCONTROL is likely to have been freed before IGZCCTL
  is called again.
