Problem conclusion

• DFHPGIS has been modified to validate the control blocks
  which belong to the task which is being inquired upon before
  referencing the storage.
  Note that if a bad pointer is encountered while validating
  control blocks, an 0C4 in DFHPGIS may be recorded in Kernel
  Error Data.
