Problem summary

• ****************************************************************
  * USERS AFFECTED: Users debugging Enterprise COBOL V3 or V4    *
  *                 programs with Debug Tool in remote debug     *
  *                 mode.                                        *
  ****************************************************************
  * PROBLEM DESCRIPTION: When Debug Tool remote debug is used    *
  *                      to monitor an array in the linkage      *
  *                      section and the storage is not          *
  *                      available after the first array         *
  *                      item, a significant amount of           *
  *                      CPU time can be used.                   *
  ****************************************************************
  * RECOMMENDATION: Apply the provided PTF.                      *
  ****************************************************************
  The COBOL runtime did not stop the processing of array elements
  when an array element was not in storage. It processed every
  array element checking to see if the storage was available.
  When the storage was not available, a program check would occur
  and the COBOL runtime would handle the program check with the
  the Language Environment shunt support. The overhead of many
  program checks and recovery caused a significant amount of CPU
  time to be used when there were a large number of array
  elements that were not in storage.

Problem conclusion

• The COBOL runtime was changed to stop the processing of
  array elements when it encounters an element that is not
  in storage.
