Error description

• Rational Developer for System z - RDz - v8.5
  CRRZJ004E happens during display of  the 'Program Control Flow
  Diagram' for a COBOL program file.
  This error happens when the source code contains any of these
  optional phrases:
  - ON SIZE ERROR phrase on the ADD, COMPUTE, DIVIDE, MULTIPLY,
  and SUBTRACT statements
  - ON OVERFLOW phrase on the CALL and STRING statements
  - AT END phrase only in RETURN statement
  The error may result in either a CRRZJ004E error as indicated
  above, or just incorrect results of the feature, depending on
  the source code around the phrases with the error.
  This error may happen for both 'Show In ? Program Control Flow'
  and 'Source ? Identify Unreachable Code' features.
  

Local fix

Problem summary

• The phrases listed in the APAR description all affect control
  flow, but were not passed into the control flow walk algorithm.
   This caused a variety of problems, from CRRZJ004E errors to
  incorrect results, depending on how the COBOL statements using
  these phrases were used within the COBOL program.   Both the
  Program Control Flow diagram, and the Identify Unreachable Code
  feature are affected.
  

Problem conclusion

• These listed phrases are now correctly passed into the internal
  control flow walk algorithm to avoid the described problems.
  
  The problem listed in this APAR has been resolved with
  IBM Rational Developer for System z V8.5.1 Refresh Pack which
  is available from the Recommended Fixes support download page:
