Problem summary

  • ****************************************************************
    PROBLEM DESCRIPTION:  When attempting to open Show this COBOL
    program in the Program Control Flow the complex logic of this
    particular program caused the maximum number of iterations for
    the control flow determination algorithm to be exceeded.
    ****************************************************************
    

Problem conclusion

  • ****************************************************************
    Problem Resolution: The control flow determination algorithm was
    modified to account for the complexity of this program so that
    it could be shown in the Program control Flow view.
    
    ****************************************************************
    
    The problem listed in this APAR has been resolved with
    IBM Rational Developer for System z V9.1.1.4 Fix Pack which
    is available from the Recommended Fixes support download page:
