Problem summary

  • ****************************************************************
    * USERS AFFECTED: Users of Enterprise COBOL 6.1 compiling and  *
    *                 running programs that contain INSPECT        *
    *                 statements.                                  *

    ****************************************************************
    * PROBLEM DESCRIPTION: Runtime performance: Certain INSPECT    *
    *                      statements take longer to execute in    *
    *                      COBOL 6.1 than in COBOL 4.2.            *
    *                                                              *

    * RECOMMENDATION: Apply the provided PTF.                      *
    *                                                              *
    ****************************************************************
    The algorithm used to implement INSPECT in COBOL 5 is slower on
    certain cases.
    

Problem conclusion

  • The algorithm was changed to improve performance for INSPECT
    statements.
