Problem summary

  • ****************************************************************
    * USERS AFFECTED: Enterprise COBOL V5.1 users who are          *
    *                 using the Procedure Pointer feature to       *
    *                 make dynamic calls into subprograms.         *
    ****************************************************************
    * PROBLEM DESCRIPTION: When comparing with COBOL V4.2 there    *
    *                      was a higher overhead in handling       *
    *                      Procedure Pointers in COBOL V5.1.       *
    *                      As a result, subroutine calls using     *
    *                      Procedure Pointers gave less            *
    *                      performance than COBOL V4.2             *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    COBOL V5.1 took a longer code-path in handling
    Procedure Pointer calls, giving less performance
    when comparing with COBOL V4.2.
