Problem summary

  • ****************************************************************
    * USERS AFFECTED: Users of Enterprise COBOL V5.2 who specify   *
    *                 the OPT(0) or OPT(1) compiler option when    *
    *                 compiling a COBOL program with a large       *
    *                 table defined with the VALUE clause or       *
    *                 initialized using an INITIALIZE statement.   *
    *                                                              *
    ****************************************************************
    * PROBLEM DESCRIPTION: The COBOL program may exhibit           *
    *                      slow performance due to sub-optimal     *
    *                      code that is generated for table        *
    *                      initialization.                         *
    *                                                              *
    ****************************************************************
    * RECOMMENDATION: Apply provided service.                      *
    *                                                              *
    ****************************************************************
    The compiler fails to generate optimal code for initializing
    tables when the optimization level is less than OPT(2).  For
    COBOL programs with very large tables, this can have a
    negative impact on the performance of the program.
    

Problem conclusion

  • The compiler was modified to generate optimal table
    initialization code at OPT(0) and OPT(1).
