Error description

  • Programs compiled with Enterprise COBOL V6.4/V6.5, and ARCH(14),
    that contain a large number of MOVE statements converting data
    from USAGE DISPLAY fields to numeric edited fields have worse
    runtime performance than Enterprise COBOL V6.3. The compiler
    generated inefficient instructions when converting from a USAGE
    DISPLAY to a Numeric Edited, resulting in slower performance.

Problem summary

  • ****************************************************************
    * USERS AFFECTED: Users of Enterprise COBOL 6.4 compiling      *
    *                 programs at ARCH(14) and above that contain  *
    *                 a large number of MOVE statements converting *
    *                 data from USAGE DISPLAY fields to numeric    *

    * PROBLEM DESCRIPTION: Program may have worse runtime          *
    *                      performance than Enterprise COBOL 6.3   *
    ****************************************************************
    * RECOMMENDATION: Apply the provided PTF                       *
    ****************************************************************
    The compiler generated inefficient instructions when converting
    from a USAGE DISPLAY to a Numeric Edited, resulting in slower
    performance.
    

Problem conclusion

  • The compiler was updated to produce optimized instructions for
    above conversion when compiled with the NOINVDATA option.
