Problem summary

  • ****************************************************************
    * USERS AFFECTED: Users of Enterprise COBOL 6.5 compiling      *
    *                 programs with ARCH(11) that have loops       *
    *                 copying data from one alphanumeric or        *
    *                 alphabetic data item to another, one byte at *
    *                 a time, stopping either when the end of the  *
    *                 sender or receiver is reached, whichever is  *
    *                 shorter, or when a terminating character is  *
    *                 found in the sender, and where the loop      *
    *                 index is of type USAGE DISPLAY.              *

    ****************************************************************
    * RECOMMENDATION: Apply the provided PTF                       *
    ****************************************************************
    The optimizer can generate an efficient instruction sequence
    when copying data between alphabetic or alphanumeric data items,
    stopping when the end of the shorter data item is reached or
    when a terminating character is found in the sender. The
    optimizer did not allow a USAGE DISPLAY data item as a loop
    counter in this sequence, but rather than avoiding the sequence,
    the optimizer attempted to generate the sequence and then
    terminated when the unexpected USAGE DISPLAY data item was
    found.
    

Problem conclusion

  • The compiler has been fixed to allow USAGE DISPLAY loop counters
    when optimizing the copying of data between alphabetic or
    alphanumeric data items.
