    * PROBLEM DESCRIPTION: Index query access may return less rows *

    ****************************************************************
    Index query access may return less rows than actually qualify
    when index is defined UNIQUE, NOT PADDED and has at least one
    varying-length column.
    
    An error in the index selection expression comparison
    routine caused less rows to qualify. The routine failed to
    handle index keys with reserved space.
    Note: DSN1PRNT with FORMAT option will display key(s)
    with reserve space ("RESERVE SPACE").

Problem conclusion

  • Index selection expression comparison routine has been updated
    to correctly compare index keys defined on UNIQUE, NOT PADDED
    index.
