In a comparison between a signed zoned decimal item and an alphanumeric character field, this option specifies whether to ignore the sign part of the zoned decimal item (ZWB) or not (NOZWB). Here, an alphanumeric character means an alphanumeric data item, alphabetic item, alphanumeric edited data item, numeric edited data item, nonnumeric literal, or figurative constant other than ZERO.
