The OR relationship is used when two or more record types have common fields.
To use the OR relationship, enter OR in positions 16 and 17. Positions 7 through 15, 18 through 20, and 46 through 80 must be blank. A record identifying indicator can be entered in positions 21 and 22. If the indicator entry is made and the record identification codes on the OR line are satisfied, the indicator specified in positions 21 and 22 on that line is set on. If no indicator entry is made, the indicator on the preceding line is set on.
An unlimited number of AND/OR lines can be used on the input specifications.
