The AND relationship is used when more than three record identification codes identify a record.
To use the AND relationship, enter at least one record identification code on the first line and enter the remaining record identification codes on the following lines with AND coded in positions 16 through 18 for each additional line used. Positions 7 through 15, 19 through 20, and 46 through 80 of each line with AND in positions 16 through 18 must be blank. Sequence, and record-identifying-indicator entries are made in the first line of the group and cannot be specified in the additional lines.
An unlimited number of AND/OR lines can be used on the input specifications.
