Position 19 (Number)

Entry : Explanation

Blank : The program does not check record types for a special sequence (positions 17 and 18 have alphabetic entries).

1 : Only one record of this type can be present in the sequenced group.

N : One or more records of this type can be present in the sequenced group.

This entry must be used when a numeric entry is made in positions 17 and 18. If an alphabetic entry is made in positions 17 and 18, this entry must be blank.
