77-Level Description Entry COBOL

In the Working-Storage and Linkage Sections, a special level-number of 77 can be used in data description entries that are not subdivisions of other items, and are not themselves subdivided. These data description entries specify noncontiguous data items. Such a data description entry is elementary.

A 77-level data description entry must contain a data-name and either the PICTURE clause or the USAGE IS INDEX clause, but can contain an OCCURS clause only in the Working-Storage Section. Other clauses are optional and can be used to complete the description of the item if necessary.
