Working-Storage Section

The Working-Storage Section describes data records that are not part of external data files but are developed and processed internally by the program. Type-names may be defined in the WORKING-STORAGE SECTION.
record-description-entry
See File Section for a description. Data entries in the Working-Storage Section that bear a definite hierarchic relationship to one another must be grouped into records structured by level number.
data-item-description-entry
Independent items in the Working-Storage Section that bear no hierarchic relationship to one another need not be grouped into records, provided that they do not need to be further subdivided. Each is defined in a separate data-item description entry that begins with either the level number 77 or 01. For the format and the clauses required in a data-item description entry, see Data Division—Data Description Entry.
The initial value of any data item in the Working-Storage Section, except an index data item, is specified by associating a VALUE clause with the item. The initial value of any index data item, or of any data item not associated with a VALUE clause, is undefined.
Note: A maximum of 16 711 568 bytes is permitted for group items (including tables).
