Special level-numbers
Special level-numbers identify items that do not structure a record. The special
level-numbers are:
- 66
- Identifies items that must contain a RENAMES clause; such items regroup
previously defined data items. (For details, see RENAMES clause.)
- 77
- Identifies data item description entries that are independent
working-storage, local-storage, or linkage section items; they are not
subdivisions of other items and are not subdivided themselves. Level-77
items must begin in Area A.
- 88
- Identifies any condition-name entry that is associated with a particular
value of a conditional variable. (For details, see VALUE clause.)
Level-77 and level-01
entries in the working-storage, local-storage, and linkage sections that are
referenced in a program or method must be given unique data-names because
level-77 and level-01 entries cannot be qualified. Subordinate data-names that
are referenced in the program or method must be either uniquely defined, or made
unique through qualification. Unreferenced data-names need not be uniquely
defined.
