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.
