Special level-numbers identify items that do not structure a record. The
special level-numbers are:
- 66
- Identifies items that must contain only a RENAMES clause; such items
regroup previously defined data items. (For details, see RENAMES Clause.)
- 77
- Identifies data item description entries — independent
Working-Storage, Local-Storage or Linkage Section items that 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. The condition-name entry must contain only a VALUE clause. (For details,
see VALUE Clause.)
Note: Level-77 and level-01 entries in the Working-Storage,
Local-Storage and Linkage Sections that are referenced in the program must
be given unique data-names, because neither can be qualified. Subordinate
data-names that are referenced in the program must be either uniquely defined,
or made unique through qualification. Unreferenced data-names need not be
uniquely defined.
