Every entry must have a subject; that is, a name assigned to the item. This
data name is used to reference the item from the Procedure Division.
It
must not be qualified or subscripted when used as the subject of a Data
Division entry.
The word FILLER may be used instead of a data name as the subject of an
entry that is never referenced.
It
may name only an unused elementary item
within a record. A record containing a FILLER item can be referenced from
the Procedure Division, although the FILLER item itself cannot. A FILLER
item must have a level number and any data description clauses that would be
required for a data-name entry in the same location.
Report names, file names, library names, and condition names are special
cases of the data name used in report, description, file description, source
library, and condition name entries. Appendix B contains the rules for
forming all data-names.
The initial value of any item in the Working Storage Section is specified with
the VALUE clause in the record description entry.
A literal is an explicit statement of the value to be used in an operation per-
formed by the object program. Literals may be used wherever the format
indicates. Appendix B contains a description of literals and the rules
governing their formation.
Figurative constants are predefined as part of the COBOL language. They
may be used wherever a literal is allowed in the reference format. A
complete list of figurative constants is contained in Appendix B.
