The Data-name or FILLER Clause
A data-name specifies the name of the data being described. The word
FILLER can be used to specify an elementary item of the logical record that
cannot be referred to explicitly.
General Format

Syntax Rules
- The data-name or FILLER clause
, if
specified,
must be the first word following the level-number in a data
description entry.
General Rules
- The key word FILLER can be used to name an elementary item or
group in a record. Under no circumstances can a FILLER item be referred to
explicitly. However, a data item defined with the key word FILLER can be used
as a conditional variable because such use does not require explicit reference
to the FILLER item but only to the value contained therein.
If this clause is omitted, the
data item being described is treated as though FILLER had been specified.
