Using Identifiers

An identifier is a data name made unique by qualifiers, subscripts, or qualifiers and

subscripts. A data name being used as a subscript or qualifier cannot itself be

subscripted.

Identifier syntax is:

The following examples illustrate specification of identifiers:

unique-identifier

item-1 OF group-a

element OF name-table OF master-data (master-num)

Using Condition-Names

Items are tested frequently by a program. Assigning a condition-name to an item is a

convenient way to refer to the item and determine its value.

Every condition-name must be unique or capable of being made unique through

qualification and/or subscripting. If qualification is used to make a condition-name

unique, the conditional variable can be used as the first qualifier. The containing data

names of the conditional variable can also be used as qualifiers. If references to a

conditional variable require subscripting, then any of its condition-names must have the

same subscripting.

The following example illustrates a condition-name called restricted-use:

01 inventory.

02 part-number OCCURS 100 TIMES ...

03 prefix PIC 99.

03 use-code PIC 9.

88 restricted-use VALUE 1.

03 supplier-suffix PIC 99.

The condition-name, restricted-use, might be referenced as:

IF restricted-use OF use-code IN part-number (30)
