Condition-name

Each condition-name must be unique, or be made unique through qualification and/or indexing, or subscripting. If qualification is used to make a condition-name unique, the associated conditional variable can be used as the first qualifier. The hierarchy of names associated with the conditional variable or the conditional variable itself must be used to make the condition-name unique.

If references to a conditional variable require indexing or subscripting, references to any of its condition-names require the same combination of indexing or subscripting.

The format and restrictions on the combined use of qualification, subscripting, and indexing of condition-names are exactly those of "identifier" except that data-name-1 is replaced by condition-name-1.

In the general formats, "condition-name" refers to a condition-name qualified, indexed or subscripted, as necessary.
