Condition-name Condition (Conditional Variable)
In a condition-name condition, a conditional variable is tested to determine whether or not its value is equal to one of the values associated with a condition-name.
Condition-names with DBCS and internal floating-point items are allowed.
Condition-names with external floating-point items are allowed.
If the condition-name is associated with a value or range of values, then the conditional variable is tested to determine whether or not its value falls in this range, including the end values.
The rules for comparing a conditional variable with a condition-name value are the same as those specified for relation conditions.
The result of the test is true if one of the values corresponding to the condition-name equals the value of its associated conditional variable.
