Syntax

Effect
A predicate expression uses the predicate operator IS to get a
logical value from the state of an operand.
Notes
- No operand of the potential predicate expressions is a general expression position. No predicate expression can be applied to a calculation expression.
- The predicate expression IS
[NOT] REQUESTED is obsolete and was replaced by
IS [NOT] SUPPLIED.
