$| ${oref IS $[NOT$] INSTANCE OF $}

What does it do?
A predicate expression uses the predicate operator IS to determine a truth value from the state of an operand.



Latest notes:

Apart from INSTANCE OF, no operands of the possible predicate expressions are general expression positions. No predicate expression can be applied to a calculation expression.
NON_V5_HINTS
The predicate expression IS $[NOT$] REQUESTED is obsolete and was replaced by IS $[NOT$] SUPPLIED.
