Instance :: operator logical - Type conversion

The operator converts the instance handle into a logical ( boolean ) value. The value is true ( YES ) when the handle has an instance area pointer and false ( NO ) when the instance area pointer is false. This operator allows using instance handles in logical operations.

Return value: Syntactically, no value returned ( )

The NOTYPE variable results in an empty value.
