 Message        <Context> an incorrect number of arguments were
                passed to the builtin function, "<function
                expression>".

 Description    This message is output on OpenVMS systems when the
                number of arguments passed to the builtin function is
                not one.

 User Action    Correct the call to the builtin function.
