UNDEFINEDTYPE

Message        The compiler was expecting a "<token>", but one was
               not found.  This condition could have occured because
               "<id>" is used in what might be a type cast, but
               there is no declared type of that name visible.

Description    The compiler has discoverd a syntax error.  This
               error may have been caused because a cast operator
               used an unknown type.

User Action    Correct the syntax error.
