ERRWZTIMEOUT, Error while processing $ZTIMEOUT
Run Time Error: This indicates a problem invoking the current $ZTIMEOUT vector and usually accompanies other error messages
Action: Examine and correct the code vector specified by $ZTIMEOUT, or if there is none, examine the current value for $ETRAP or $ZTRAP. Unlike $ETRAP and code values for $ZTRAP, which are evaluated when they are assigned, compilation of $ZTIMEOUT vectors occurs when the vector is invoked by the expiration of the specified time.
