        undisp[lay][ nnn]

        Cancel some expressions to be displayed when program stops. Arguments
        are the code numbers of the expressions to stop displaying. No argument
        means cancel all automatic-display expressions. "delete display" has the
        same effect as this command. Do "info display" to see the current list
        of code numbers.
