undisplay I<display-number> ...
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. C<delete
display> has the same effect as this command. Use C<info display> to
see current list of display numbers.
