MONITOR

ON_or_OFF

 Using the MONITOR command with the keyword OFF is a means of disabling
 graphics output to the graphics terminal monitor.  This can be useful
 when executing command files, via the EXECUTE command, which the user
 is confident of and does not need to monitor.  The hardcopy graphical
 output is not affected, and is much quicker to obtain. To make the
 previous monitor type again available, enter the MONITOR ON command,
 and the terminal_type that was last in use will again be available for
 monitoring graphics.
