.I range
is used to select a range from a plot that is  currently displayed on
a MASSCOMP graphics terminal.  First, click  the left mouse
button while pointing to  any vertical  position above  the origin of
the graph (extreme left side).  Next,  do the  same thing  at the end
point (extreme right side).  This completes the set-up portion of the
process.   Next, select  the desired  starting point  by clicking the
left  button  again  while  pointing  to  the  starting point (again,
vertical position doesn't matter).   From  now on,  the current range
will be displayed  at the  top of  the screen  as the  mouse is moved
across the graph.  The starting point  may be  reselected by pressing
the right mouse button.  After the range is satisfactory, clicking on
the middle mouse button will save the selected range and exit.
