15.65.3.8  Example  - You have entered a 3 dim array with 20 by 20 points.
X ranges from 0 to 10, Y from 100 to 200.  The total array will not fit on
the terminal screen so you show a subset of the data:
     TD:SHOW DATA POINTS 3 to 8 LINES 5 to 10
     TD:SHOW DATA POINTS 1 5 LINES 1 5 (SHOWS 25 points)
     TD:SHOW DATA LINE=1 (Shows only first 20 points)
     TD:SHOW DATA LIMITED FROM .5,100 TO .8,120

                                  Example
You  have  entered  100  data  points  X,Y,DX,DY etc.  To show only points
number 5 to 20
     TD:SHOW DATA POINTS 5 to 20
