SCALE
allows the scale factor used by the graphics procedures to be altered.
A
scale
of 'x' implies that a vertical line of length 'x' will fill the vertical axis of the Window in which
the figure is drawn.
A
scale of 100 is the default
SCALE
also allows the origin of the
coordinate system to be specified. This effectively allows the window being used for the
graphics to be moved around a much larger graphics space.
