Possible program line
G2D1X200Y300I250J275
Where G2 = Drafting Command
D1 = Pen Command (down)
X200 = X Portion of (X,Y)
Y300=Y Portion of (X,Y)
1250 = Distance of Center
J275 = Distance of Center

Point Coordinate (for Lines)
Point of Circle Along X-Axis (X-Coordinate)
Point of Circle Along Y-Axis (Y-Coordinate)

(3) Third line should set common scale factors for both axes.
(4) Next 1 ines should preset zero reference point, preferably in left-hand
corner of drawing.
(5) Rest of lines are program lines and should be written, whenever possible,
so that entire figure is drawn in one (or as few as possible) continuous motion,
beginning in lower left portion of figure.
(6) Do not forget to insert pen commands.
When used, they should be typed
immediately after drafting command.
(7) All programs must end with program stop command (MOO).
(8) Each program 1 ine typed (on teletype or console) must end
return and line feed.
