Arc (procedure)
Draws an arc in a counter-clockwise direction. If there is a current point set, the command draws a straight
line from the current point to the start point of the arc. Whether or not a current point is set when the
command executes, after execution the current point is the end point of the arc.
You define the arc you want to draw by specifying the x and y coordinates of the center of the circle, the
radius of the circle, and the start and end points for the arc. You specify each of the start and end points of
the arc as an angle; the command uses the angle to position the point. For example, to position the start
