■ STEP Specifies that coordinates are relative to the current
graphics cursor position.
■ (x!,y!) The coordinates for the center of the circle or ellipse.
■ radius! The radius of the circle or ellipse in the units of the
current coordinate system, determined by the most recent
SCREEN, VIEW, and WINDOW statements.
■ color% A color attribute that sets the circle's color. The
available color attributes depend on your graphics adapter
and the screen mode set by the most recent SCREEN statement.
■ start! The starting angle for the arc, in radians.
■ end! The ending angle for the arc, in radians.
■ aspect! The ratio of the length of the y axis to the length of the
x axis, used to draw ellipses.
■ To convert from degrees to radians, multiply degrees by (PI / 180).
