the display depends on the current aplet's Xmin, Xmax,

Ymin, and Ymax values. The following examples assume

the hp 39g+ default settings with the Function aplet as the

current aplet.

ARC Draws a circular arc, of given radians, whose centre is at

(x,y) The arc is drawn from start_angle_measurement,
