Drawing commands

The Drawing commands act on the display. The scale of the

display depends on the current aplet’s Xmin, Xmax, Ymin,

and Ymax values. The following examples assume the HP

39G/40G 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, and

end_angle_measurement.

ARC x;y;radius;start_angle_measurment;

end_angle_measurment:

Example

ARC0;0;2;0;360:

FREEZE:

Draws a circle centered

at (0,0) of radius 2. The

FREEZE command

causes the circle to

remain displayed on the screen until you press a key.

BOX Draws a box with opposite corners (x1,y1) and (x2,y2).

BOX x1;y1;x2;y2:

Example

BOX -1;-1;1;1:

corner at (–1,–1), upper

corner at (1,1)
