HP 5961-0509 manual Example Using Arc Relative to Draw Arcs, 20-14The Vector Group

zSweep Angle — Specifies (in degrees) the angle through which the arc is drawn. A positive angle draws an angle in the positive direction (angle of rotation); a negative angle draws the angle in the negative direction.

zChord Angle — Specifies the chord angle used to draw the arc. The default is a chord angle of 5 degrees. Refer to the Arc Absolute (AA) command discussion (earlier this chapter) for information on setting and determining the chord angle.

Table 20-8 Example: Using Arc Relative to Draw Arcs

ECE	Reset the printer.
EC%ØB	Enter HP-GL/2 mode.
IN;	Initialize HP-GL/2 mode.
SP1;	Select pen number 1. Even though there is no
	physical pen, the SP command must be used
	to enable printing.
PA1500,1500;PD;	Specify the starting position as (1500,1500)
	and put the pen down.
AR0,2000,80,25;	Draw an arc with a center point 0 plu in the X
	direction and 2000 plu in the Y direction from
	(1500,1500). Specify the arc section to be 80°
	(positive angle), with a chord angle of 25°
AR2000,0,80;	Draw an arc with a center point 2000 plu in the
	X direction and 0 plu in the Y direction from the
	current pen position. Specify the arc section to
	be 80° (positive angle), with a default chord
	angle (5°).
EC%ØA	Enter the PCL mode.
ECE	Send a reset to end the job and eject the page.
