7.3.Pen Control and Plot Instructions

Instruction	Function
PU	Pen Up
PD	Pen Down
PA	Plot Absolute
PR	Relative Coordinate Pen Move
AA	Absolute Arc Plot
AR	Relative Arc Plot
AT	Absolute Three Point Arc
RT	Relative Three Point Arc
PE	Polyline Encoded
CI	Circle
BR	Bezier Relative
BZ	Bezier Absolute

PU - Pen up

PU [ X,Y [,...]] [;]

X ; X coordinate of the cursor movement destination

Y ; Y coordinate of the cursor movement destination

•X and Y are either relative or absolute, depending on whether a PA or a PR was the last plot command executed. The absolute coordinates are set as default.

•You can specify as many coordinate pairs as you wish. The cursor moves to each point in turn without drawing.

• Using this instruction without a parameter field raises the pen without changing the cursor position.

•Coordinates are specified in the currently selected unit.

•In symbol mode PU draws the specified symbol at each point in the parameter list.

•In polygon mode the specified coordinate pairs are placed in the polygon buffer.

• If an odd number of coordinates are specified, the final (unpaired) coordinate is ignored.

PD - Pen down

PD [ X, Y [,...]] [;]

X ; X coordinate of the cursor movement destination

Y ; Y coordinate of the cursor movement destination

•X and Y are either relative or absolute, depending on whether a PA or a PR was the last plot command executed. The absolute coordinates are the default setting.

• You can specify as many coordinate pairs as you wish. The cursor moves to each point in turn, drawing lines on the page.

•Using this instruction without a parameter lowers the pen without changing the cursor position.

•Coordinates are specified in the currently selected unit.

•In symbol mode PD draws the specified symbol at each defined point on the x- and y-axis.

•In polygon mode the specified coordinate pairs are placed in the polygon buffer.

• If an odd number of coordinates are specified, the final (unpaired) coordinate is ignored.
