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.

•Moves the cursor to the specified coordinates after raising the pen.

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

•When scaling is on, user coordinates are used.

•Also, when scaling has been performed, the values for X and Y are real numbers.

•When scaling is off graphics units are used.

•When there is no scaling, the coordinates values for X and Y are integer numbers.

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 set as default.

•Moves the cursor to the specified coordinates after lowering the pen. (This plots a straight line.)

•Using this instruction without a parameter lowers the pen without changing the cursor position. ( One dot is plotted.)

•When scaling has been performed, the cursor is moved by user coordinates.

•Also, when scaling has been performed, the values for X and Y are real numbers.

•When there is no scaling, the cursor is moved by absolute coordinates in graphics units.

•When there is no scaling, the coordinate values for X and Y are integer numbers.

X ; X coordinate of the cursor movement destination

Y ; Y coordinate of the cursor movement destination

•X and Y are absolute values in user units or graphics units.

•Moves the cursor to the specified coordinates.

•Plots a straight line only when the pen is down.

•When scaling has been performed, the values for X and Y are integer numbers.

•When there is no scaling, the cursor is moved by absolute coordinates in graphics units.

•When there is no scaling, the coordinate values for X and Y are integer numbers.
