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 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.
