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.
