Function GraPos() Foundation
Determines pen position or moves pen.
GraPos( [<oPS>], [ <aPoint> ] ) --> aPenPosition
The return value of GraPos() is an array of two elements which contains the coordinates for the pen position before the call of GraPos() (as <aPoint>).
Each presentation space is provided with a pen for the output of graphic functions. When lines are drawn, the pen position changes. That is analogous to a change of position of the screen cursor when characters are output on the screen in text mode. GraPos() determines the current pen position or repositions the pen. The current pen position is used by most graphic primitives when an optional start coordinate is not specified.
