GR

Graphic Rectangle draws a rectangle in the graphic plane n1.

 GR [n1,n2,n3,n4,n5]

 n1:      Graphic plane to draw rectangle on  <last graphic>
 n2,n3:   Upper left corner point             <cursor position>
 n4,n5:   Lower right corner point            <cursor position>

If n1 < 0, the rectangle outline is cleared rather than drawn. If all of (n2,n3,n4,n5) are zero or null, DCP will prompt the user to move the cursor to the corner points.
