**Section - Adjusting origins and endpoints**

[This phrase is intended to allow origins of g-elements and g-windows to be changed simply. It can also be used to change the endpoint of a primitive g-element.]

To adjust the (P - a (list of numbers) valued property) of (O - an object) by (dX - a number) and (dY - a number):

let X be entry 1 of list property P of O;

let Y be entry 2 of list property P of O;

let X be X + dX;

let Y be Y + dY;

now entry 1 of list property P of O is X;

now entry 2 of list property P of O is Y.
