Moving an object in Quark 4.11

How do you move a selected object in Quark 4.11 using Applescript?
I want to move it to position X=0, Y=0 -I just can’t figure out how to do that, when looking in the Quark dictionary.

try this :

set origin of bounds of selection to {“0”, “0”}

works with XP 4.0, dont know with XP 4.11
