JS CS3 How to make guides

Question

I just gave a try to creating guides in CS3 with this sophisticated snippet:
var lyr = app.activeDocument.layers.add();
var gd = lyr.pathItems.add()
gd.setEntirePath(Array(Array(100,0), Array(100,100)));
gd.guides = true;
and was hit by two surprises:
1. I expected the guide to spread across the entire doc. I thought that despite the coordinates, the engine would extend the line by default, since by mousing in UI, I never managed to make a guide covering only a portion of a doc.
2. Upon creation, the guide was selectable and moveable, showing the anchor points, basically it appeared as any other line, only with strokeColor appropriate for guides. (After a few clicks it kind of morphed into a real guide)
So my guess is that I'm doing something wrong here... Any ideas?

Hi Kasyan,
Ole is probably right that the way to go would be a platform-specific
script.
You can do it using an idle event without it being too much of a
resource drain. You can do something like this (in CS3 using a
persistent engine):
if(yourUniqueNameIdleCounter == undefined){yourUniqueNameIdleCounter=0}
yourUniqueNameIdleCounter++;
if(yourUniqueNameIdleCounter>60){
yourUniqueNameIdleCounter=0;
do your check();
This would increment the number every second or so. Every time the
number hits 60 (about a minute -- give or take, depending on a lot of
factors) your check will be run. For every other idle event, the only
thing done would be incrementing the variable...
