How do I scan all the objects on a card?

[Sarah]

Hi Graham,

I think what is confusing you about control numbers is that they are 
not static, but they are unique. They represent the ordering of the 
controls on the card, so they have to be unique as no two controls can 
be at the same position in the layering list. However these numbers 
change if you alter the layer of any control, so control 4 might refer 
to different objects at different times. This still provides a 
perfectly valid way to refer to all your objects in a single loop.

While "repeat for each" is a much faster method of looping than "repeat 
with", I think the difference is only significant when you have a large 
number of repeats. I don't imagine that the number of controls on a 
card can be up in the thousands where using "repeat with" might be a 
problem.

I am one of those who have found that scripting my own geometry 
settings in a resizeStack handler is much the most reliable way to go. 
I am hoping that the GM will be improved in Rev 2, but scripting your 
own is not that hard and works well.

Cheers,
Sarah
