How do I scan all the objects on a card?

Monte - thanks for your interest, but I have had no luck so far. I
don't see why the 'X=1...' formulation should work better than
'repeat for each...', but if it does, I guess it does. I chose
'repeat for each' because the Transcript dictionary warns that this
is a slower method, and I had no real reason to need the index 'i'.
Your solution implies that the controls on the card have unique
consecutive numbers starting from 1, which I didn't realise was the
case, and seems to be contradicted by the Transcript Dictionary which
says "The expression control 2 refers to the control whose layer is
2" which implies that the numbers are not unique, since not every
object is on a different layer. Also, I tried an experimental button
with this script:
on mouseUp
repeat with X=1 to the number of controls of this cd
put (the name of control i of this cd) into line i of fld "MyList"
end repeat
end mouseUp
But this produced a runtime error. I suspect that "control i" in this
context does not translate to stuff like "graphic i" or "image i" or
"field i" according to circumstances, a usage I have so far found I
have to organise myself. I tried a number of variations, but no luck
so far.
As to the GM, I've read many messages suggesting there are bugs in
the 1.1.1 Geometry Manager; and also some of the things I want to do
don't relate directly to geometry (for example certain properties
will have to be reset from arrays of values that relate to screen
size in complex ways; some clusters of objects stay together but move
to new bits of the screen; some background colours may change, etc.),
and I therefore need a scanning structure outside the GM to change
this other stuff, so might as well do the whole job there (I
thought). But I will look at the GM again.

Erik, thanks but I don't see how this helps me at run time (in fact
startUp time) within my app, but maybe I misunderstood your point.
Back to the cyber-drawing board. But I still do believe that Revo
itself knows how to do this.
