Re: Appropriate syntax for referencing objects in a looping structure?
Opie, Thanks for the reply. well, yes, you're right that this works - and I would have sworn I had tried it, but I guess the confusion stems from the fact that in my regular format I have to use the quotes. So I must have just been loading the variable wrong earlier when I was doing it before I looked up 'quote' ... :/ It seems weird to not put quotes when it is in a variable and to put them when it is not. The shorter way is the first thing I tried! I promise! must have been 4am typos or something. Thanks again!

Change your repeat to: repeat with i = 1 to 3 put "pointer" & i into tName answer tName -- should now give you the right content: pointer1 set the angle of graphic tName to rotAngle end repeat A shorter way to write the above would be: repeat with i = 1 to 3 set the angle of graphic "pointer" & i to rotAngle end repeat Hope this was clear.
