Appropriate syntax for referencing objects in a looping structure?

[Ops]

Christopher,

The name of your graphic pointer is:   pointer1      It's NOT "pointer1" 
(with the double quotes).  In your lone set statement, the quotes merely 
tell the engine that what's enclosed (withing the quotes) should be 
treated (or looked upon) as a literal string and NOT a 
variable/container...so in effect, your lone set statement actually 
conveys to the engine the literal string:  pointer1

In your repeat loop, you are telling the engine to look for a container 
named "pointer1" instead of pointer1, and it does not find it, and thus 
generates the error.  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.
