Good trick! I didn't know you could do that either. 

I wondered if the function was called just once, or on every repeat. Your exapmle wouldn't tell, because the function would return the same stuff every time.

So I tested it. The answer is that the function is called only once. Good!

global gCount

on mouseUp
   global gCount
   put 0 into gCount
   repeat for each line L in mylines()
      put L & cr after msg
   end repeat
   put gCount after msg -- how many times mulines() was called
end mouseUp"

function mylines
   global gCount
   add 1 to gCount
   return "1" & cr & "2" & cr & "3" & cr
end mylines
