Way to speed up append strings?

[Geoff Canyon]

This code runs in 5 ticks on my computer:

on mouseUp
   put ticks() into t
   put empty into tTest
   repeat 64000
     put "t" after tTest
   end repeat
   put ticks() - t
end mouseUp

Since that's appending a single character 64,000 times, I assume it's a 
worst-case scenario. Can you post the actual code you're using, and 
what performance you're seeing?
