Repeat with slow on iOS?

[William de Smet]

Hi there,

Is 'repeat with' slow on iOS?
I notice a 1 or 2 second delay time on my iPad after clicking the button.
On the desktop however everything is really fast.
I just do this in a button:
     repeat with x=1 to 100
      put "a"&x into tVeld
      enable fld tVeld
       put empty into fld tVeld
       set the backgroundcolor of fld tVeld to white
    end repeat

Is there maybe another (faster) way to do this on iOS?

groeten,
William
