Delete item won't work in Repeat for each loop

[Mark Schonewille]

Hi Ian,

When you delete items, the number of items gets smaller while the  
variable that counts the items goes up. At some point, you're trying  
to delete items that don't exist. Use "down to" to avoid this:

repeat with x = number of lines of myList down to 1
   delete line x of myList
end repeat

(in this simple example, you can also use "delete last item", obviously)

Best,

Mark
