Re: what's wrong with this loop syntax?

["Michael Newberry" <mnewberry@...>]

Luiz, OK, thanks. Is there any way to make it more compact (and more 
readable to me, at least), where the loop is tested at the top of the loop? 
Here is what I use:

   while true do
       str = S:Next()
       if str == nil then break end
       -- [code]
   end
