   There is no difference between the languages here. The flush should be   
   there, but because it is probably empty for the screen in TP, omitting   
   doesn't happen to hurt.   
      
   But the TP textfile definition does include a flush function, and textfile   
   types are pluggable (by e.g. assigncrt), so an alternative implementation   
   that sends it to a LCD over a one wire connection might require it.
