oflush --Command, no inputs.
     Normally, when you tell Logo to print something, the printing is not
     done right away. Instead, Logo remembers everything you tell it to
     print, and the printing is done all at once the next time Logo is
     waiting for you to type something. This arrangement makes Logo much
     faster than it would be if everything were printed immediately. The
     oflush command tells Logo to print whatever you've previously asked
     for right away, without waiting.
