Its possible. How easy depends on where you are printing. Using curses in a character based terminal its easy, just define the window within the screen that you want to change. Similarly any GUI toolkit will likewise be easy. But if you are uising a teletype interface you are reduced to using backspace characters and it gets messy, even with a cursor addressable screen (such as a 3270 or ANSI terminal) it still gets very hard to keep track of exactly what to erase and when. > For example, if I'm making a little noughts and crosses > game and I print the board: I'd use curses for this.
