Much nicer. :-) Don't forget to clear the screen, though. That ties the whole program together. -- Neil Cerutti

Using curses for the interface makes a lot of sense because it is already supported by almost every Unix/POSIX platorm, so re-implementation is only required for those odd platforms (Windows) where it does not exist natively,; because well documented on the internet and in print; and because a huge number of people are already familiar with its API. If licensing permits, I don't think it would be too difficult difficult to embed something like pdcurses into the existing curses module to use as a backup for platforms where curses does not already exist. If not, there cannot be much difference to writing a terminal emulator that runs inside the windows console and there are a *huge* number of terminal emulators available for ansi/vt100 terminals. Add a termcap database mechanism and an embedded emulator can easily convert the excape codes into actions for the console.

Nice idea, only that it's even less portable and requires manual setup... ;^) Uli -- Sator Laser GmbH Geschäftsführer: Thorsten Föcking, Amtsgericht Hamburg HR B62 932

Once upon a time, there were indeed many different kinds of actual physical terminals. However, they are all extinct now. All that's left is software emulations. And the one emulation they all have in common is the DEC VT100. So just assume you're displaying on one of those: sys.stdout.write("\x1b[2J")
