The problem is that it depends not just on the OS. MacOS X is Unix and that can support zillions of different terminal types each with their own control codes. These are mapped to a standard set in a database called (depending on your Unix version!) terminfo or termcap (cap=capability) and manipulated by a utility called tty. The difficulty is that not all terminals support all capabilities so you have to call stty to first find out if the capability exists, then use stty again to set it. - Altogether far too messy for most mortals. The more common route on Unix is to use the curses library which provides a windowing toolkit for a dumb terminal. The default window is the whole screeen and curses allows you to position the cursor at any point on screen, clear the screen(Or any rectangular section of it) and so on. Try man terminfo for the full story, and man curses if you want to go down that route. Programs like vi and top are written using curses. > considering not clearing the screen. What a hassle. As someone else said thats actually the right approach on a Unix box. Consider that some folks might be using an old paper teletype where the text just prints onto paper which scrolls off the top. What happens with my print '\n'*100 there? - they get a lot of white paper! Now on DOS MIcrosoft used a thing called the ANSI terminal which is a kind of virtual terminal standard that a lot of terminal manufacturers could support in addition to their own standards. It was pretty dumb but by adopting a standard QBASIC et al could implement screen controlls in assembler so they were both fast and reliable. But it only workled because the PC only supported that one standard. The joys of multi platform computing! :-) Alan G. _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
