    AFAIK File I/O is impossible in Javascript/VBScript. The script runs on the client-side so if you *could* write files you would be writing to their machine not the server.
    You'll need to use a server-side language like Perl or PHP for this.

    impossible fullstop? even on ASP pages where the client cant access it and everything goes on server side?

    AFAIR, we were told that one of the great benefits of Javascript is that is it not allowed to read/write from the client computer, therefore is not usable for hacking. I think it is allowed read/write to the server computer though, for authentication purposes blah blah blah.....maybe someone an confirm? :)

    Confirmed. Tainting (don't even ask) will allow you do do more with JavaScript, but nothing with I/O. VBS can access the FSO on the client (hence all those fun VBS macro viruses for word and outlook), but this would be disabled on the vast majority of browsers.

    From your requirements, I'd hazard a guess that your best option would be to send your text based data from the server with a content-type of unknown. That way the broser will attempt to download the file rather than display it.

    Only problem is that it won't have a .txt extension unless you actually start doing silly things on the server like associating .txt with the scripting language you're using.

    An alternitive would be using client side ActiveX or just intructing the user to Save As...
