I wrote "Mac OS". That's not "Mac OSX". Ask Apple... :) And Mac OSX is quite arguably a Unix-type system. >> Maybe someone else can fill in some of the missing OSes.

Doesn't help the fact that the slash is mainly on Unix-type systems, and that there are or were quite a number of other systems out there that use other separator characters. >> (URLs probably use the slash because the internet protocols have been >> developed largely on Unix-type systems for use with Unix-type systems?) > > It wasn't designed specifically for Unix-type systems, but for universal > access. Right... the URI/URL syntax was formalized in the early 90ies, when Unix-type machines were dominant on the internet. There are also quite a number of concerns that governed the choice of separators and escape characters for URLs that the IBM, Microsoft and DEC/VMS people couldn't really foresee in the 70ies (for example, when DEC and IBM started to use the slash as command line switch character -- which later precluded its use as path separator). > My point also was that a lot of programming languages use the backslash > as escape character.

Maybe... have you been involved in the decision? Or do you know what the reasons were? Do you know whether it was even Microsoft's choice? (Remember, they wrote DOS for IBM. And there was nobody who had foreseen the PC explosion.) Did you know that most DOS versions accept the / as path separator? That DOS was written on Xenix (Posix) systems (using the slash as path separator)? That Microsoft was for a long time pretty much a pure Xenix shop? > The problem with the world is stupidity. Right... And most people are /really/ smart 30 years after the fact; "I would have known it better" is about as smart as it gets :) Gerhard -- http://mail.python.org/mailman/listinfo/python-list
