The closest I can find to a direct admission is a side comment in this Wired interview from the mid-1990s: http://www.wired.com/wired/archive/2.08/allen_pr.html Perhaps someone else will have more time/luck with Google than the couple of searches I tried. Plenty of third party assertions but I didn't see anything to back it up. Let us say, "not many average Mac users." Though limiting it to "average XYZ users" leaves the named group open to accusations of all manner of ignorance and stupidity... ;^) But I imagine anybody who ever looked at developing software for the Mac very quickly discovered this when they learned that - uhm, was it ADPA? The earlyish development environment for the Mac - included a shell, and you could see the filesystem more directly. So, what else have we got out there for file/directory path separators? We've got DEC's "DEVICE:[DIR.SUB]FILE.TXT;1" and uhm... actually, I can't think of the conventions for any others at the moment. Can anybody think of any interesting ones? I can't remember what DomainOS did, but I remember it striking me when I learned of it. Mainframes? RTOSes? --S.
