OK, OK, I'll bite on some of the replies I've received.
1) There are a large number of fanatics out there who foam at the mouth when
ever someone bad mouths Unix. Tough life. I have no sympathy for such.
2) I was wrong about VMS src, I guess they do release it - on microfiche unless
you want to pay mega$$ for machine readable. Sorry.
3) In regards to Unix robustness - I'll make you all a challenge: I'll bet I can
take a commercially available Unix (BSD based, I don't play w/ AT&T & they
don't play w/ me) and find twice as many ways to screw it up as you could
in VMS. This means anything from kernel bugs to application bugs.
The point is that Unix systems are hacked together things which work most
of the time; you learn real fast which buttons not push. In VMS they took
those buttons away. It's a much more solid product.
4) Crashing: You bet it crashes. Until you fix the bugs. Even the people who
denied this said that if you added this or pushed that or diddled the other
thing it would crash. Like I said, it crashes all the time. Look at the
list of bugs *known* about BSD Unix. Look at tektronix, they claimed to
have a port of 4.2 with over **2000** bug fixes. 2,000??? In a distribution
version of Unix? Come on. At CS here it took them 6 months to a year to
get 4.2 to the point that it didn't crash each time the load got to 20 on a
780 (I know, I used that vax during the "fixing" period).
