- Could someone tell me how "open" Open VMS really is. Is it so open
- that someone can obtain the source codes, or is it another proprietary
- operating system with the word "Open" attached to it? Thanks.
-
- This is bound to start a whole bunch of flame wars, as it does when the issue
- of "openness" comes up in any newsgroup or mailing list.
-
- "Openness" is the latest bit of market-speak, replacing such phrases as "user-
- friendly" and competing with "object-oriented". The term was, if not invented
- by Sun, certainly heavily pushed by them as the centerpiece of their marketing
- strategy. If you believe that "Open" means "sources are available", I suggest
- you ask Sun about the availability of sources for SunOS or Solaris. Or ask
- ANY of your favorite commercial Unix vendors about the availability of sources
- for their offerings.
-
- FWIW, source LISTINGS of almost all of VMS are available on CD-ROM quite
- cheaply. (Some fairly small pieces that DEC considers proprietary are left
- out. Generally they are extremely hardware-specific.) Source KITS have
- traditionally been available, but hard to get and quite expensive; I don't
- know the current state of things. DEC has announced that they intend to
- make complete source kits available, along with licenses to port VMS to other
- architectures. I don't believe anyone has taken them up on it, so I doubt
- they've ever worked out all the details.
-
- There are several DEC-sponsored books that describe the inner workings of VMS.
- I know of no analogous documentation for any commercial version of Unix - and
- even the classic books (Leffler et al on 4.3BSD, Bach on System V) are much
- less complete, and of course by now well out of date, and in any case don't
- describe any particular implementation that you can buy.
