VMSclusters (the name was changed 10 years ago) can interconnect
via fiber.

The Open in OpenVMS means that it has all the standard Posix &
X Window API calls.

There's no such thing as OpenVAX, since VAX is a hardware archi-
tecture.

BTW, VMS has already booted on Itanium, and when it ships early
next year, you'll be able to have tri-arch VMSclusters:
VAX/VMS, Alpha/VMS & Itaniac/VMS all accessing & sharing the
same files simultaneously.

Some former UNSCOM officials are alarmed, however. Terry Taylor,
