How do Unix and VMS compare?

[Doug Gwyn]

I think you got the bit about VMS emulators on UNIX wrong.
Clearly, if VMS has a larger software base (as you claim),
then there would be motivation for VMS-on-UNIX, but this is
the opposite of the argument you gave for there not being one.

VMS doesn't matter in the big picture; it runs only on not-
very-cost-competitive DEC VAX processors.  UNIX runs practically
everywhere.  If Fortran is your bag, certainly there are fast
Fortrans available on various vendors' UNIX systems.  Shop around.
