I am assuming that you are ignorant and not being sarcastic.
Compaq OpenVMS is dying, I admit. It is the operating system
for the former Digital Equipment Corporation computers, including
both DEC VAX computers and DEC Alpha computers. But, there are
quite a few of them still running and many are becoming home or
personal systems. TeX and LaTeX are available for them.
I do not see that International Business Machines Corporation
going out of business any time soon nor do I see that IBM would
be withdrawning its flagship operating system for its large
mainframe computers. These computers have an upward compatible
CISC architecture that dates its beginnings from the late 1950's
and which had single system installations with multiple gigabytes
of RAM and multiple terabytes of disk or disk-like storage in the
late 1970's (I know this because I worked on some). These computers
supported some form of interactive user environments since the
early 1970's including CICS, TSO and POSIX-X/OPEN environments
and frequently support several thousand users at the same time.
I seem to recall that TeX and LaTeX has been ported at least
once to such systems.
I feel that it would be appropriate not to preclude such systems
in the future. All that would be required would be to do a
record level translation at TeX's lips to trim trailing spaces
if the record format is fixed and append a line terminator and
feed that to TeX's mouth.
