We used to have one back in the old days. It had to be installed

there was one small bit of odd behavior relating to VMS privs that
was non-intuitive, but for 99.997% of what we did, you *became* that

Very dangerous stuff. VMS will crash if you do the wrong thing when
in Kernal Mode. We had a couple of utilities that had to be rebuilt
when we updated VMS - one that did an "su" and one that worked like
"w" (telling you all about the other login processes, including what
command they were running and some other stuff that SHOW PROCESS didn't
show you).
These were written in the VMS 3.6ish days and brought along to VMS 4.x.
I could dig them out, but I doubt they were ever ported to VMS 5.x,
let alone anything "modern".

As an aside to the current VMS discussion, does
anyone know
of an equivalent to the Unix "su -" command for VMS?
3) I suspect that someone will have created a SU program as well - this
isn't too hard to write (not that I'm volunteering).
