    The SYS${foo} bits are logicals and you can show them by (I think)
invoking "SHOW LOGICAL *"; they should wind up referring to your boot
drive (e.g. DKA0:) and a top-level directory thereupon.  Descending
into subdirectories is done using periods, so to get to the "BAR"
directory in DKA0:[FOO] do a "SET DEFAULT DKA0:[FOO.BAR]".  I don't
recall off the top of my head how deeply they can nest as it's been
years (decades, actually) since I've been a VAXherder.

    The "HELP" command is always your friend.  You probably don't have
a "grey" or "orange wall" (the moniker applied to the very voluminous
VMS doco) but hints are likely available via the Google oracle.

    VMS is actually a very nice environment once one gets used to it.
It's very verbose compared to UNIX (and assorted UNIX-like systems)
but that's not necessarily a bad thing.

    What I want to find is a DG 32-bitter that I can run AOS/VS on
and not break the bank on electricity bills (or burn the house down).
