I'm guessing you're already aware of what Malcolm suggested
in preceding followup, and it's not adequate. And since I've
read your posts in comp.os.vms, I'm also guessing we're
talking about an ods-2/5 filesystem at one end, and maybe a
linux ext3, or whatever, at the other. Could you elaborate on
that a little? And does linux have some ods-2/5 support so you
can mount a vms disk? I wasn't aware of that. If you can indeed
just mount it, then by all means try Malcolm's suggestion and
see what happens. Should just work if the ods filesystem support
is any good. Otherwise, how are you intending to even access
the disk? Decnet for linux (note that it's no longer being
very actively supported)? I think that would be the driving
question that dictates an appropriate answer to your question.
So you need to supply all that additional info first.
   By the way, I usually just ftp zipped files back and forth
between vms and linux boxes on my soho lan. Despite your
"out of control" issue, I'd just write a script (using C's
system() if you want the script in C) to do the job, unless
security's some really, really significant issue for your
situation.
