   I have about 10 years of experiance with VMS. I used to have a small
VAXcluster here prior to switching my machines to Ultrix (and then later
dumping the VAXes for PC's/386BSD).

   Early versions of VMS had a simple {process, job, group, system} hierarchy.
Later versions of VMS created a much more generic system that allowed for
the creation of arbitrary logical name tables that allowed for custimized
access/use. The old hierarchy was preserved using the new mechanism, however.
Logical name tables have access permissions (system, owner, group, world)
and individual entries have various flags which affect how the logical name
is translated.
