SYS$NET, WRT DECnet, has special meaning and a special definition when
it's define by a DECnet network connection.  Take a careful look as what
you get when you use TCP/IP. ;)

Yup.  Quite simple.  Map DCL.EXE/DCLTABLE.EXE, then callback to DCL with
the file specification of the user's LOGIN.COM.  All symbols and logicals
will be defined in the NETWORK process according to what the user has in
their LOGIN.COM.  Assumes the user has F$mode().EQS."NETWORK" conditional
coding correctly established in the LOGIN.COM.

Yes. ;)
