By 03/06/90, you may connect to a beta Twilight Zone at XXX-
XXX-XXXX. You may also reach me voice at 214-660-6054. Limit
the calls to an EXTREME minimum!
If I get multiple requests about a topic (as I did with VAX),
I will put something online the WHAT'S HACKING? subboards and the
beta system Twilight Zone ]I[.

VAX: The VAX acronym is derived from Virtual Address eXtension.
The VAX computer is designed to use memory addresses beyond
the hardware's actual limits, enabling it to handle pro-
grams that are too large to fit into physical memory. The
VAX computer system is a member of the Digital Equipment
Corporation (DEC) computer family. Currently the VAX
series includes models spanning the desktop VAX station to
mainframe class multi-CPU VAX processors. These vary from
the superminis, like MicroVAX, to the older, moderate sized
11/7XX series, to the newer 6000 series. These computer
systems commonly use an operating system known as VMS.
VMS: The VMS acronym is for Virtual Memory System. The operands
of VMS are very similar to other operating systems. Back
in the days of stand-alone computer systems, DEC had the
idea for streamlining the operation of their computers for
business and engineering. It conceived VMS as a way of
allowing the basic computer management to be done by a user
familiar with any of the multiple systems it made.
DCL: The DCL acronym is for Digital Command Language. It is the
fundamental language of the VMS. Those of you who have an
IBM system, you can think of a DCL program like a batch
file. You can do a lot with it (much more than a PC-DOS or
MS-DOS batch) but it work basically the same way. One
difference is that when you want to execute anything as if
you were typing it in at the command prompt, you first must
put a "$" in front of the command in the DCL program. DCL
programs are commonly called COM files as well. When you
are not executing a COM or DCL program file, you are almost
always typing things into the DCL processor.
