The hacker community, mindful of its origins, quickly dubbed it TWENEX (a contraction of "twenty TENEX"), even though by this point very little of the original TENEX code remained (analogously to the differences between ATandT V6 Unix and BSD).
DEC people cringed when they heard "TWENEX", but the term caught on nevertheless (the written abbreviation "20x" was also used).
DEC attempted to convince TOPS-20 users to convert to VMS, but instead, by the late 1980s, most of the TOPS-20 hackers had migrated to Unix.
Beginning users of Twenex Emacs were told how to edit using a single buffer and reading one file after another into that buffer.
C-x C-f (find-file), which behaves nearly the same as in Twenex Emacs, is in GNU Emacs the canonical way for all users to visit files.
Twenex Emacs was designed at a time when most display terminals did not have the ability to scroll part of the screen, and using existing empty lines made redisplay faster.

G-d saw that this was losing, and G-d said "Let there be Twenex", and there was Twenex.
Twenex is bogus anyways...." And so it went, tempting Eve all day.
You are forever cast out of the garden and cannot use Twenex again!" Well, Adam being kinda stuck up like he was he said "I don't wanna use that again, anyways." And man has been losing ever since on machines with less than 36 bits.

At the same time, the commercialization of AI technology lured some of the AI Lab's best and brightest away to startups along the Route 128 strip in Massachusetts and out West in Silicon Valley.
Stanford became a major TWENEX site, at one point operating more than a dozen TOPS-20 systems; but by the mid-1980s most of the interesting software work was being done on the emerging BSDUnix standard.
In April 1983, the PDP-10-centered cultures that had nourished the File were dealt a death-blow by the cancellation of the Jupiter project at Digital Equipment Corporation.

BBN developed their own system, called TENEX (TEN EXecutive), and in creating TOPS-20 for the DEC-20 DEC copied TENEX and adapted it for the 20.
Usage: DEC people cringe when they hear TOPS-20 referred to as "Twenex", but the term seems to be catching on nevertheless.
Release 3 of TOPS-20 is sufficiently different from release 1 that some (not all) hackers have stopped calling it TWENEX, though the written abbreviation "20x" is still used.

Twenex system as yet another authoritarian symbol begging to be subverted.
Stallman, the hacker who coined the Twenex term, says he came up with the name as a way to avoid using the TOPS-20 name.
Not only did Twenex boast built-in security, but the system's software engineers had designed the tools and applications with the security system in mind.

EMACS is available for distribution for use on Tenex and Twenex systems (It does not run on Bottoms-10, and the conversion would not be easy).
To 11 EMACS Manual for TWENEX Users use these commands on such keyboards, you need to use ___ ______ two-character circumlocutions starting with a bit prefix character which turns on the Control or Meta bit in the second character.
Files are the objects which Twenex uses for storing data for communication between different programs or to hold onto for a length of time.
TWENEX was successful and very popular; in fact, there was a period in the early 1980s when it commanded as fervent a culture of partisans as Unix or ITS — but DEC's decision to scrap all the internal rivals to the
VAX architecture and its relatively stodgy VMS OS killed the DEC-20 and put a sad end to TWENEX's brief day in the sun.

-*-Outline-*- This file describes the differences between GNU Emacs 19, Twenex Emacs, Gosling Emacs (including the commercial versions by Unipress) and CCA Emacs.
Permission is granted to distribute modified versions of this document, or of portions of it, under the above conditions, provided also that they carry prominent notices stating who last changed them.
Updated March 1993 for Emacs 19 by Eric S. Raymond * How is this Emacs different from Twenex Emacs?
("In MDDT, no one can hear you scream -- but everybody can hear you say `whoops!'" --VAF@CMU-CS-C) ANONYMOUS: Username available to anybody at all who had network access and wanted to transfer some files to or from a Twenex machine.
ROLM DTI: Box used to interface a terminal to a ROLM data switch system which MIT received for free and spent a ridiculous amount of money installing.
Wheel: The top level in the hierarchy of Twenex privilege bits.
It differs from RMail in some respects, in particular: it will run on TENEX and TWENEX.
The remaining characters, which are those that have Control but not Meta with a basic character other than A{+Twenex:, B, D} - {+ITS:Y}{+Twenex:Z}, ], \, @@ and ^, cannot be typed conveniently on ASCII keyboards.
The only way to type them is to use the "controlizer" prefix character C-^, but this character is a nuisance to type.
My Programming Language History(Site not responding. Last check: 2007-10-05)
The first language I actually became fluent in; also the first language I ever got paid to program in.
The first language I actually wrote halfway-decent sizable code in, developed a personal subroutine library for, wrote multi-platform code in, and used on an IBM mainframe (Spitbol -- but I did all my development under Twenex with Sitbol, thank goodness).
