(though probably not a useful one); one common game used to be mentally working out what the TECO commands corresponding to human names did. 2. vt. Originally, to edit using the TECO editor in one of its infinite variations (see below). 3. vt.,obs. To edit even when TECO is not the editor being used! This usage is rare and now primarily historical. |

As an example of TECO's obscurity, here is a TECO program that takes a list of names such as: |
|
|
|
 |
|
|
|
|
Loser, J. Random
Quux, The Great
Dick, Moby |
|
|
|
|
|
|
|
|
sorts them alphabetically according to surname, and then puts the surname last, removing the comma, to produce the following: |
|
|
|
|
|
|
|
|
Moby Dick
J. Random Loser
The Great Quux |
|
|
|
|
|
|

[1 JP$L$$
J . -Z; ., (S,$ -D .)FX1 @FB $K :L I $ G1 L$$ |
|
|
|
|
|
|
|
|
(where B means 'Control-B' (ASCII 0000010) and $ is actually an alt or escape (ASCII 0011011) character). |

In fact, this very program was used to produce the second, sorted list from the first list. The first hack at it had a bug: GLS (the author) had accidentally omitted the @ in front of FB, which as anyone can see is clearly the Wrong Thing. It worked fine the second time. There is no space to describe all the features of TECO, but it may be of interest that P means 'sort' and J. -Z; L is an idiomatic series of commands for 'do once for every line'. |

In mid-1991, TECO is pretty much one with the dust of history, having been replaced in the affections of hackerdom by EMACS. Descendants of an early (and somewhat lobotomized) version adopted by DEC can still be found lurking on VMS and a couple of crufty PDP-11 operating systems, however, and ports of the more advanced MIT versions remain the focus of some antiquarian interest.
