The Jargon File

A Chronology...The Jargon FileComputer Dictionary
(tee'koe) [acronym for Text Editor and COrrector]1. n. A text editor developed at MIT, and modified by just about everybody. If all the dialects are included, TECO might well be the single most prolific editor in use. Noted for its powerful pseudo-programming features and its incredibly hairy syntax.
2. v. To edit using the TECO editor in one of its infinite forms; sometimes used to mean "to edit" even when not using TECO! Usage: rare at SAIL, where most people wouldn't touch TECO with a TENEX pole.
[Historical note: DEC grabbed an ancient version of MIT TECO many years ago when it was still a TTY-oriented editor. By now, TECO at MIT is highly display-oriented and is actually a language for writing editors, rather than an editor. Meanwhile, the outside world's various versions of TECO remain almost the same as the MIT version of ten years ago. DEC recently tried to discourage its use, but an underground movement of sorts kept it alive.]
[Since this note was written I found out that DEC tried to force their hackers by administrative decision to use a hacked up and generally lobotomized version of SOS instead of TECO, and they revolted. - MRC]
v. To communicate with another ARPAnet host using the TELNET protocol. TOPS-10 people use the word IMPCOM since that is the program name for them. Sometimes abbreviated to TN. "I usually TN over to SAIL just to read the AP News."
adj. Of programs, very clever and efficient. A tense piece of code often got that way because it was highly bummed, but sometimes it was just based on a great idea. A comment in a clever display routine by Mike Kazar: "This routine is so tense it will bring tears to your eyes. Much thanks to Craig Everhart and James Gosling for inspiring this hack attack." A tense programmer is one who produces tense code.
(tur'pree) [from the LISP 1.5 (and later, MacLISP) function to start a new line of output] v. To output a CRLF (q.v.).
n. Used in the general sense of idea, plan, story, or set of rules. "What's the theory on fixing this TECO loss?" "What's the theory on dinner tonight?" ("Chinatown, I guess.") "What's the current theory on letting losers on during the day?" "The theory behind this change is to fix the following well-known screw..."
