View source for TECO

'''TECO''' is a powerful but complex [[text editor]].  It was first written 1962 for a [[PDP-1]] at [[Massachusetts Institute of Technology|MIT]]'s [[Research Laboratory of Electronics]], and then ported to the [[Project MAC]] [[PDP-6]] in 1964. It was for a long time the primary editor on [[Incompatible Timesharing System|ITS]].  [[EMACS]] was implemented using TECO's programming facilities.

The standalone PDP-6 version was modified in 1966 by Bob Clements, while installing the [[Stanford Artificial Intelligence Laboratory|SAIL]] PDP-6, to run on the [[DEC]] Monitor.  This evolved into DEC's "Standard TECO"; TECO was also re-written for many other computers, and spread fairly widely. A version was written for the [[PDP-11]] (in [[MACRO-11]]) at MIT.

==TECO humour==

Dave Moon started a humorous term at MIT: 'TECO madness; a moment of convenience, a lifetime of regret'. (This is based on the tag-line from the old movie, ''Reefer Madness'': "A moment of bliss; a lifetime of regret!"). Obviously, Moon had written some complicated TECO command string to perform some complex change, and gotten it wrong - and it promptly ate something he had spent a considerable time typing in.
