TECO may be used to edit any form of ASCII text such as program listings, manuscripts, correspondence and the like. Since TECO IS a character-oriented editor rather than a line editor, text edited with TECO does not have line numbers associated with it, nor is it necessary to replace an entire line of text in order to change one character.

  • Lisp: Program Is Data
    LISP: PROGRAM IS DATA A HISTORICAL PERSPECTIVE ON MACLISP Jon L White Laboratory for Computer Science, M.I.T.* ABSTRACT For over 10 years, MACLISP has supported a variety of projects at M.I.T.'s Artificial Intelligence Laboratory, and the Laboratory for Computer Science (formerly Project MAC). During this time, there has been a continuing development of the MACLISP system, spurred in great measure by the needs of MACSYMAdevelopment. Herein are reported, in amosiac, historical style, the major features of the system. For each feature discussed, an attempt will be made to mention the year of initial development, andthe names of persons or projectsprimarily responsible for requiring, needing, or suggestingsuch features. INTRODUCTION In 1964,Greenblatt and others participated in thecheck-out phase of DigitalEquipment Corporation's new computer, the PDP-6. This machine had a number of innovative features that were thought to be ideal for the development of a list processing system, and thus it was very appropriate that thefirst working program actually run on thePDP-6 was anancestor of thecurrent MACLISP. This earlyLISP was patterned after the existing PDP-1 LISP (see reference l), and was produced by using the text editor and a mini-assembler on the PDP-1. That first PDP-6 finally found its way into M.I.T.'s ProjectMAC for use by theArtificial lntelligence group (the A.1. grouplater became the M.I.T. Artificial Intelligence Laboratory, and Project MAC became the Laboratory for Computer Science). By 1968, the PDP-6 wasrunning the Incompatible Time-sharing system, and was soon supplanted by the PDP-IO.Today, the KL-I 0, anadvanced version of thePDP-10, supports a variety of time sharing systems, most of which are capable of running a MACLISP.

SCHOLZ The Medical CoUege ofPenmylvanill., Division ofSocial Science, 11&e Department ofPsychiatry, PhikulelphiD., Penmylvania19129 A timesharing system for the Digital Equipment Corporation PDP-11 is described. In keeping with the general philosophy ofthe RT-11 operating system, the permanently resident portion of the system is kept to an absolute minimum size. The system supports from 2 to 16 users, and provides each with full editing and batch execution capabilities. A majority of the users of the Digital Equipment manager to load and execute the nonresident overlays, Corporation PDP-II in scientific and academic environ­ and a collection of routines to handle input/output ments have chosen the RT-II operating system as the and interactive text editing. system which offers the greatest range of facilities with 2.

However, despite its versatility, RT-11 system.

    Eric Roberts Handout #25 CS 106B February 4, 2015 Editor Buffers Why Look at Old Editors? • In today’s class and again on Friday, I’m going to look at an ancient (at least in the sense of Internet time) editor Editor Buffers technology, which is largely based on the TECO (Text Editor and COrrector) I used to prepare my doctoral thesis. • Some of you will no doubt greet this idea with skepticism. Why should you study something so old that doesn’t meet even the most requirements we would insist on in an editor? • We’ve kept that editor in CS 106B for two decades because: Eric Roberts – It’s absolutely the best example of how using different data representations can have a profound effect on performance. CS 106B – No modern editor is simple enough to understand in its entirety. February 4, 2015 – TECO is historically important as the first extensible editor. It was the first platform for EMACS, which is still in use today. – The strategies we describe for representing the editor persist in modern editor classes, such as Java’s JEditPane. WYSIWYG vs. Command Line The PDP-1 Computer • A great deal of early graphics development was done on the • Most editors today follow the WYSIWYG principle, which is Digital Equipment Corporation’s PDP-1 computer, which was an acronym for “what you see is what you get” that keeps the released in 1959.

  • An Introduction to the EMACS Editor
    MASSACHUSETTS INSTITUTE OF TECHNOLOGY ARTIFICIAL INTELLIGENCE LABORATORY AI Memo No. 447 November 1977 An Introduction to the EMACS Editor by Eugene Ciccarelli » Abstract: The intent of this memo is to describe EMACS in enough detail to allow a user to edit comfortably in most circumstances, knowing how to get more information if needed. Basic commands described cover buffer editing, file handling, and getting help. Two sections cover commands especially useful for editing LISP code, and text (word- and paragraph-commands). A brief "cultural interest" section describes the environment that supports EMACS commands. EMACS Introduction 2 9 December 1977 Preface This memo is aimed at users unfamiliar not only with the EMACS editor, but also with the ITS operating system. However, those who have used ITS before should be able to skip the few ITS-related parts without trouble. Newcomers to EMACS should at least read sections 1 through 5 to start with. Those with a basic knowledge of EMACS can use this memo too, skipping sections (primarily those toward the beginning) that they seem to know already.
