TYPSET is an early document editor that was used with the 1964-released RUNOFF program, one of the earliest text formatting programs to see significant use.
12-419: Of two earlier print/formatting programs DITTO and TJ-2 , only the latter had, and introduced, text justification ; RUNOFF also added pagination . The name RUNOFF, and similar names led to other formatting program implementations. By 1982, Runoff (a name not possible before lowercase letters were introduced to filenames) largely became associated with Digital Equipment Corporation and Unix computers. DEC used
24-504: Is a direct predecessor of the runoff document formatting program of Multics , which in turn was the ancestor of the roff and nroff document formatting programs of Unix , and their descendants. It was also the ancestor of FORMAT for the IBM System/360 , and of course indirectly of every computerized word processing system. Likewise, RUNOFF for CTSS was the predecessor of the various RUNOFFs for DEC 's operating systems, via
36-657: Is thought to be the first page layout program. Although it lacks page numbering , page headers and footers , TJ-2 is the first word processor to provide a number of essential typographic alignment and automatic typesetting features: Developed from two earlier Samson programs, Justify and TJ-1, TJ-2 was written for the PDP-1 that was donated to the Massachusetts Institute of Technology in 1961 by Digital Equipment Corporation . Taking English text as input, TJ-2 aligns left and right margins, justifying
48-614: The CTSS operating system. TYPSET and RUNOFF soon evolved into runoff for Multics , which was in turn ported to Unix in the 1970s as roff . A similar program for the ITS PDP-6 and later the PDP-10 was TJ6 . Expensive Typewriter Expensive Typewriter was a pioneering text editor program that ran on the DEC PDP-1 computer, which had been delivered to MIT in
60-523: The EDT text editor under the VS/9 operating system . These different releases of Runoff typically had little in common except the convention of indicating a command to Runoff by beginning the line with a period. The origin of IBM's SCRIPT software began in 1968 when IBM contracted Stuart Madnick of MIT to write a simple document preparation tool for CP/67 , which he modelled on MIT 's CTSS RUNOFF. RUNOFF
72-652: The RUNOFF developed by the University of California, Berkeley 's Project Genie for the SDS 940 system. The name is alleged to have come from the phrase at the time, I'll run off a copy . TYPESET contains features inspired by a variety of other programs including Colossal Typewriter and Expensive Typewriter . Input: Output: TJ-2 TJ-2 ( Type Justifying Program ) was published by Peter Samson in May 1963 and
84-457: The early 1960s. Since the program could drive an IBM Selectric typewriter (a letter-quality printer ), it may be considered the first word processing software. It was written and improved between 1961 and 1962 by Steve Piner and L. Peter Deutsch . In the spirit of an earlier editor program, named " Colossal Typewriter ", it was called "Expensive Typewriter" because at that time the PDP-1 cost
96-403: The output using white space and word hyphenation. Text is marked-up with single lowercase characters combined with the PDP-1's overline character, carriage returns, and internal concise codes. The computer's six toggle switches control the input and output devices, enable and disable hyphenation and stop the session. Words can be hyphenated with a light pen on the computer's CRT display and from
108-403: The session's dictionary in memory. On-screen hyphenation has SAVE and FORGET commands and OOPS , the undo . Comments in the code were quoted thirty years later: "The ways of God are just and can be justified to man" and "Girls who wear pants should be sure that the end justifies the jeans." TJ-2 was succeeded by TYPSET and RUNOFF , a pair of complementary programs written in 1964 for
120-671: The terms VAX DSR and DSR to refer to VAX DIGITAL Standard Runoff . The original RUNOFF type-setting program for CTSS was written by Jerome H. Saltzer circa 1964. Bob Morris and Doug McIlroy translated that from MAD to BCPL . Morris and McIlroy then moved the BCPL version to Multics when the IBM 7094 on which CTSS ran was being shut down. Documentation for the Multics version of RUNOFF described it as "types out text segments in manuscript form." A later version of runoff for Multics
132-519: Was written in PL/I by Dennis Capps, in 1974. This runoff code was the ancestor of roff that was written for the fledgling Unix in assembly language by Ken Thompson . Other versions of Runoff were developed for various computer systems including Digital Equipment Corporation 's PDP-11 minicomputer systems running RT-11 , RSTS/E , RSX on Digital's PDP-10 and for OpenVMS on VAX minicomputers, as well as UNIVAC Series 90 mainframes using

#1732772221165144-478: Was written in 1964 for the CTSS operating system by Jerome H. Saltzer in MAD and FAP . It actually consisted of a pair of programs, TYPSET (which was basically a document editor), and RUNOFF (the output processor). RUNOFF had support for pagination and headers, as well as text justification ( TJ-2 appears to have been the earliest text justification system, but it did not have the other capabilities). RUNOFF
