Ken Thompson was very familiar with an earlier editor known as qed from University of California at Berkeley, Ken Thompson's alma mater ; he reimplemented qed on the CTSS and Multics systems, so it is natural that he carried many features of qed forward into ed.

MIT's CTSS, one of the first time sharing systems, was introduced in 1961.

Ken Thompson later wrote a version for CTSS ; this version was notable for introducing regular expressions.

CTSS was written in a dynamic memory Fortran first named LRLTRAN which ran on CDC 7600s and renamed CVC ( pronounced " Civic ") when vectorization for the Cray-1 was added.

It was widely used to teach programming at colleges and universities during the 1960s and played a minor role in the development of CTSS, Multics, and the Michigan Terminal System computer operating systems.

I was writing in MAD, which was much easier and more pleasant than the FORTRAN and COBOL that I had written earlier, and I was using CTSS, the first time-sharing system, which was infinitely easier and more pleasant than punch cards.

* The Compatible Time-Sharing System ( CTSS ), one of the first time-sharing operating systems, was developed at MIT's Project MAC using a 7094 with an extra bank of memory, among other modifications.

( CTSS was used as an early CP / CMS development platform.

It was a descendant of the RUNOFF program from CTSS, the first computerized text-formatting program, and is a predecessor of the Unix troff document processing system.

It was written in 1964 for the CTSS operating system by Jerome H. Saltzer in MAD assembler.

Likewise, RUNOFF for CTSS was the predecessor of the various RUNOFFs for DEC's operating systems, via the RUNOFF developed by the University of California, Berkeley's Project Genie for the SDS 940 system.

It was a Unix version of the runoff text-formatting program from Multics, which was a descendant of RUNOFF for CTSS ( the first computerized text-formatting application ).

The Compatible Time-Sharing System, or the CTSS, was one of the first time-sharing operating systems ; it was developed at MIT's Computation Center.

CTSS was first demonstrated in 1961, and was operated at MIT until 1973.

CTSS was very influential.

Multics, which was also developed by Project MAC, was started in the 1960s as a successor to CTSS, for future use in multiple-access computing.

# Original MAD, the compiler developed in 1959 at the University of Michigan for the IBM 704 and later the IBM 709 and IBM 7090 mainframe computers running the University of Michigan Executive System ( UMES ) and the Compatible Time-Sharing System ( CTSS ) operating systems.

CTSS may also stand for Compatible Time Sharing System, an unrelated operating system developed by the MIT Computer Centre.

CTSS has its final breaths running on Cray instruction-set-compatible hardware developed by Scientific Computer Systems ( SCS-40 and SCS-30 ) and Supertek S-1, but this did not save the software.

File names in CTSS had two parts, a user-readable " primary name " and a " secondary name " indicating the file type.

In large machines there were other disk operating systems, such as IBM's VM, DEC's RSTS / RT-11 / VMS / TOPS-10 / TWENEX, MIT's ITS / CTSS, Control Data's assorted NOS variants, Harris's Vulcan, Bell Labs ' Unix, and so on.

Many of the text elements are found in the 1988 ISO technical report TR 9537 Techniques for using SGML, which in turn covers the features of early text formatting languages such as that used by the RUNOFF command developed in the early 1960s for the CTSS ( Compatible Time-Sharing System ) operating system: these formatting commands were derived from the commands used by typesetters to manually format documents.

It is not known, but entirely possible that this traces its lineage from the CTSS editor.

Similar facilities existed on earlier system such as Multics and CTSS Early versions talk did not separate text from each user.

troff can trace its origins back to a text formatting program called RUNOFF, written by Jerome H. Saltzer for MIT's CTSS operating system in the mid-1960s.

* Dave Pitts ' IBM 7094 support – Has a CTSS environment that includes the MIT version of MAD.

Though the term dates from the 1990s, instant messaging predates the Internet, first appearing on multi-user operating systems like Compatible Time-Sharing System ( CTSS ) and Multiplexed Information and Computing Service ( Multics ) in the mid-1960s.

The CMS user interface drew heavily on experience with the influential first-generation time-sharing system CTSS, some of whose developers worked on CP / CMS.

A few weeks later the maps were being divided into squares and a position was described as being `` about lots 239, 247 and 272 with pickets forward as far as 196 ''.

Edward Rawson, secretary of the colony of Massachusetts Bay, described him as `` a man whose spirit was stark drunk with blasphemies and insolence, a corrupter of the truth, a disturber of the peace wherever he comes ''.

Both abolition of war and new techniques of production, particularly robot factories, greatly increase the world's wealth, a situation described in the following passage, which has the true utopian ring: `` Everything was so cheap that the necessities of life were free, provided as a public service by the community, as roads, water, street lighting and drainage had once been.

Much of his earlier work was conceived in terms of a `` pseudo-anthropological '' myth reference, which is concerned with imaginary places and beings described in grandiloquent and travelogue-like language.

He was discharged from the hospital after a two-day checkup and he and his parents had what Mr. McKinley described as a `` celebration lunch '' at the cafeteria on the campus.

The instrument used for this work was a slight modification of that previously described.

This sample was contained in a cylindrical container similar to that described above.

Purified inactive chlorine was then added from one of the tubes described above and the mixture frozen out and sealed off in a flask equipped with a break seal.

The saline and albumin tests were performed as described for the ABO samples except that the mixture was incubated for 1 hr at 37-degrees-C before centrifugation.

The deep concave gradient employed ( fig. 2 ) was obtained with a nine-chambered gradient elution device ( `` Varigrad '', reference ( 8 ) ) and has been described elsewhere.

When paper electrophoresis was to be used for preparation, eight strips of a whole serum sample or a chromatographic fraction concentrated by negative pressure dialysis were run/chamber under the conditions described above.

With due consideration for the limits of precision in assessing, expected rate of change in ossification of girls age 2 years, and the known variations in rate of ossification of these children as described in our preceding paper in the Supplement, each arrow with a `` shaft length '' of four months or less was selected as indicating `` same schedule '' at Onset and Completion, for this particular epiphysis.

In contrast to the nuclear changes described above, another change in muscle nuclei was seen, usually occurring in fibers that were somewhat smaller than normal but that showed distinct cross-striations and myofibrillae.

The technique of cutting sections was essentially the same as that described by Coons et al ( 1951 ).

This conjugate was passed twice through Dowex-2-chloride and treated with various tissue powders in the same manner as described for the indirect method.

How this was accomplished may be described, since this sometimes is a crucial problem.

This illusion was described in a far-sighted editorial in The New York Herald Tribune, on March 5, 1947, in connection with the submission of the satellite peace treaties to the Senate.

He had what was described by a psychologist as a `` sunny brutality ''.

He described the piece as a " rhapsodic ballet " because it was written freely and is more modern than his previous works.

The private transaction was reported in a 2009 article in The Economist, which described Warhol as the " bellwether of the art market ".

It was the cover story of the issue of Astounding that is sometimes described as having ushered in the " Golden Age " of science fiction.

This was the case, for instance, in the Weapon Shop series, the Mixed Men series and in single stories such as " Heir Apparent ", whose protagonist was described as a " benevolent dictator ".

Thus, the planetary model of the atom was discarded in favor of one that described atomic orbital zones around the nucleus where a given electron is most likely to be observed.
