ALGOL N (N for Nippon – Japan in Japanese) is the name of a successor programming language to ALGOL 60, [1] [2] designed in Japan with the goal of being as simple as ALGOL 60 but as powerful as ALGOL 68. The language was proposed by Nobuo Yoneda. ALGOL N tried to use extensibility to solve the problem that language designers faced when trying to make an inextensible language for all domains, or having to make many domain-specific languages (DSLs), one for each domain. It avoided type conversion (coercion) while not making things more difficult for programmers.
ALGOL is a family of imperative computer programming languages originally developed in 1958. ALGOL heavily influenced many other languages and was the standard method for algorithm description used by the Association for Computing Machinery (ACM) in textbooks and academic sources for more than thirty years.
Simula is the name of two simulation programming languages, Simula I and Simula 67, developed in the 1960s at the Norwegian Computing Center in Oslo, by Ole-Johan Dahl and Kristen Nygaard. Syntactically, it is an approximate superset of ALGOL 60, and was also influenced by the design of Simscript.
Pretty-printing is the application of any of various stylistic formatting conventions to text files, such as source code, markup, and similar kinds of content. These formatting conventions may entail adhering to an indentation style, using different color and typeface to highlight syntactic elements of source code, or adjusting size, to make the content easier for people to read, and understand. Pretty-printers for source code are sometimes called code formatters or beautifiers.
ALGOL 60 is a member of the ALGOL family of computer programming languages. It followed on from ALGOL 58 which had introduced code blocks and the begin
and end
pairs for delimiting them, representing a key advance in the rise of structured programming. ALGOL 60 was one of the first languages implementing function definitions. ALGOL 60 function definitions could be nested within one another, with lexical scope. It gave rise to many other languages, including CPL, PL/I, Simula, BCPL, B, Pascal, and C. Practically every computer of the era had a systems programming language based on ALGOL 60 concepts.
ALGOL 68 is an imperative programming language that was conceived as a successor to the ALGOL 60 programming language, designed with the goal of a much wider scope of application and more rigorously defined syntax and semantics.
In computer programming, a statement is a syntactic unit of an imperative programming language that expresses some action to be carried out. A program written in such a language is formed by a sequence of one or more statements. A statement may have internal components.
ALGOL 58, originally named IAL, is one of the family of ALGOL computer programming languages. It was an early compromise design soon superseded by ALGOL 60. According to John Backus
The Zurich ACM-GAMM Conference had two principal motives in proposing the IAL: (a) To provide a means of communicating numerical methods and other procedures between people, and (b) To provide a means of realizing a stated process on a variety of machines...
Nobuo Yoneda was a Japanese mathematician and computer scientist.
Jensen's device is a computer programming technique that exploits call by name. It was devised by Danish computer scientist Jørn Jensen, who worked with Peter Naur at Regnecentralen. They worked on the GIER ALGOL compiler, one of the earliest correct implementations of ALGOL 60. ALGOL 60 used call by name. During his Turing Award speech, Naur mentions his work with Jensen on GIER ALGOL.
Transcription regulator protein BACH1 is a protein that in humans is encoded by the BACH1 gene.
Transcription regulator protein BACH2 is a protein that in humans is encoded by the BACH2 gene. It contains a BTB/POZ domain at its N-terminus which forms a disulphide-linked dimer and a bZip_Maf domain at the C-terminus.
Dartmouth ALGOL 30 was a 1960s-era implementation, first of the ALGOL 58 programming language and then of ALGOL 60. It is named after the computer on which it ran: a Librascope General Precision (LGP-30) desk-size computer acquired by Dartmouth College in 1959.
