	ALGOL - Wikipedia, the free encyclopedia
		ALGOL (short for ALGOrithmic Language) is a family of imperative computer programming languages originally developed in the mid 1950s which became the de facto standard way to report algorithms in print for almost the next 30 years.
		Algol-W was intended to be the next generation ALGOL, but the majority of the ALGOL 68 committee decided to design a language that was more complex and advanced rather than a language that is basically a cleaned up version of ALGOL 60.
		ALGOL 68 was defined using a two-level grammar formalism invented by Adriaan van Wijngaarden and which bears his name.

	ALGOL 68 - Wikipedia, the free encyclopedia
		ALGOL 68 (short for ALGOrithmic Language 1968) is an imperative computer 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 a more rigorously defined syntax and semantics.
		Contributions of ALGOL 68 to the field of computer science are deep and wide ranging, although some of them were not publicly identified until they were passed, in one form or another, to one of many subsequently developed programming languages.
		ALGOL 68 was defined using a two-level grammar formalism invented by Adriaan van Wijngaarden.

		The design of Algol 68 was firmly rooted in the Computing Community, a contemporary term of the small but growing international community of computer professionals and scientists, whose eyes had been opened by Algol 60, and who were giving shape to the Science and practice of Informatics [14].
		Algol 68, unlike its predecessor Algol 60, intended to be a general purpose language [1], which at the time meant there was emphasis on scientific and numerical applications.
		Algol 68 was designed to communicate algorithms, to execute them efficiently on a variety of different computers, and to aid in teaching them to students.

		Algol 68 was defined in a formal document, first published in January 1969, and later published in Acta Informatica and also printed in Sigplan Notices.
		Algol 68 was the first major language for which a full formal definition was made before it was implemented.
		Another factor that hindered Algol 68 from spreading more widely is that Algol 68 was designed for programmers, not for compiler writers, in a time when the field of compiler construction was not as advanced as it is today.

		Algol 60 reworked some of the ideas of Algol 58, and even without the support of IBM, it was implemented and achieved partial success across the US and Europe.
		C++ also inherited much from Algol 68, both directly and indirectly, and is commonly cited as being the closest living relative of modern days [12].
		Disregarding the fact that C++ is an object-oriented language (Algol 68 was procedural), it inherits all of the concepts that C took from Algol 68 - including compound types, block structures and pointers.

		Hoare's "ALGOL was a great improvement on its successors." The full quote is "Here is a language so far ahead of its time, that it was not only an improvement on its predecessors, but also on nearly all its successors", but the aphoristic version is far better known.
		ALGOL 60 allowed for two types of parameter passing: call-by-value, and the innovation of call-by-name, which was later abandoned by its successor languages.
		ALGOL 68 was defined using a two-level grammar of the sort invented by Adriaan van Wijngaarden and which bears his name.

		The process of translating the report on Algol 68 into Russian followed the process of its up-to-dating in English so closely that both the Report and its Russian translation [1] were issued in the same year of 1969.
		Starting from 1976 the official national organization on Algol 68 began to act, under whose observation were the translation of the Revised Report, publishing of literature, testing and adopting of compilers.
		The complexity of Algol 68, intrinsic to it, has contributed to the fact that the language was nested primarily in the academic and university environment and did not find a large support in the industry.

		ALGOL 68 was meant to improve upon an already existing general-purpose programming language that had been well-established as the best language for formal analysis of programming to date.
		Arrays in ALGOL 68 are full of expressive power, and contribute to the language's usefulness in reasoning about general programming strategies.

		A SHORTER HISTORY OF ALGOL68 ALGOL 68 was defined in a document, first published in January 1969, and later published as Acta Informatica 5 (1975) (still available from Numerische Mathematik) and also printed as Sigplan Notices 12(5), 1977.
		This document (and its predecessor, the Draft Report on ALGOL 68 which was sent out in February 1968 to 1000 members of the "computing community") created at the time quite a stir in Computer Science: Many people found it extremely formal, and therefore unreadable.
		ALGOL 68 was the first (and possibly one of the last) major language for which a full formal definition was made before it was implemented.

	Algol-Like Languages, Introduction
		According to these criteria, languages such as Algol 68 and Pascal and their descendants are not Algol-like.
		While Algol's stack discipline was the original focus of functor-category semantics, the ideas have been used also to model dynamic allocation [PS93, Sta96a] and local names in the pi-calculus [Sta96b, FMS96].
		He formulates a functor-category model for a parallel version of Idealized Algol; the use of a functor category shows that the shape of the store is the same in the initial and final states in the evaluation of any command.
