ALGOL (short for ALGO rithmic L anguage) is a programming language originally developed in the mid 1950's which became the de facto standard way to report algorithms in print for almost the next 30 years.
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 68 was defined using a two-level grammar formalism invented by Adriaan van Wijngaarden and which bears his name.

 ALGOL - Wikipedia, the free encyclopedia
ALGOL (short for ALGO rithmic L anguage) 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.
The Burroughs Corporation 's B5000 and its successors were stack machines designed to be programmed in an extended variant of ALGOL 60, known as Elliot ALGOL ; indeed their operating system, or MCP (Master Control Program) as they are called, was written in Elliot ALGOL as far back as 1961.

ALGOL 58 was originally known as the IAL (for I nternational A lgorithmic L anguage.) ALGOL 58 is the first language in the ALGOL programming language family.
ALGOL 68 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.
Elliot ALGOL (also known simply as Extended ALGOL) was the Burroughs-specific extension of the ALGOL 60 programming language designed system and application programming in its B5000 mainframes.

ALGOL is a systems-programming language, and while B5000 was designed specifically around ALGOL, this was only a startingpoint.
The visibility rules of ALGOL (as a language designed forsingle pass compilers) mean that only variables declared before the current position are visible at that part of the code (apartfrom forward declarations).

ALGOL (abbreviazione di ALGO rithmic L anguage, ossia linguaggio algoritmico) è un linguaggio di programmazione sviluppato nel 1958.
Di queste, solo ALGOL 60 si è diffusa ( Niklaus Wirth basò il proprio Algol-W sull'ALGOL 60 prima di cominciare a sviluppare il Pascal).
ALGOL 60 ufficialmente non possedeva istruzioni di I/O; le varie implementazioni necessariamente dovettero implementarle ma il modo variava da un'implementazione all'altra.

It was Niklaus Wirths proposal for a successor to ALGOL 60 in the ALGOL 68 committee.
It represented a relatively conservative modification of ALGOL 60, to ALGOL 60 Wirth added Character-string-(computer-science), bitstring, complex number and Reference-(computer-science) to Composite-type datatype and a Parameter-(computer-science) but changed little else.
The language that eventually became ALGOL 68 is much larger and more complex than Algol-W, and it differs more from Algol 60 than Algol-W does.

NEWP too was an ALGOL extension, but it was more secure than ALGOL, in fact most low-level operating system calls were rejected by the NEWP compiler unless a block was specifically marked to allow those instructions.

I have almost no memory of which book on ALGOL I had in school in 1973, although it would have been for the Burroughs 6700 computer, and therefore probably for Elliot Algol.
I found ALGOL quite easy to learn since I had already learned two other imperative languages that were very similar.
Although all ALGOL texts emphasize that the language allows a mixture of upper and lower case letters, I don't remember that aspect of the ALGOL version we used.

Pat was very pleased with Hoare´s completed program, but Hoare had something to add… when he was studying machine translation of languages in Moscow, one of the things he was doing was a program to do automatic search of words in a dictionary, and by that time he used a sorting algorithm that he created.
But now in Elliot Brothers, he realised that this algorithm was faster than the one invented by Shell, so he tried to convince his boss of this but although his method was very hard to explain, his boss finally agreed with him.
It was based on that of the conditional expression of Algol 60, which selects between two alternative actions according to the value of a boolean expression.

He worked from 1960 to 1968 at Elliot Brothers, a pioneering UK company which developed computers and was later, by several steps, merged into ICL.
A high point for formal methods was Hoare's development of an Algol compiler implementing the Algol 60 definition.
Hoare left Elliot Brothers in 1968 and eventually arrived at Oxford's Computing Laboratory, a consistent centre of expertise in formal methods.
