ALGOL and is
ALGOL ( short for ALGOrithmic Language ) is a family of imperative computer programming languages originally developed in the mid 1950s which greatly influenced many other languages and was the standard method for algorithm description used by the ACM, in textbooks, and academic works for the next 30 years and more.
Coral 66 is a general-purpose programming language based on ALGOL 60, with some features from Coral 64, JOVIAL, and FORTRAN.
A language is described as block-structured when it has a syntax for enclosing structures between bracketed keywords, such as an if-statement bracketed by as in ALGOL 68, or a code section bracketed by, as in PL / I-or the curly braces of C and many later languages.

ISWIM variables did not have explicit type declarations and it seems likely ( although not explicitly stated in the 1966 paper ) that Landin intended the language to be dynamically typed, like LISP and unlike ALGOL ; but it is also just possible that he had in mind to develop some form of type inference.

This is a reference to the work he had done as a member of the team that developed the ALGOL programming language.
The Burroughs ALGOL syntax, unlike the official language, requires that each variable ( or other object ) be declared before it is used, so it is feasible to write an ALGOL compiler that reads the data only once.
The notion of blocks is introduced by different syntax in different languages, but there are two broad families: the ALGOL family in which blocks are delimited by the keywords and, and the C family in which blocks are delimited by curly braces and.

ALGOL and programming
The earliest high-level programming languages, including FORTRAN ( 1957 ), COBOL ( 1960 ), and ALGOL 60 ( 1960 ), had support for multi-dimensional arrays, and so has C ( 1972 ).
It was developed by Tony Brooker and Derrick Morris as a variant of the ALGOL programming language, removing some Algol features such as " passing parameters by name " ( which in Algol 60 means passing the address of a short subroutine to recalculate the parameter each time it was mentioned ).
Their machine instruction sets favored one or many high level programming languages, such as ALGOL, COBOL or FORTRAN.
Like most imperative languages in the ALGOL tradition, C has facilities for structured programming and allows lexical variable scope and recursion, while a static type system prevents many unintended operations.

At the end of the 1950s, the language formalized as ALGOL 60 was introduced, and most later programming languages are, in many respects, descendants of Algol.
Some of the languages initially used for structured programming languages include: ALGOL, Pascal, PL / I and Ada – but most new procedural programming languages since that time have included features to encourage structured programming, and sometimes deliberately left out features in an effort to make unstructured programming more difficult.
