	BCPL - Wikipedia, the free encyclopedia
		BCPL (Basic Combined Programming Language) is a computer programming language that was designed by Martin Richards of the University of Cambridge in 1966; it was originally intended for use in writing compilers for other languages.
		BCPL was a response to difficulties with its predecessor CPL, created during the early 1960s; Richards created BCPL by "removing those features of the full language which make compilation difficult".
		BCPL is reputedly the language in which the original hello world program was written.

	Programming language - Wikipedia, the free encyclopedia
		Programming languages are used to facilitate communication about the task of organizing and manipulating information, and to express algorithms precisely.
		The combination of the language definition, the program, and the program's inputs must fully specify the external behavior that occurs when the program is executed.
		Programming language syntax is usually defined using a combination of regular expressions (for lexical structure) and Backus-Naur Form (for grammatical structure).

	C programming language
		C is a programming language, designed by Dennis Ritchie during the early 1970s, for writing the UNIX operating system.
		BCPL was in turn descended from an earlier Algol-derived language, CPL.
		By 1973, the C language had became powerful enough that most of the kernel of the Unix operating system was reimplemented in C. This was the first time that the kernel of an operating system had been implemented in a high level language.

	The History of Computer Programming Languages
		Computer languages were first composed of a series of steps to wire a particular program; these morphed into a series of steps keyed into the computer and then executed; later these languages acquired advanced features such as logical branching and object orientation.
		Visual Basic is often taught as a first programming language today as it is based on the BASIC language developed in 1964 by John Kemeny and Thomas Kurtz.
		The first major languages were characterized by the simple fact that they were intended for one purpose and one purpose only, while the languages of today are differentiated by the way they are programmed in, as they can be used for almost any purpose.

		Although not widely used now, it was very influential, because Dennis Ritchie would later develop the widely-used C programming language from BCPL.
		The language is unusual in having only one data type: a word, a fixed number of bits, usually chosen to align with the architecture's machine word.
		It is reputedly the language in which the original hello world program was written.

		BCPL is low-level, typeless and block-structured, and provides only one-dimensional arrays.
		Program segments communicate via the global vector where system and user variables are stored in fixed numerical locations in a single array.

	C programming language - Article from FactBug.org - the fast Wikipedia mirror site
		The C programming language is a low-level standardized programming language developed in the early 1970s by Ken Thompson and Dennis Ritchie for use on the UNIX operating system.
		C is a relatively minimalist programming language that operates close to the hardware, and is more similar to assembly language than most other programming languages.
		By 1973, the C language had become powerful enough that most of the UNIX kernel, originally written in PDP-11/20 assembly language, was rewritten in C. This was one of the first operating system kernels implemented in a language other than assembly, earlier instances being the Multics system (written in PL/I) and TRIPOS (written in BCPL).

		The C programming language and its direct descendants are by far the most popular programming languages used in the world today.
		This paper will explore the history of the C programming language and discuss the different aspects of the language in an attempt to determine why this language has thrived in spite of there being more powerful and better structured object oriented languages in existence.
		C is now such a popular programming language that there have been several descendants from it that are in wide use.

	1951 - 1970
		PL/I (Programming Language 1) is a large, complex block-structured language invented by IBM in 1963, and first released in 1964 in conjunction with the influential System/360 line of computers.
		BCPL was an early block-structure procedural language, fairly low-level, and used for system and small application programming.
		It would develop into the inspiration for two systems programming languages developed at Bell Telephone Laboratories in the 1970's, B and C. BCPL is an operator-typed language; the data types of variables are defined by the operators applied (rather than being declared for the variable, as in Algol).

	GNE: the C programming language
		C is a high-level imperative programming language, which characteristically provides a very close correspondence between high-level language statements and machine-language instructions.
		C++ is an object-oriented programming language directly descended from C. Its initial development by Bjarne Stroustrup occurred in the early 1980s, and consisted of some simple additions to the C language to make the handling of basic class structures with member functions and polymorphism easier.
		The language gives a number of partial guarantees about the representation of certain data types, and the relationships between them, allowing the programmer to implement many operations by direct manipulation of bits in memory, essentially using the C language as a portable machine language.

		Because of this, the Unix operating system which was originally written in assembly language, was almost immediately re-written in C (only the assembly language code needed to "bootstrap" the C code was kept).

		The C programming language is used in many different areas of application, but the most prolific area is UNIX operating system applications.

	A brief(ish) description of BCPL
		I first encountered BCPL when I was at Cambridge University, the home of the language and its designer, Martin Richards.
		BCPL was the systems programming language of choice at Cambridge, because it generated code better than the IBM Fortran compilers while not requiring the agony of Assembler.
		BCPL implementations are available from Martin Richards, or from the old BCPL distribution.

	Language Reference - C
		BCPL was studied by the staff at Bell Labs, who were creating the UNIX operating system.
		In 1972, Dennis Ritchie designed the language he called C. In 1978 he and Kernighan published a book on C, and this (K&R C) became the defning document for the language until around 10 years later when an ANSI C was completed.
		One of the main reasons that C has gained such prominence is because much of UNIX is written in C. In 1989, the ANSI standards committee agreed to a C standard, X3.159- 1989.
