The A-0 system (Arithmetic Language version 0), written by Richard K. Ridgway [1] (managed by Grace Hopper) in 1951 and 1952 for the UNIVAC I, was an early[2] compiler related tool developed for electronic computers.[3] The A-0 functioned more as a loader or linker than the modern notion of a compiler. A program was specified as a sequence of subroutines and arguments. The subroutines were identified by a numeric code and the arguments to the subroutines were written directly after each subroutine code. The A-0 system converted the specification into machine code that could be fed into the computer a second time to execute the said program. wiki.

It uses Java-like syntax, and included IDE integrations for displaying crosscutting structure since its initial public release in 2001. wiki.

47: Assembly language

An assembly (or assembler) language,[1] often abbreviated asm, is a low-level programming language, in which there is a very strong (but often not one-to-one) correspondence between the language and the architecture's machine code instructions. Each assembly language is specific to a particular computer architecture. In contrast, most high-level programming languages are generally portable across multiple architectures but require interpreting or compiling. Assembly language may also be called symbolic machine code.[2] wiki.

48: ATS

ATS (Applied Type System) is a programming language designed to unify programming with formal specification. ATS has support for combining theorem proving with practical programming through the use of advanced type systems.[1] A past version of The Computer Language Benchmarks Game has demonstrated that the performance of ATS is comparable to that of the C and C++ programming languages.[2] By using theorem proving and strict type checking, the compiler can detect and prove that its implemented functions are not susceptible to bugs such as division by zero, memory leaks, buffer overflow, and other forms of memory corruption by verifying pointer arithmetic and reference counting before the program compiles. Additionally, by using the integrated theorem-proving system of ATS (ATS/LF), the programmer may make use of static constructs that are intertwined with the operative code to prove that a function attains its specification. wiki.

49: Ateji PX

63: BCPL

BCPL ("Basic Combined Programming Language"; or 'Before C Programming Language' (a common humorous backronym)[3]) is a procedural, imperative, and structured computer programming language. Originally intended for writing compilers for other languages, BCPL is no longer in common use. However, its influence is still felt because a stripped down and syntactically changed version of BCPL, called B, was the language on which the C programming language was based. BCPL introduced several features of modern programming languages, including using curly braces to delimit code blocks; compilation via virtual machine byte code; and the world's first 'hello world' demonstrator program. wiki.

64: BeanShell

BeanShell is a Java-like scripting language, invented by Patrick Niemeyer. It runs in the Java Runtime Environment (JRE) and uses a variation of the Java syntax, in addition to scripting commands and syntax. wiki.

65: Batch (Windows/Dos)

A batch file is a kind of script file in DOS, OS/2 and Microsoft Windows. It consists of a series of commands to be executed by the command-line interpreter, stored in a plain text file. A batch file may contain any command the interpreter accepts interactively and use constructs that enable conditional branching and looping within the batch file, such as IF, FOR, and GOTO labels. The term "batch" is from batch processing, meaning "non-interactive execution", though a batch file may not process a batch of multiple data. wiki.

66: Bertrand

Bertrand (named after Bertrand Russell) is a computer programming language for creating constraint programming systems. The language was created by Wm Leler in the mid-1980s as part of his doctoral research.

69: BLISS

BLISS is a system programming language developed at Carnegie Mellon University by W. A. Wulf, D. B. Russell, and A. N. Habermann around 1970. It was perhaps the best known systems programming language right up until C made its debut a few years later. Since then, C took off and BLISS faded into obscurity. When C was in its infancy, a few projects within Bell Labs were debating the merits of BLISS vs. C[citation needed]. wiki.

70: Blockly

Blockly is a client-side JavaScript library for creating visual block programming languages and editors. It is a project of Google and is open-source under the Apache 2.0 License.[1] It typically runs in a web browser, and visually resembles Scratch. Blockly is also being implemented for Android and iOS; not all web browser based features are available for Android/iOS. wiki.

71: BlooP

BlooP and FlooP are simple programming languages designed by Douglas Hofstadter to illustrate a point in his book Gdel, Escher, Bach.[1] BlooP is a non-Turing-complete programming language whose main control flow structure is a bounded loop (i.e. recursion is not permitted). All programs in the language must terminate, and this language can only express primitive recursive functions.[2] wiki.

72: Boo

Boo is an object-oriented, statically typed, general-purpose programming language that seeks to make use of the Common Language Infrastructure's support for Unicode, internationalization, and web applications, while using a Python-inspired syntax[2] and a special focus on language and compiler extensibility. Some features of note include type inference, generators, multimethods, optional duck typing, macros, true closures, currying, and first-class functions. wiki.

73: Boomerang

Boomerang is a programming language for writing lenseswell-behaved bidirectional transformations that operate on ad-hoc, textual data formats. wiki.

A version is also available for Windows 10.[10] wiki.

76: ksh

KornShell (ksh) is a Unix shell which was developed by David Korn at Bell Labs in the early 1980s and announced at USENIX on July 14, 1983.[1][2] The initial development was based on Bourne shell source code.[7] Other early contributors were Bell Labs developers Mike Veach and Pat Sullivan, who wrote the Emacs and vi-style line editing modes' code, respectively.[8] KornShell is backward-compatible with the Bourne shell and includes many features of the C shell, inspired by the requests of Bell Labs users. wiki.

77: BPEL

The Web Services Business Process Execution Language (WS-BPEL), commonly known as BPEL (Business Process Execution Language), is an OASIS[1] standard executable language for specifying actions within business processes with web services. Processes in BPEL export and import information by using web service interfaces exclusively. wiki.

78: Business Basic

Business Basic is a category of variants of the BASIC computer programming language which were specialised for business use on minicomputers in the 1970s and 1980s. Business Basics added indexed file access methods to the normal set of BASIC commands, and were optimised for other input/output access, especially display terminal control. The two major families of Business Basic are MAI Basic Four and Data General Business Basic. In addition the Point 4 company, which developed the IRIS operating system, had their own version of BASIC. The UniBASIC owned by Dynamic Concepts of Irvine is a derivative of the Point 4 BASIC. wiki.

79: C

C (/si/, as in the letter c) is a general-purpose, imperative computer programming language, supporting structured programming, lexical variable scope and recursion, while a static type system prevents many unintended operations. By design, C provides constructs that map efficiently to typical machine instructions, and therefore it has found lasting use in applications that had formerly been coded in assembly language, including operating systems, as well as various application software for computers ranging from supercomputers to embedded systems. wiki.

80: C--

C-- (pronounced cee minus minus) is a C-like programming language. Its creators, functional programming researchers Simon Peyton Jones and Norman Ramsey, designed it to be generated mainly by compilers for very high-level languages rather than written by human programmers. Unlike many other intermediate languages, its representation is plain ASCII text, not bytecode or another binary format. wiki.
