ACL2 ( A Computational Logic for Applicative Common Lisp ) is a software system consisting of a programming language, an extensible theory in a first-order logic, and a mechanical theorem prover.

* ACL2 – a programming language, a first-order logical theory, and a theorem prover ( with both interactive and automatic modes ) in the Boyer – Moore tradition.

The input language and implementation of ACL2 are built on Common Lisp.

The theorem provers Isabelle and ACL2 adopt this methodology by providing a language for conservative extensions by definition.

Not yet fully ANSI-compliant, GCL is however the implementation of choice for several large projects including the mathematical tools Maxima, AXIOM and ( historically ) ACL2.

ACL2 is designed to support automated reasoning in inductive logical theories, mostly for the purpose of software and hardware verification.

ACL2 is free, open source ( GPL ) software.

ACL2 is untyped.

All ACL2 functions are total — that is, every function maps each object in the ACL2 universe to another object in its universe.

ACL2 is intended to be an " industrial strength " version of the Boyer – Moore theorem prover, NQTHM.

ACL2 also derives efficiency from being built on Common Lisp ; for example, the same specification that is the basis for inductive verification can be compiled and run natively.

In addition, Moore is a co-author of the ACL2 automated theorem prover.

* ACL2, a full-featured automated theorem prover for an applicative variant of Common Lisp.

Toward this goal, ACL2 has many features to support clean engineering of interesting mathematical and computational theories.

In 2005, the authors of the Boyer-Moore family of provers, which includes ACL2, received the ACM Software System Award " for pioneering and engineering a most effective theorem prover (...) as a formal methods tool for verifying safety-critical hardware and software.

ACL2 has been used on numerous applications.

For example, J Strother Moore and Matt Kaufmann used ACL2 to prove the correctness of the floating point division operations of the AMD K5 microprocessor in the wake of the Pentium FDIV bug.

* ACL2s-ACL2 Sedan-An Eclipse-based interface developed by Peter Dillinger and Pete Manolios that includes powerful features to provide users with more automation and support for specifying conjectures and proving theorems with ACL2.

It consists of using a formal version of mathematical reasoning about the system, usually using theorem proving software such as a HOL theorem prover, the ACL2, Isabelle, or Coq theorem provers.

He and others used ACL2 to prove the correctness of the floating point division operations of the AMD K5 microprocessor in the wake of the Pentium FDIV bug.

* Ada ( programming language ), programming language based on Pascal

** Atlas Autocode, a programming language developed for the Atlas Computer

* ATLAS, Abbreviated Test Language for All Systems, a programming language used for automated test equipment

* APL ( programming language ), a computer programming language with specialized array-processing capabilities

An applet typically also refers to Java applets, i. e., programs written in the Java programming language that are included in a web page.

The programming language to be employed by users was akin to modern day assembly languages.

The modern computer programming language Ada is named in her honour.

The computer was brought to Polytechnic University of Turin where it was fixed and used to run the BASIC programming language .</ li >

An assembly language is a low-level programming language for a computer, microcontroller, or other programmable device, in which each statement corresponds to a single machine code instruction.

Each assembly language is specific to a particular computer architecture, in contrast to most high-level programming languages, which are generally portable across multiple systems.

* ASIC programming language, a dialect of BASIC

* Address programming language

* Scheme ( programming language )

Such a description language can be based on any computer programming language, such as Lisp, Pascal, or Java Virtual Machine bytecode.

For this reason, the C programming language specifies that array indices always begin at 0 ; and many programmers will call that element " zeroth " rather than " first ".

Much of the AIX v2 kernel was written in the PL / I programming language, which proved troublesome during the migration to AIX v3.

* ABC ( programming language ), an imperative general-purpose programming language and programming environment developed at CWI, Netherlands by Leo Geurts, Lambert Meertens, and Steven Pemberton

Our literature is already replete with a fantastic number of suggestions for preventive agency programming ranging from the immediately practical to the globally utopian.

At the same time, every device that can be employed to reduce the number of variables is of the greatest value, and it is one of the attractive features of dynamic programming that room is left for ingenuity in using the special features of the problem to this end.

The set of equations ( 5 ), ( 6 ), and the starting equation ( 7 ) is of a recursive type well suited to programming on the digital computer.

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.

The purpose of RHA is to enhance the quality of residence hall life and provide a cohesive voice for the residents by addressing the concerns of the on-campus populations to university administrators and other campus organizations ; providing cultural, diversity, educational, and social programming ; establishing and working with individual hall councils.

The term array is often used to mean array data type, a kind of data type provided by most high-level programming languages that consists of a collection of values or variables that can be selected by one or more indices computed at run-time.

In computer science, an abstract data type ( ADT ) is a mathematical model for a certain class of data structures that have similar behavior ; or for certain data types of one or more programming languages that have similar semantics.

The notion of abstract data types is related to the concept of data abstraction, important in object-oriented programming and design by contract methodologies for software development.

In the " imperative " view, which is closer to the philosophy of imperative programming languages, an abstract data structure is conceived as an entity that is mutable — meaning that it may be in different states at different times.

As in so many programming languages, the operation ( V, x ) is often written V ← x ( or some similar notation ), and ( V ) is implied whenever a variable V is used in a context where a value is required.

This advanced programming technique is documented in the original 1983 " Atari 3600 Software Guide ".

AMOS BASIC is a dialect of the BASIC programming language implemented on the Amiga computer.

" C11 " is the new standard for the C programming language.

The byte is also defined as a data type in certain programming languages.

The situation is complex, however, because the relatively free Russian media is allowed to transmit television programming, sell newspapers and conduct journalistic activities in Belarus ( though some Russian journalists have been expelled by the Belarusian government ) thus giving some members of the public, typically those in large cities with many Russian residents, access to an alternative point of view in the Russian language ( nearly all Belarusians understand and most of them speak Russian ).
