Categorical list of programming languagesThis is a list of programming language grouped by category. See also
- Assembly languages directly correspond to a machine language (see below) in order to allow machine code instructions to be written in a form understandable by humans. Assembly languages allow programmers to use symbolic addresses which are later converted to absolute addresses by the assembler. Most assemblers also allow for macros and symbolic constants as well.
- SSK (Sistema Simvolicheskogo Kodirovaniya, or "System of symbolic coding") for Minsk family of computers.
- AKI (AvtoKod Ingenera, i.e., "engineer's autocode") for Minsk family of computers was half-step away from assembly languages and doesn't really fit into any other categories in this article.
- Authoring languages
- CLI languages (batch languages)
- sh (the (Stephen) Bourne shell from AT&T)
- bash the b(ourne)a(gain)sh(ell) from Gnu/FSF)
- CLIST (MVS Command List)
- csh (C-like syntax shell from Bill Joy at UC Berkeley)
- EXEC
- EXEC2
- JCL
- ksh (the David K(orn)sh(ell) from AT&T)
- REXX
- Compiled languagess
- BASIC (some dialects, including the first version of Dartmouth BASIC)
- C++ (some implementations)
- Delphi (Borland's Object Pascal development system)
- Java (originally from Sun Microsystems)
- Perl (invented by Larry Wall; usually interpreted)
- Visual Basic (from Microsoft)
- FORTRAN (the first high level, compiled, language -- from IBM, John Backus, et al)
- Scheme (some implementations, i.e. Bigloo)
- Lisp (some implementations)
- COBOL (designed to be so simple even supervisors could follow it -- a US DoD inspired development)
- Algol (extremely influential language design. The second high level language compiler.)
- Curly-brace languagess are languages whose syntax defines statement blocks using curly-brace characters { and }. All are descended from or strongly influenced by C. Examples of curly-brace languages include:
- C (dev ca 1970 by D Ritchie & K Thompson at Bell Labs -- closely associated with the Unix operating system)
- C++
- C# (the C for the .NET project)
- ECMAScript (aka, JavaScript)
- Java
- Perl
- Coyote (a version of C intended to make some common programming errors much harder -- eg buffer overflow)
- D (a step beyond C from Walter Bright, compiler producer extraordinary)
- Pike (another step beyond C)
- PHP
- Dataflow languages rely on a (usually visual) representation of the flow of data to specify the program. Frequently used for reacting to discrete events or for processing streams of data. Examples of dataflow languages include:
- Data-oriented languages provide powerful ways of searching and manipulating the relations that have been described as entity relationship tables which map one set of things into other sets. Examples of data-oriented languages include:
- dBase a relational database access language
- SQL
- M (an ANSI standard general purpose language with specializations for database work.)
- Data-structured languages are languages whose logic is structured in a way similar to their data. These languages are generally well suited to reflection and introspection. Examples of data-structured languages include:
- Lisp, and descendants like Scheme and Tcl. Also TRAC. All use lists as their organizing principle
- FORTH, Poplog and PostScript (all conceptually based on an open stack model for their operations)
- APL (in which data and code alike are stored and operated on as arrays. By Kenneth Iverson)
- It may be argued that assembly languages which statically link data inline with instructions can be considered in this class, albeit in the most primitive way.
- In JOY lists are just a special case of quoted programs.
- Extension languagess
- Functional languagess define programs and subroutines as mathematical functions. Many so-called functional languages are "impure" and also contain imperative features. Examples of functional languages include:
- Interpreted languagess
- BASIC (some dialects)
- C++ (some, esp early, implementations)
- Perl (most implementations)
- VBScript
- LISP (a very early language based (mostly) on Churche's lamba calculus -- By John McCarthy et al at MIT)
- Most scripting languages (below)
- Syntax handling languagess
- Gnu Bison (the FSF's version of Yacc)
- Lex (Lexical analysis -- from Bell Labs)
- Gnu FLEX (the FSF's version of Lex)
- M4
- Yacc (yet another compiler compiler -- from Bell Labs)
- Little languages, which serve a specialized problem domain
- SQL has only a few keywords, and not all the constructs needed for a full programming language
- Awk can serve as a prototyping language for C, because the syntax is similar
- Logical languagess specify a set of attributes that a solution should have rather then a set of steps to obtain such a solution. Examples of logical languages include:
- Prolog which formulates data and the program evaluation mechanism as a special form of mathematical logic known as Horn logic and a general proving mechanism called logical resolution
- Mercury which is based on Prolog
- Machine languages are directly executable by the computer's CPU. It is typically formulated as bit patterns, usually represented in octal or hexadecimal. Each group of npatterns (often 1 or more bytes) caused the circuits in the CPU to execute one of the fundamental operations of the hardware. The activation of specific electrical inputs (eg, CPU package pins for microprocessors), and logical settings for CPU state values, control the processor's computation. Individual machine languages are processor specific and are not portable; they are (essentially) always defined by the CPU developer, not by 3rd parties. The symbolic version, the processor's assembly language, is also -- in most cases -- defined by the developer. Since processors come in families which are based on a shared architecture, the same basic assembly language style can often be used for more than one CPU. Each of the following CPUs served as the basis for a family of processors:
- Procedural languagess are based upon the concept of the unit and scope (the data viewing range of an executable code statement). A procedural program is composed of one or more units or modules--either user coded or provided in a code library; each module is composed of one or more procedures, also called a function, routine, subroutine, or method, depending on the programming language. Examples of procedural languages include:
- Ada (developed as a result of a DoD initiative to define a standard programming language)
- BASIC (BASICs are innocent of most modularity in (especially) versions prior to about 1990)
- C
- C++ (C with objects + much else)
- C# (from Microsoft, essentially an attempt at an improved C)
- CFM
- COBOL
- Component Pascal (an Oberon-2 variant)
- Delphi
- ECMAScript (JavaScript)
- FORTRAN (better modularity in later Standards)
- Java
- Modula-2 (fundamentally based on modules)
- Oberon (improved, smaller, faster, safer follow-on for Modula-2)
- M (more modular in its first release than a language of the time should have been; the standard has become still more modular since then)
- Pascal (successor to Algol60 and predecessor of Modula-2)
- Perl
- PL/C
- PL/1 (large general purpose language, originally for IBM mainframes)
- Rapira
- VBScript
- Visual Basic
- Object-oriented languagess are languages that support 'data & method' objects. The data structures are defined in object classes, which also include executable code (methods). Thus the effects of a change to the code remain localized. Object classes can be extended by inheritance in most of these languages. Examples of object-oriented languages include:
- Ada 95
- C++
- C#
- Common Lisp
- Delphi
- ECMAScript (aka JavaScript -- originally from Netscape)
- Eiffel
- Java (closely related to C++, but with garbage collection, removal of unsafe features, compilation to universally runnable 'bytecode', protective sandbox for security -- originally from Sun Micro)
- Modula-2|modula-3 (data abstraction, information hiding, strong typing, full modularity -- from N Wirth)
- Modula-3 (added more object oriented features to Modula-2)
- NewtonScript
- Oberon(full object orientation equivalence in an original, strongly typed, Wirthian manner)
- Objective C
- Perl 5
- PHP
- PowerBuilder
- Python (object oriented interpretive language)
- Ruby
- Sather
- Self
- Simula (the first object oriented language -- from Norway)
- Smalltalk (full bore object orientation -- from Xerox PARC)
- VBScript (Microsoft Office 'macro scripting' language)
- Visual Basic
- Prototype-based languagess are a special type of object-oriented programming languages, where the distinction between classes and instances have been removed. Examples of prototype-based languages include:
- Rule-based languages instantiate rules when activated by conditions in a set of data. Of all possible activations, some set will be selected and the statements belonging to those rules will be executed. Examples of rule-based languages include:
- Scripting languages: This term has two apparently diffirent, but in fact similar meanings.
In traditional sense, scripting languages are designed to automate frequently used tasks that usually involve calling or passing commands to external programs.
Many complex aplication programs allow users to implement custom functions by providing them with built-in languages. Those which are ofinterpretive type, are often called scripting languages.
More recently many of these applications have chosen to "build in" traditional scripting languages, such as Perl or Visual BASIC, but there are quite a few "native" scripting languages still in use.
- Macro languages embed small pieces of executable code inside a piece of free-form text.
- M4 (originally from AT&T, bundled with Unix)
- C Preprocessor
- PHP
- Stage 2
- Scripting languages such as Tcl and ECMAScript (Javascript) have been embedded into applications so that they behave like macro languages.
- Turing tarpits
- XML-based languagess are languages based on or that operate on XML. Although the big-boy equivalents of oracle/postgresql/mssql don't yet exist for XML, there are languages to navigate through it and its more tree-oriented structure:
- Concurrent languages are those that define commands as messages to a process. Processes are collections of message passes. Generally based on the Pi-Calculus, these have had no commercial success.
- Fourth generation languagess refer to high-level languages built around database systems. They are generally used in commercial environments.

Magnetic Structure On Sun Is Responsible For Powerful Solar Storms
New research links a particular magnetic structure on the Sun with the genesis of powerful solar storms that can buffet Earth's atmosphere. The research may enable scientists to create more accurate computer models of the solar storms, known as coronal mass ejections (CMEs), and could eventually point the way to forecasting the storms days before they occur. Medical Students Respond Positively To Simulated Patient Experience
When a vomiting, simulated patient mannequin was rolled into the lecture hall last fall to teach large numbers of first- and second-year Wake Forest University School of Medicine students about the brain and nervous system, researchers weren't sure what to expect. Saturn Gives Up Its Icy Secrets

Mississippi State University researchers are using a $1.5 million federal grant to implement an innovative oil recovery process that could streamline U.S. production and help reduce the nation's dependence on foreign energy sources. Carnivorous Dinosaur Tracks Discovered In Australia
The first fossil tracks belonging to large, carnivorous dinosaurs have been discovered in Victoria, Australia, by paleontologists. The tracks are especially significant for showing that large dinosaurs were living in a polar environment during the Cretaceous Period, when Australia was still joined to Antarctica and close to the South Pole. Obesity Is Risk Factor For Aggressive Prostate Cancer
Obesity appears to increase the risk of prostate cancer, particularly aggressive disease, and may make it harder to find, researchers say. Smaller prostates also increase the risk of aggressive disease, they say. The Encyclopedia of Diderot &d'Alembert: Collaborative Translation Pro

The Notch pathway is an important molecular signaling mechanism whose existence has been known, or at least hinted at, for nearly a century since the identification of a mutant strain of Drosophila fruit flies with "notched"wings in Thomas Hunt Morgan's lab in 1910.Notch is activated by a protease that is present ubiquitously in the cell membrane. What has long remained a mystery, however, is the question of how Notch receptors that have not been activated by a ligand are protected from digestion by that protease.
