  Encyclopedia: APL programming language
APL (for A Programming Language, or sometimes Array Processing Language) is an array programming language based on a notation invented in 1957 by Kenneth E. Iverson while at Harvard University.
APL is well-known for its use of a set of non-ASCII symbols that are an extension of traditional arithmetic and algebraic notation.
APL is renowned for using a set of non-ASCII symbols that are an extension of traditional arithmetic and algebraic notation and being able to express an air traffic control system in two lines of code.

 Encyclopedia topic: APL programming language   (Site not responding. Last check: 2007-09-18)
Because APL has so many nonstandard primitives (functions, operators, or features built into the language and indicated by a single symbol or a combination of a few symbols), APL does not have function or operator precedence (additional info and facts about operator precedence).
APL is well-known for its use of a set of non-ASCII ((computer science) a code for information exchange between computers made by different companies; a string of 7 binary digits represents each character; used in most microcomputers) symbols that are an extension of traditional arithmetic and algebraic notation.
APL has perhaps had an unusually high percentage of users who are subject-matter experts who know some APL, rather than professional programmers who know something about a subject.

 FHD.van Batenburg: APL information
APL has many powerful functions that you may not need for every application but that come in handy when you need them (for example matrix inverse, many trigonometric functions and their inverses, sorting, searching and many others).
APL is used over a wide spectrum of applications, varying from prototyping, administration, to science in a great diversity of applications, varying from data mining to mathematical applications such as actuarial use.
This APL has nested arrays, it is fully ISO extended compatible and it has implemented the APL-lish control structures as described previously in APL language proposals.

 Apl Language
APL was developed by KenIverson who has since gone on to direct his attention to the language J [JayLanguage].
APL was once used to prototype SQL - SQL could be looked at as an attempt to extract the data-storage aspects of APL into a form which is generally useful.
In APL, on the other hand, you can use the same code to deal with 1:1, 1:n, n:1, or n:n multiplicities (yes, n:n is really 1:1 multiplicity, but you wouldn't know that by the way you have to represent it in a classic OO language).
