= About APL =

APL is A Programming Language, derived from a mathematical notation developed at Harvard in the 1950s and published in a book of the same name by [[WikiPedia:Kenneth_E._Iverson | Kenneth E. Iverson]].

It is distinguished by
 * extreme terseness
 * defining its primitives over arrays
 * the use of [[SpecialCharacters|special glyphs]] to denote its primitive functions 
 * extensive use of higher-order functions 

The original APL\1130 spawned [[/AplsAndRelatedLanguages|many APLs and related languages]]. It has also exercised a strong influence on WikiPedia:functional_Programming.
