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 wiki: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 wiki:WikiPedia/functional_Programming.
