This wiki is about the '''APL Programming Language''', one of the oldest (in terms of age) and youngest (in terms of concepts) of all programming languages. It is an interpreted language with built-in array capabilities and outstanding debugging features that makes the language an excellent choice for the [[WikiPedia:Agile_software_development|agile approach]]. APL is also the very first functional programming language ever.

If you are curious about APL consider reading Bernard Legrand's excellent article [[http://www.vector.org.uk/archive/v231/legrand.htm|"APL - a Glimpse of Heaven"]] on [[http://www.vector.org.uk/|Vector]].
