''APL'' is occasionally re-interpreted to stand for ''Array Programming Language'' or ''Array Processing Language'', thereby making ''APL'' into a [[wikipedia:backronym|backronym]]. | |||
Falkoff coined the name in 1966 during the implementation of [[APL\360]] at [[IBM]].

The letters APL are shared by [[wikipedia:APL|many other entities]].
