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 Kenneth E. Iverson.

It is distinguished by

extreme terseness
defining its primitives over arrays
the use of special glyphs to denote its primitive functions
extensive use of higher-order functions

The original APL\1130 spawned many APLs and related languages. It has also exercised a strong influence on functional_Programming.
