A Programming Language
     
         (APL) A language designed originally by Ken Iverson
        at {Harvard University} in 1957-1960 as a notation for the
        concise expression of mathematical {algorithms}.  It went
        unnamed (or just called {Iverson's Language}) and
        unimplemented for many years.  Finally a subset, APL\360, was
        implemented in 1964.
     
        APL is an {interactive} {array-oriented} language and
        programming environment with many innovative features.  It was
        originally written using a non-standard {character set} but
        now can use {ISO8485}.  It is {dynamically typed} with
        {dynamic scope}.  APL introduced several functional forms but
        is not {purely functional}.
     
        {Dyadic Systems} {APL/W} is one of the languages that will be
        available under {Microsoft}'s {.NET} initative.
     
        Versions: APL\360, APL SV, {Dyalog APL}, VS APL, Sharp APL,
        Sharp APL/PC, APL*PLUS, APL*PLUS/PC, APL*PLUS/PC II, MCM APL,
        Honeyapple, DEC APL, Cognos {APL2000
        (http://www.apl2000.com/)}, IBM {APL2}.
     
        See also {Kamin's interpreters}.
     
        {APLWEB} translates {WEB} to {APL}.
     
        {Dijkstra} said that APL was a language designed to perfection
        - in the wrong direction.
