ISO 8485 ==>
A Programming Language
<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.
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.
ISO 8485 is the 1989 standard defining the language.
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, 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.
