A Programming Language
APL
ISO 8485
(APL) A programming 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.
Dyalog APL/W and Visual APL are recognized .NET languages.
Dyalog APL/W, APLX and APL2000 all offer object-oriented
extensions to the language.
ISO 8485 is the 1989 standard defining the language.
Commercial versions: APL SV, VS APL, Sharp APL, Sharp APL/PC,
APL*PLUS, APL*PLUS/PC, APL*PLUS/PC II, MCM APL, Honeyapple,
DEC APL, <APL+Win, APL+Linux, APL+Unix and VisualAPL>, <Dyalog APL>, <IBM APL2>, <APLX>, <Sharp APL>
Open source version: <NARS2000>.
