APL ==>
A Programming Language definition
<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.
