A derivative and redesign of APL with added features and
control structures. J is purely functional with lexicalscope and more conventional control structures, plus several
new concepts such as function rank and function arrays. J
was designed and developed by Kennneth E. Iverson and Roger
Hui [email protected]. J uses only the ASCII
character set but has a spelling scheme that retains the
advantages of APL's special alphabet. J is a conventional
procedural programming language but can be used as a purelyfunctional language.
