The J programming language, developed in the early 1990s by Ken Iverson and Roger Hui, is a synthesis of APL (also by Iverson) and the FP and FL function-level languages created by John Backus.
To avoid repeating the APL special character problem, J requires only the basic ASCII character set, resorting to the use of digraphs formed using the dot or colon characters to extend the meaning of the basic characters available. Additionally, to keep parsing and the language simple, and to compensate for the lack of character variation in ASCII, J treats many characters which might need to be balanced in other languages (such as [] {} "" `` or ) as stand alone tokens or (with digraphs) treats them as part of a multi-character token.
Being an array programming language, J is very terse and powerful, and is most suited to mathematical and statistical programming, especially when performing operations on matrices. J is a MIMD language.
Like the original FP/FL languages, J supports function...
