Who uses J programming language?

The J programming language, developed in the early 1990s by Kenneth E. Iverson and Roger Hui, is an array programming language based primarily on APL (also by Iverson).

Is APL open source?

Kona is an open-source ascii based APL, inspired from K. J7 was recently released under the GPL.

What type of language is APL?

APL (named after the book A Programming Language) is a programming language developed in the 1960s by Kenneth E. Iverson. Its central datatype is the multidimensional array. It uses a large range of special graphic symbols to represent most functions and operators, leading to very concise code.

What does an array allow the programmer do?

An array is a data structure, which can store a fixed-size collection of elements of the same data type. An array is used to store a collection of data, but it is often more useful to think of an array as a collection of variables of the same type.

What is the difference between K and J in APL?

It was a precursor to K. Languages in the array-language family that have departed from the distinctive APL character set include J, K, and Nial. Nial uses English words instead of symbols, and has an open source interpreter called Q’Nial. K and J rely mainly on symbols, but these are drawn from the ASCII character set.

What is APL programming language?

APL is the Classical Chinese of programming languages. Words consisting of several characters in other languages are instead written with a symbol or two. These symbols can be overloaded. Meaning is often inferred. Thus APL and J snippets possess the aesthetic appeal of a classical Chinese poem.

Tacit J is closely related to “point-free” style found in functional programming languages, but differs in that this form is fundamental to the J language. The ASCII-based symbols used in J may be harder to read than the more distinctive APL characters.

What is the difference between APL and Nial?

Languages in the array-language family that have departed from the distinctive APL character set include J, K, and Nial. Nial uses English words instead of symbols, and has an open source interpreter called Q’Nial. K and J rely mainly on symbols, but these are drawn from the ASCII character set.
