Dyalog APL: Difference between revisions

Revision as of 15:56, 11 November 2019

Dyalog APL was first released by British company Dyadic Systems Ltd. (later Dyalog Ltd.) in 1983 for the Zylog Z80 processor. The name Dyalog is a portmanteau of Dyadic and Zylog. As of 2018, Dyalog APL is available for AIX, Linux (including on the Raspberry Pi), macOS and Microsoft Windows platforms. While mainly based is based on APL2, it adds support for both object-oriented, functional, and tacit programming. Dyalog APL also serves as the inspiration for many hobby implementations of APL.

In 1995, two of the development team — John Scholes and Peter Donnelly — were awarded the Iverson Award for their work on the interpreter. Gitte Christensen and Morten Kromberg were joint recipients of the Iverson Award in 2016.

Dyalog APL is unique among commercial APLs in continuously getting additional primitives and constructs since its initial release
