Tuesday 3 December 2024 17:57 UTC Welcome To The NARS2000 Project

Welcome to NARS2000 Wiki where Nested Arrays-APL-APL2, how they work and what they do - abundantly awaits you, as a learning tool and later as a great reference and refresher! This wiki also proposes to create an on-line reference for the APL Programming Language (this is a link to the article on Wikipedia) as implemented by NARS2000.

Useful NARS links: NARS2000 home page, NARS news. Sudley Place APL Projects.
NARS2000 Download and NARS2000 Source Code at SourceForge.net.
ACM Special Interest Group - SIG APL including APL News generally.
