OpenAPL is an open-source APL (A Programming Language) implementation. APL's strength is in the ease with which a programmer can manipulate arrays of numbers or characters.

A+ programming language. APL, scripting, X11, Unix, math, array processing, cool fonts.

This collection of APL libraries have been contributed to GNU APL and should be downloaded here: https://gnu.org/software/apl.

Cotrugli is an experimental accounting application written in GNU-APL that uses PostgreSQL to manage its database. At this writing, Seventh Month 2021, it will create a trial balance and allow one to adjust that that trial balance using an application program interface (API). Users well versed in GNU-APL can enter and adjust that trial balance by using the API. There is much work to be done and I am looking for volunteers.

This program in APL calculates preceding generations for a given generation in Conway's Game of Life. They are small, 4x4 to 13x13 and there are periodic boundary conditions which eliminates many configurations. The APL interpreter that is required to run the program is available as a free demo version.

Is a very flexible dynamic website engine for group of people as well as single person, capable of building sites from several pages to several thousand. It is based on PHP and MySQL.

This is a plugin to write Jsp page with eclipse. It will permit code completion, taglib integration, html, wysiwyg, ....

The OS561 operating system based around FORTH/Java. The OS is to run on a VHDL chip OpenHardware design called the Minon, but could become available for other platforms. The unique point of the design is a revolutionary data compression technology.

A Perl based interpreter for a language which is a blend of Forth and APL. The power of lang5 stems from its arrays operations in conjunction with the underlying Forth programming paradigm of bottom up programming.

APL is an arrary-oriented language initially conceived in the 1960s by Kenneth E. Iverson, IBM Fellow and 1979 ACM Turing Award recipient. It is ideally suited to computer programming because it subsumes the tedious aspects of the job allowing the programmer to concentrate on the heart of the project. NARS2000 is a Free Open Source implementation of APL. For more details on this project, visit the NARS2000.org website.
