The Algol 68 Genie project

The development of Algol played an important role in establishing computer science as an academic discipline. The former Mathematisch Centrum Amsterdam, now Centrum voor Wiskunde & Informatica, was a leading institute in the design of Algol 68 , as it was in later years in the development of Python .

The Algol 68 Genie project preserves Algol 68 out of educational as well as scientific-historical interest, by making available a recent implementation written from scratch by Marcel van der Veer, together with extensive documentation for both the language and this new implementation.

Algol 68 Genie is free software distributed under the GNU General Public License; it is a fast compiler-interpreter which ranks among the most complete implementations of the language.

From this site you can download the current version and its documentation. The distribution lets you build Algol 68 Genie from source code on Linux or related operating systems. For Microsoft Windows 10 and 11 a WIN32 executable a68g.exe is provided that must be run using the Windows command line interpreter cmd.exe.

The documentation consists of detailed installation instructions, a comprehensive guide to programming in Algol 68, and the Revised Report on Algol 68.

Alternatively, on this site you can browse the source code.

Please send comments and bug reports to; your feedback will be appreciated.
