What is Algol 68 Genie?

Algol 68 Genie (a68g) is a well-featured Algol 68 interpreter. It can be used for executing Algol 68 programs or scripts. Algol 68 is a rather lean orthogonal general-purpose language that is a beautiful means for denoting algorithms. Algol 68 was designed as a general-purpose programming language by IFIP Working Group 2.1 (Algorithmic Languages and Calculi) that has continuing responsibility for Algol 60 and Algol 68.

Since Algol 68 Genie became available, it has become clear that there still are many people who are interested in an Algol 68 implementation, the majority of them being mathematicians or computer scientists. The language is nowadays still referred to in teaching material, discussions and publications. Because of the exceptional rigour and precision of its definition, one could argue that those interested in the design and formal specification of programming languages should at an appropriate moment study Algol 68, irrespective of whether the language did or did not spread widely at the time it was presented.

For programmers, the world has of course moved on, but the reactions on Algol 68 Genie indicate that many people who have seriously programmed in Algol 68 in the past, only moved to other programming languages because the Algol 68 implementations they were using were phased out. The Algol 68 Genie project preserves Algol 68, both by making available its defining document as well as an implementation, hence those interested in the language can both study it, and use it.
