development of Algol
played an important role in
establishing computer science as an academic discipline.
The Algol 68 Genie project preserves and promotes
out of educational as well as
scientific-historical interest, by making available
a recent checkout compiler-interpreter
written from scratch by
Marcel van der Veer.

Algol 68 Genie
is a fast compiler-interpreter which ranks among the most
complete implementations of the language;
it supports for instance

Recently, the well-known book
Informal Introduction to Algol 68
by C.H. Lindsey and S.G. van der Meulen ,
was made available online.

is a secure, expression-oriented programming language
with which you elegantly code algorithms without
having to bother too much about irrelevant technical details
and limitations inherent to many other languages.
Algol 68 Genie offers for example:
» many runtime checks facilitating debugging and improving the
reliability of your programs,
» native support for arbitrary precision arithmetic including
» syntactic constructions to support linear algebra,
» a gdb-style debugger and a pretty-printer to
beautify source code,
» optional linkage to GNU plotutils,
the GNU scientific library or PostgreSQL,
» extensions as UNIX pipes, regular expression matching,
and web page content fetching.
Current stable release
released in November 2012
lets you build Algol 68 Genie on Linux, FreeBSD,
Mac OS X, Solaris or Cygwin from source code.
Detailed installation instructions are in the book
Learning Algol 68 Genie.
A hyperlinked HTML version of the
is available from these project pages.
For interested developers, the
Algol 68 Genie Technical Reference,
Algol 68 Genie comprises circa 70,000 lines ANSI C code.
The implementation is regression tested with a suite totalling
roughly 300,000 lines Algol 68 code in 1,500+ programs,
the largest program having ± 35,000 lines of code.
The suite includes the well known
Mathematisch Centrum Algol 68 Test Set and
the synthetic Bernard Houssais test set, both available from
Dick Grune's web site
or from the
Vrije Universiteit Amsterdam.
The test suite also includes programs from
Rosetta Code and
For Microsoft Windows XP, Vista or Windows 7, an
algol68g-2.6 WIN32 executable
is available which is linked to GNU plotutils
and the GNU scientific library.
Unzip it and execute it from the Windows command line
Prebuilt binaries have been posted for Linux, Mac OS X,
Cygwin and Arch Linux.
