aw2caw2caw2c is a new compiler for the Algol W language. It is a complete implementation of the language described in the Algol W Language Description, June 1972. aw2c should be able to compile code intended for the OS/360 Algol W compilers with little or no modification. See the aw2c manual for more details.
Algol W is a successor to Algol 60 closely based on A Contribution to the Development of ALGOL by Niklaus Wirth and C. A. R. Hoare. It includes dynamically allocated records, string handling, complex numbers and a standard I/O system. A copy of the Algol W Language Description can be found on Karl Kleine's Historic Documents in Computer Science page. Dabcanboulet's Algol W @ Everything2 page contains an excellent history and tutorial.
aw2c correctly compiles Tony Marsland's computer chess player Awit and Hendrik Boom's A68H Algol 68 compiler.
The main requirements are a Unix environment, Gnu C, Python, OCaml and the Boehm-Demers-Weiser garbage collector. In Debian or Ubuntu "apt-get install gcc ocaml-nox python libgc-dev" is enough. For details read INSTALL.
Tar file: aw2c.tar.gz, for details read INSTALL.

Thank you to: Hendrick Boom, Tony Marsland and Carey Bloodworth for a great deal of expert advice, encouragement and testing; the authors of the Algol W Language Description for creating such an unambiguous work; and Julian Melville, for this web hosting.
If you have found this software useful or enlightening, please consider donating to the Hooting Yard radio show or buying one of Frank Key's books. Frank Key keeps me sane, somehow.
