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 [http://www.fh-jena.de/~kleine/history/history.html Historic Documents in Computer Science] page. [http://everything2.com/title/Algol%2520W Dabcanboulet's Algol W @ Everything2] page contains an excellent history and tutorial.
[http://www.jampan.co.nz/~glyn/ aw2c] 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.
aw2c correctly compiles Tony Marsland's computer chess player [http://webdocs.cs.ualberta.ca/~tony/Public/Awit-Wita-ComputerChess/ Awit] and Hendrik Boom's [http://mtn-host.prjek.net/projects/a68h/ A68H] Algol 68 compiler.
