The Compiler
The ALGOL 68-R compiler was initially written in a local dialect of ALGOL 60 with extensions for address manipulation and list processing. The parser was written using J.M. Foster's Syntax Improving Device (SID) parser generator.

The first version of the compiler occupied 34K words. It was later rewritten in ALGOL 68-R, taking around 36K words to compile most programs.
ALGOL 68-R was implemented under the GEORGE 3 operating system on an ICL 1907F. The compiler was distributed without charge by ICL on behalf of the RRE.
