ALGOL 68-R was the first implementation of the Algorithmic language ALGOL 68. In December 1968 the report on the Algorithmic language ALGOL 68 was published. On 20–24 July 1970 a working conference was arranged by the IFIP to discuss the problems of implementation of the language, a small team from the Royal Radar Establishment attended to present their compiler, written by I.F. Currie, Susan G. Bond〔 〕 and J.D. Morrison. In the face of estimates of up to 100 man-years to implement the language, using up to 7 pass compilers they described how they had already implemented a one-pass compiler which was in production use in engineering and scientific applications. == 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. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「ALGOL 68-R」の詳細全文を読む スポンサード リンク
