ALGOL 68C

The language was originally called Z70 and was subsequently morphed into ALGOL 68. ALGOL68C was initially built to develop and program the CAMbridge ALgebra system a.k.a. CAMAL. The initial compiler was written in PSYCO (the Princeton SYntax COmpiler by Edgar T. Irons) that was implemented by J.H. Mathewman at Cambridge. The compiler and language were initially developed by Stephen Bourne and Michael Guy as a dialect of ALGOL 68.
