Chris Thomson and Colin Broughton founded Chion Corporation which developed and marketed FLACC (Full Language Algol 68 Checkout Compiler). This compiler and run-time system conformed exactly to the Revised Report, ran on IBM 370 and compatible mainframes, and included debugging features derived from WATFIV. It was released in 1977.
Chris was a student of Barry J. Mailloux. Barry studied at Amsterdam's Mathematisch Centrum from 1966 under Adriaan van Wijngaarden. Barry's work on the Algol 68 language established the University of Alberta as a center for Algol 68-related activity.
According to Thomson decade later:
- You know, we only ever got 22 copies installed, and less than 5 of those in North America. Even though it ran on 370's under MVS, CMS and MTS, and was cheap and reliable. Talk about a marketing disaster.
