CORAL66 programming languageCORAL or Computing Online Realtime Algorithmic Language was developed at the Royal Radar Establishment (RRE), Malvern, UK. The "66" in its name indicates the year (1966) that its definition became formalized.
It bore some similarities to the Algol programming language; having been developed six years later it also embodied some features of Algol 68. All variables in CORAL 66 are required to be typed and defined before use.
It was used to program both Ferranti and GEC computers from 1971 onwards.
