Genus: Pascals
Sammet category: Multi-purpose

(named for the English philosopher William of Occam (1300-1349))

Now known as "occam 1".


David May et al, 1982. a language which facilitates writing parallel programs, allowing the programmer to specify whether processes are to be executed sequentially or in parallel. Based on CSP and EPL. Designed for the INMOS transputer and vice versa. Expressions are processes, which may be combined in serial and parallel. Processes communicate via named unidirectional channels. There is no operator precedence. It was originally developed for the Inmos Transputer at the Oxford University Computing Laboratory.
