A linear history semantics for distributed languages extended abstract

A denotational semantics is given for a distributed language based on communication (CSP). The semantics uses linear sequences of communications to record computations; for any well formed program segment the semantics is a relation between attainable states and the communication sequences needed to attain these states. In binding two or more processes we match and merge the communication sequences assumed by each process to obtain a sequence and State of the combined process. The approach taken here is distinguished by relatively simple semantic domains and ordering.
