Abstract: Full CSP is provided with a truly concurrent distributed operational semantics based on C/E Systems: Given a CSP process Pr, a contact-free C/E System is derived the case graph of which is understood as the operational semantics of Pr. Thus concurrency and causal dependicies among the actions a process can perform are explicitly described.
