High Quality Content by WIKIPEDIA articles! In computer science, operational semantics is a way to give meaning to computer programs in a mathematically rigorous way. Other approaches to providing a formal semantics of programming languages include axiomatic semantics and denotational semantics.The operational semantics for a programming language describes how a valid program is interpreted as sequences of computational steps. These sequences then are the meaning of the program. In the context of functional programs, the final step in a terminating sequence returns the value of the program. (In general there can be many return values for a single program, because the program could be nondeterministic, and even for a deterministic program there can be many computation sequences since the semantics may not specify exactly what sequence of operations arrives at that value.)
