Operational semantics: This means giving a compiler or interpreter for the language. The semantics of the language are implicitly defined by the behavior of the compiled/interpreted code.

This is the same as the language introduced in class. Its abstract syntax is: P ::= S. S ::= I = E | S 1;S 2 | if B then S 1 else S 2 end | while B do S end. E ::= N | I | E 1 + E 2 | E 1 – E 2

In operational semantics, programming language constructs are translated into simpler programming language constructs, which become the basis of the meaning of the construct. In denotational semantics, programming language constructs are mapped to mathematical objects, either sets or, more often, functions. However,

does this mean in the context of operational semantics? The answer will be used again in denotational semantics: what a command does is two really two things. First, it has a side a effect; it changes program state. In Operational terms, it changes the store function. So the basic. i.e. while B do C end is (if B is true) C;while B do C end.

Operational Semantics. Operational semantics is the other end of the spectrum, concerned with the rules by which the state of a computer changes. Whereas denotational semantics is inspired by Church and the lambda calculus, operational semantics is inspired by Turing and his machines.
