The denotational semantics for programming languages was originally developed by the American logician Dana Scott and the British computer scientist Christopher Strachey. It can be described as an application of the semantics to computer languages that Scott had developed for the logical systems known as lambda calculus. Denotational semantics is a method for precisely defining programming languages.Most descriptions of programming languages today have a formal syntactic definition (ie using BNF).The semantics, however, is usually described in a natural language, which can be rather imprecise. zDenotational Semantics of Loops (continued) 2of 25 Generalizing the solution zParameterize the factorial function zThis means zi.e. F =→λf nnequals zero one ntimes f nminus one.λ.

The most successful system is denotational semantics which describes all the features found in imperative programming languages and has a sound mathematical basis. (There is still active research in type systems and parallel programming.) An important principle of denotational semantics is that the meaning of a program is determined from its text compositionally. This means that the meaning of a program must be de ned from the meanings of its parts, not something else, such as the text of its parts or the meanings of related programs obtained by syntactic operations. For Denotational semantics is a methodology for giving mathematical meaning to programming languages and systems.

It was developed by Christopher StracheyÕs Programming Research Group at Oxford University in the 1960s. The method combines mathematical rigor, due to the work of Dana Scott, with notational elegance, due to Strachey.
