Abstract

The history of ideas that led to the first formalization of the syntax and semantics of PL/I is sketched. The definition method and notation are known as the Vienna Definition Language (VDL). The paper examines the relationship between VDL and both denotational semantics and the axiomatic approach to programming language definition.
