Abstract
Reynolds described the “essence of Algol” as the simple imperative language combined with the typed lambda calculus. We provide a similar description of Wirth's language Oberon as the simple imperative language combined with procedure types and record extension. Whereas the semantics of Algol has been given in terms of a (domain theoretic) model using an explicit representation of storage, our semantics uses predicate transformers; this is possible thanks to recent advances in the theory of predicate transformers. Predicate transformer semantics connects one of the most successful methods of rigorous program development with one of the most successful pragmatically-designed programming languages.
