Abstract

The Denotational Semantics of a small programming language is coded into Algol-68 to give an interpreter. The Semantics incorporates many of the notions of Standard Semantics including declarations, declaration continuations, final answers and stores or memory which are used to define block structuring, output and parameterless procedures. This extends work previously reported1. The coding in Algol-68 is quite straightforward and the result is a type checked and executable semantics which is as readable as the original semantics to one familiar with Algol-68. No special software is needed other than a compiler for the general purpose language Algol-68.
