Abstract. We describe the construction and use of a system for trans­
lating higher order logic­based specifications into programs in the higher
order logic programming language Lambda Prolog. The translation im­
proves on previous work in the field of executing specifications by allow­
ing formulas with quantifiers to be executed, and by permitting users
to pose Prolog­style queries with free variables to be instantiated by the
system. We also discuss various alternative target languages and design
decisions in implementing the translator.
1 Introduction
One of the early goals of formal specification in software engineering
was to provide a formal model against which an implementation of
the software, or a more detailed model, could be checked. This goal
has not been fully realized in practice. But even where no tools exist
to check an implementation against a specification, the process of
