Categorical Semantics, Or Extending Data Types to Include Memory
This paper extends the algebraic theory of data types so that it can deal with issues, such as those involving memory, that can not be easily treated within the usual algebraic specification framework. The result is a simple, uniform, mathematical framework in which we can treat, not only data types and their operations, but also, the semantics of imperative languages with assignment, conditionals, while-do’s, and elementary exception handling.
