\begin{abstract}\noindent
The formalization of the denotational and operational semantics of a simple
while-language together with an equivalence proof between the two semantics.
The whole development essentially formalizes/transcribes chapters 2 and 5 of
\cite{Winskel}. A much extended version of this development is found in
HOL/IMP of the Isabelle distribution.
