\title{Data refinement of representation of a file}
\author{Karen Zee and Viktor Kuncak}
\maketitle

\begin{abstract}
  This document illustrates the verification of basic file
  operations (file creation, file read and file write) in
  Isabelle theorem prover \cite{LNCS2283}.  We describe a
  file at two levels of abstraction: an abstract file
  represented as a resizable array, and a concrete file
  represented using data blocks.
