Just to point out that you must make sure that the text inside the
verbatim environment does not exceed the defined width.  Here is an
example file.  It defines a new environment called ``boxverbatim''.
It calculates the width by subtracting the space between columns (in
this case, the beginning and ending extra space) and the width of
the rule.  Try it out and see if this helps.

------------------ boxedverb.tex --------------------------
\documentstyle {article}
\newlength{\verbboxwidth}
\setlength{\verbboxwidth}{\textwidth}
\addtolength{\verbboxwidth}{-2\arrayrulewidth}
\addtolength{\verbboxwidth}{-2\tabcolsep}
\newenvironment{boxverbatim}%
   {\begin{flushleft}%
    \begin{tabular}{|l|}\hline%
    \\%
    \begin{minipage}{\verbboxwidth}}%
   {\vspace*{.5\baselineskip}%
    \end{minipage}%
    \\\hline%
    \end{tabular}%
    \end{flushleft}}
\begin{document}
A paragraph before we try to box some verbatim text.  It is quite
easy, especially if you use the tools provided with \LaTeX.

\begin{boxverbatim}
\begin{verbatim}
\begin{description}
\item [Attributive Predicate:] {\em The electron has
      both a mass and a charge.}
\item [Renaming Predicate:] {\em The negative electrode
      is called the cathode.}
\item [Conclusion Predicate:] {\em From the experiment,
      it was concluded that the electron had a charge
      that was negative.}
\end{description}
\begin{equation}
x = y + z
\end{equation}
\end{verbatim}
\end{boxverbatim}
