\section{Execution Files} \label{exec:files}

The table below summarizes the files used by \numbers.

\begin{center} \begin{tabular}{||l|c|c|c||}
\hline
\multicolumn{1}{||c}{Description} &
\multicolumn{1}{|c}{Unit Number} &
\multicolumn{1}{|c}{Type} &
\multicolumn{1}{|c||}{File Format} \\
\hline
     User input & standard input  & input  & Section~\ref{c:commands} \\
    User output & standard output & output & ASCII \\
Output file     &               7 & output & ASCII \\
EXODUS database &               9 & input  & \\
\hline
\end{tabular} \end{center}

All files must be connected to the appropriate unit before
\numbers\ is run. Each file (except standard input and output) is
opened with the name retrieved by the \caps{EXNAME} routine of the
\caps{SUPES} library \cite{supes}.
