Using the Latex Algorithmic Package for a Switch Statement?

Question

My googling did not come up with how to make a switch statement in an algorithm using an algorithm and algorithmic packages, but I guess you can. Most guides just didn't mention it anyway.

\begin{algorithm}
\caption{send(...) method}
\begin{algorithmic}
\IF{dest equals..}
%\SWITCH{nature}
\STATE cast data...
\STATE extract data...
\STATE copy...
%\ENDSWITCH
\ELSE
\STATE match dest....
%\SWITCH{nature}
\STATE cast data...
\STATE extract data...
\STATE send...
%\ENDSWITCH
\ENDIF
\end{algorithmic}
\end{algorithm}

Thank!
