Hi there,
 Hi there,
 I am typesetting code using minted or listings package. It works fine. Now I am hoping to add a label, similar to equation label, on the left side of the code block, looks like following. (%o1) is the label.
 (%o1)  code here here here
        code here here
        code here
        code
 However, I can't find a way to do this. Any hint will be appreciated.

I would think the simplest is to put the code listing in a list item, eg
\usepackage{enumitem,listings}
...
\begin{enumerate}[label={(\%ol)}]
\item \begin{lstlisting}
foo
bar
\end{lstlisting}
\end{enumerate}
That way (enumitem) you have good control over the label and the spacing.
