Tabbing and auto-numbering

[Hasan Qunoo]

Dear All,

I am using Tabbing to write a number of C like programs. I want to
number these lines either on the left side as usual or one the right
side as a comment. I am also referring to these numbers in the text. I
can do that manually but it involves a lot of updates per change.

I tried using  \ref and \label but they refer to the section number. I
know that I can use equations or enumerates to reset the numbering but
will have issues with alignment and style. I also found some people
advocating amsmath and mathenv. However, using these two packages
results in a lot of modifications that I would like to avoid.

Please advice,

Thanks in advance.

Hasan,

Use the listings package, since it is designed specifically for your
requirements - line numbers, indentation, referencing, comments, etc.
It is available online via CTAN from:
http://tug.ctan.org/cgi-bin/ctanPackageInformation.py?id=listings
Browse the package documentation to get an idea of the capabilities of
the package.

Thanks a lot,

I can not use listings as it does not accept math. Any other ideas?

Hasan,

This is not true. Listings is set up to accept math, although this is
not the default case, since programming languages have different
control mechanisms and operators. If you're interested in using
LaTeX's math mode inside a listing environment, use the mathescape
option:

\begin{lstlisting}
// \upshape calculate $a_{ij}$
$A[i][j]$ = A[j][j]/A[i][j];
\end{lstlisting}

versus

\begin{lstlisting}[texcl]
// \upshape calculate $a_{ij}$
A[i][j] = A[j][j]/A[i][j];
\end{lstlisting}

versus

\begin{lstlisting}[mathescape]
// calculate $a_{ij}$
$a_{ij} = a_{jj}/a_{ij}$;
\end{lstlisting}

Additionally, the mathescape options allows the addition of (almost?)
anything (La)TeX-like... even including graphics. See p 54 of the
documentation for an example.

Use \refstepcounter instead of \stepcounter for the automatic
numbering. Each tabbing item is in a local group, so you must
put the \label after \refstepcounter in the same item.

But also check if existing packages can do what you need.
