I'm trying to ref a label using \ref and output an alphabetical letter (e.g. 'A') rather than the number (e.g. 1).

I have read somewhere to use \AAAlphanum{\ref{my_label}} but this command fails

Missing number, treated as zero.

Any help is greatly appreciated.

    Welcome to TeX.SX! Please help us to help you and add a minimal working example (MWE) that illustrates your problem. It will be much easier for us to reproduce your situation and find out what the issue is when we see compilable code, starting with \documentclass{...} and ending with \end{document}.

There are a number of ways you can achieve this:

enter image description here



\setlength{\parindent}{0pt}% Just for this example


\section{A section}\label{sec:mysection}\mylabel{sec:mysection}
Section~\ref{sec:mysection}. \par
Section~\AlphAlph{\getrefnumber{sec:mysection}}. \par


The first reference uses \ref, which defaults to whatever the \the<counter> is set to (in this case, \arabic{section}). The second reference uses the expandable \getrefnumber provided by refcount. The last reference uses a custom property list (with the aid of zref) to only store and/or retrieve the \AlphAlph-version of the section counter.

All of the above can be extended to use hyperref, of course.
