I wish to make the list of authors show up as centered, uppercase and listed vertically on my titlepage. My documentclass contains a section like this
\begin{center}
...
\renewcommand{\and}{\\}\MakeUppercase{\@author}
...
\end{center}
but this particular combination or linebreaks, MakeUppercase and centering causes an error; \@icentercr doesn't match its definition
A minimal example would be
\documentclass{article}
\newcommand{\mytext}{Foo \\ Bar}
\begin{document}
\begin{center}
\MakeUppercase{\mytext}
\end{center}
\end{document}
