[texhax] MakeUppercase with savebox

[João Oliveira]

Hi,

I am having some trouble on doing the following. I would like to make  
command that defines a save box that flushes the text right and make  
it uppercase. I also would like it to accept new lines, so that I  
could issue something like:

\name{This is\\ an example}
\usebox{\mybox}

and it would produce:

             THIS IS
AN EXAMPLE

(it is supposed to be aligned in the right).

I have use the following definitions:

\newcommand{\name}[1]{\mycommand{#1}}

\newsavebox{\mybox}

\newcommand{\mycommand}[1]{%
\savebox{\mybox}{
	\begin{minipage}{10cm}\begin{flushright} \MakeUppercase{#1}\end 
{flushright}
	\end{minipage}
}}

Why can't I use this with linebreaks? Without them it works... or  
without MakeUppercase I can have the line breaks...
Can anyone have any clue?

Best regards,
João
