No; the \uppercase has to be outside the \csname, as follows:

	  \expandafter\gdef\csname x\thisupper\endcsname
		{\noindent\hbox to\wdx{(\hfil#1\hfil)}}%

The extra \bgroup...\egroup is to contain any extra local
definitions or counter settings (such as \thisupper here)
to within that group. The \gdef forces \xA to become global.

Hope this helps,
