  Martin Giese <giese at ira.uka.de> recently report a problem in `pst-char' when
the \pscharpath macro is used inside another one (in fact I found this problem
because he send to me an example he used with PST 0.93 which didn't work for
me...).

  Correction was easy when I have understood the problem.

  Thanks for the report!

  * 98/07/03 pst-grad.tex (97 patch 1): In the \pscharpath macro, the
PostScript code is not reset after it inclusion, which cause problem when
this macro is used inside another one.
(reported by Martin Giese <giese at ira.uka.de>)

  My test case is:

\documentclass{article}

\usepackage{pst-grad}
\usepackage{pst-char}

\makeatletter

\def\pscharpath at ii{%
  \leavevmode\hbox{%
    \pstVerb{\tx at CharPathShow}%
    \box\pst at hbox
    \pstVerb{/show /tx at CharPathSavedShow load def}%
    \begin at ClosedObj
      \def\pst at linetype{1}%
      \psdashadjustfalse
      \showpointsfalse
      \let\pst at newpath\@empty
      \def\use at pscode{%
        \pst at Verb{%
          gsave
            \tx at STV
            \pst at code
          grestore
% DG/SR modification begin - Jul.  3, 1998 - Patch 1
%          \if at star\else CP newpath moveto \fi}}%
          \if at star\else CP newpath moveto \fi}
        \gdef\pst at code{}}%
% DG/SR modification end
    \end at ClosedObj}}

\makeatother

\pagestyle{empty}

\begin{document}

\psframebox[fillstyle=gradient]{%
  \DeclareFixedFont{\RmLarge}{T1}{ptm}{m}{n}{3cm}
  \pscharpath[linestyle=none,fillstyle=gradient,gradend=red]{\RmLarge Test}}

\end{document}
