[pstricks] A simple file

[Denis Vergès]

Hello

What's wrong in

\documentclass[10pt]{article}
\usepackage{pstricks,pst-plot}
\begin{document}
\psset{xunit=0.8cm,yunit=0.004cm}
\begin{pspicture}(0,0)(15,3000)
\psaxes[linewidth=1.75pt]{->}(0,0)(15,3000)
%\rput(15,-80){$x$} \rput(-0.5,3000){$y$}
\uput[d](1,0){$1$}
\multido{\n=0.0+.1}{151}{\psline(\n,0)(\n,3000)}
\multido{\n=0+100}{31}{\psline(0,\n)(15,\n)}
\psplot{0}{15}{x 3 exp x  2 exp 10 mul  sub 25 x mul add 1200 add}
\uput[u](13,200){$\mathcal{C}$}
\rput(7.5,-500){\textbf{ANNEXE EXERCICE 2 Partie B}}
\end{pspicture}
  \end{document}

In the log file  I have :

! TeX capacity exceeded, sorry [save size=5000]. ???

Thanks.
