[pstricks] multido controlled by postscript variables

[Poul Riis]

The following (silly) project works

\documentclass{article}
\usepackage{multido}
\usepackage[x11names]{xcolor}
\usepackage{pst-tools}
\usepackage{pstricks-add}


\begin{document}
\pstVerb{/nxmax 5 def /nymax 4 def}
\psset{linecolor=red}
\begin{psgraph}[arrows=->](0,0)(5,4){5cm}{5cm}
\multido{\ny=1+1}{4}{
	\multido{\nx=1+1}{5}{
		\uput{0pt}[90]{0}(!\nx\space \ny\space){\psPrintValue{\nx\space
\ny\space mul}}
	}
}
\end{psgraph}
\end{document}

but I would like to control everything with postscript variables, for
instance as follows (which does not work):

\documentclass{article}
\usepackage{multido}
\usepackage[x11names]{xcolor}
\usepackage{pst-tools}
\usepackage{pstricks-add}


\begin{document}
\pstVerb{/nxmax 5 def /nymax 4 def}
\psset{linecolor=red}
\begin{psgraph}[arrows=->](0,0)(!nxmax nymax){5cm}{5cm}
\multido{\ny=1+1}{!nymax}{
	\multido{\nx=1+1}{!nxmax}{
		\uput{0pt}[90]{0}(!\nx\space \ny\space){\psPrintValue{\nx\space
\ny\space mul}}
	}
}
\end{psgraph}
\end{document}

How can I make it work?
