[pstricks] Reading data with raw postscript

[Poul Riis]

How can I read data from a file with raw postscript commands (see
not-working-example below)?
I guess it has something to do with \ but I also tried to replace it with
/.

Yours,
Poul Riis



\documentclass{article}
\usepackage[svgnames,x11names]{xcolor}
\usepackage{pstricks-add}
\usepackage{geometry}
\makeatletter
\def\psReadfile{\pst at object{psReadfile}}
\def\psReadfile at i#1#2{%File name, number of columbs
   \begin at SpecialObj
   \addto at pscode{
/inputdatafile (#1) (r) file def
%%%%%%%%%%%%%%%%%  read data commands, for instance from
http://www.fho-emden.de/~hoffmann/pstutor22112002.pdf
inputdatafile closefile
   }%
   \end at SpecialObj}
\makeatother


\begin{document}
\psset{unit=1cm}
\begin{pspicture}(-2,-2)(10,10)
\psaxes[ticksize=-3pt 0]{->}(0,0)(-2,-2)(10,10)
   \psReadfile{D:\miktex\filereadertest.dat}{2}%File name, number of
columbs
\end{pspicture}\\[1cm]
\end{document}
