    Stefan.Keul> My question is now:

    Stefan.Keul> existing?

  I can only answer for Unix systems, which are the only ones I can access.
For them, there is no problem to describe the complete pathname of the files
using TeX macros (there are nevertheless some restrictions: as it is easy to
verify, the "~" convention doesn't work).

  But I can't say anything for PC/Mac systems. 

\documentclass{article}

\usepackage{pst-plot}

\pagestyle{empty}

\begin{document}

\newcommand{\HomeDir}{/u/alg/girou}
\newcommand{\DataDir}{tex/PST/Plots}
\newcommand{\File}{test}

\begin{pspicture}(-2,-2)(2,2)
  \readdata{\test}{\HomeDir/\DataDir/\File.data}
  \dataplot[plotstyle=line]{\test}
  \psaxes{<->}(0,0)(-2,-2)(2,2)
\end{pspicture}

\newcommand{\HomeDirB}{/u/alg/girou/}
\newcommand{\DataDirB}{tex/PST/Plots/}

\begin{pspicture}(-2,-2)(2,2)
  \readdata{\test}{\HomeDirB\DataDirB\File.data}
  \dataplot[plotstyle=line]{\test}
  \psaxes{<->}(0,0)(-2,-2)(2,2)
\end{pspicture}

\end{document}
