Consider the following code.
\documentclass[pstricks,border=12pt]{standalone}
\SpecialCoor
\begin{document}
\begin{pspicture}[showgrid](-5,-5)(5,5)
\pscustom
{
\psline(1,0)
\rlineto(0,1)
%\translate(!!CP.x 0) % does not work!
}
\end{pspicture}
\end{document}
I want to separately access the abscissa and ordinate of the current point, how to do so?
