This is the PSTricks mailing list, devoted to discussions about computational
graphics in (La)TeX using the PSTricks package from Timothy van Zandt.

  Pierre Basso <Pierre.Basso at lim.univ-mrs.fr> recently report that changing
the refpoint parameter of the \rnode macro has no effect.

  It was working both in 0.93 version and with pst-beta, but the problem was
introduced in the pre-0.94 version we used to build PSTricks 97.

  In fact correction is easy, as only one obvious line was missing.

  In CHANGES file:
............................................................................
  * 98/04/28 pst-node.tex (97 patch 6): The refpoint parameter of the \rnode
macro is not used if it is specified.
(reported by Pierre Basso <Pierre.Basso at lim.univ-mrs.fr>)


  Thanks for the report, Pierre!

  My test case is:

\documentclass{article}

\usepackage{pst-node}

\pagestyle{empty}

\begin{document}

\LARGE
\psset{subgriddiv=0,linecolor=red,linewidth=1mm}

\begin{pspicture}(5,4)\psgrid
  \rput(1,1){\rnode{A}{AAAAA}}
  \rput(1,3){\rnode[l]{B}{BBBBB}}
  \rput(4,3){\rnode[r]{C}{CCCCC}}
  \ncline{A}{B}
  \ncline{A}{C}
\end{pspicture}
