  Ivan Maio <maio at polito.it> report today the following problem: the
(coor1|coor2) special coordinates (see documentation page 72) produce an error
at compile time.

  Reason is that it was a bug in PSTricks 0.93a, corrected with entry 20
in 1994 pstricks.bug. But this correction was missing in PSTricks 97
distribution.

  Correction is:

\documentclass{article}

\usepackage{pst-node}

\makeatletter
\def\mixed at coor#1#2{%
\begingroup
\special@@coor#1;;\@nil
\let\pst at tempa\pst at coor
\special@@coor#2;;\@nil
\xdef\pst at tempg{\pst at tempa pop \pst at coor exch pop }%
\endgroup
\let\pst at coor\pst at tempg}
\makeatother

\pagestyle{empty}

\begin{document}

\SpecialCoor
\pnode(1,1){A}
\pnode(4,4){B}

\psdots(A)(B)

\psdots[linecolor=red](A|B)

\end{document}

  This is patch 6 for pstricks.tex 93a/b-97:

  * 97/10/27 pstricks.tex (93a/b-97 patch 6): the (coor1|coor2) special
coordinates produce an error, due to a bug in 0.93a version, which correction
in pstricks.bug was not reported in PST 97.
