[pstricks] Node Coordinates

[Douglas Reid]

Thanks, Herbert - that works well!

I need to use the distance between the nodes to define other things within LaTeX.

Can this command be simply modified to get the result back from the PostScript calculation into LaTeX?
i.e, to get the distance into a LaTeX length variable.

%Usage: \setDistance{length}{NodeA}{NodeB}

\def\setDistance ...
...

\newlength{\distanceAB}
\pnode(0,0){A}
\pnode(3,4){B}
\setDistance{\distanceAB}{A}{B}
