\Lcs{cnode}, in contrast to \Lcs{pnode}, creates a circular node with defined
radius. Again you can put the node anywhere within text
\makebox[2ex]{\cnode{1ex}{A}} (\verb+\cnode{2ex}{A}+). The centre of the node is
on the base line. Note that \Lcs{cnode} doesn't reserve any space, so it's a good idea
to put it inside a \Lcs{makebox} when using it in text.
\begin{center}
\begin{pspicture}[showgrid](2,2)
\cnode[linecolor=red](1,1){3pt}{B}
\nccurve[arrows=->,linestyle=dashed,angleA=-90,angleB=200]{A}{B}
\end{pspicture}
\end{center}
\end{document}
