如何使用 PSTricks 压缩 \ncline 命令

这个问题在 LaTeX 中绘制图表。

\documentclass[12pt,border=5pt]{standalone}
\usepackage{newcent,pstricks,amsmath,amssymb,pst-arrow} 
\usepackage{auto-pst-pdf}

\makeatletter
\newcommand\NCline[2]{\ncline{#1}{#2}\@ifnextchar\bgroup\NCline{}} %% :-))))
\makeatother
\begin{document}
\begin{pspicture}
\begin{psmatrix}[colsep=12mm,rowsep=10mm]
           & [name=A1] $000$ &     &  [name=A2] $111$  &      &   \\
        &     &  [name=A3] $111$ &     &    [name=A4] $110$  &   \\
     & [name=A5] $011$ &   &  [name=A6] $110$  &   & [name=A7] $100$ \\
[name=A8] $001$  &  &  [name=A9] $101$ &  &  [name=A10] $110$    &
\end{psmatrix}
\psset{nodesep=5pt , arrows=->, arrowsize=5pt, arrowlength=1}
\ncline{A1}{A3}{A3}{A2}{A2}{A4}     
\ncline{A5}{A3}{A3}{A6}{A6}{A4}{A4}{A7}     
\ncline{A8}{A5}{A5}{A9}{A9}{A6}{A6}{A10}{A10}{A7}
\end{pspicture}
\end{document}

我遇到了错误。如何解决？如果你有更短的方法，你可以改进它。

\foreach \i/\j in {1/3,3/2,2/4,5/3,3/6,6/4,4/7,8/5,5/9,9/6,6/10,10/7}{\ncline{A\i}{A\j}}更优雅，不是吗？

\documentclass[preview,12pt,border=5pt]{standalone}
\usepackage{pst-node}
\begin{document}
\begin{psmatrix}[colsep=12mm,rowsep=10mm]
    & [name=A1] $000$ &                             & [name=A2] $111$       &                               &   \\
  &                             & [name=A3] $111$ &                                     & [name=A4] $110$   &   \\
  & [name=A5] $011$ &                               & [name=A6] $110$       &                                   & [name=A7] $100$ \\
[name=A8] $001$         &                               & [name=A9] $101$       &                                   & [name=A10] $110$   
\end{psmatrix}
\psset{nodesep=5pt,arrows=->,arrowsize=5pt,arrowlength=1}
\foreach \i/\j  in {1/3,3/2,2/4,5/3,3/6,6/4,4/7,8/5,5/9,9/6,6/10,10/7}{\ncline{A\i}{A\j}}
