ok thanks. I have tried to find a solution to my problem without 
success. I feel like just
a little thing is missing, like a \endcsname:

\begin{figure}[h]
\newarray{\Months}
\readarray{Months}{1&2&3&4&5&6&7&8&9&10&11&12}
\begin{pspicture}(-2.4,-3)(8.5,3)
\multido{\i=1+1}{12}{\psline[linewidth=1pt]{->}(\value{\Months(\i)},0)(\value{\Months(\i)},1)}
\end{pspicture}
\end{figure}

Thank you

M.
