   \subsection{Mathematica}
   
   We provide an OpenXM client {\tt math2ox} written as an external module
   for Mathematica.  Our client communicates to Mathematica by MathLink and
   to an OpenXM server by OpenXM protocols.
   By using the module {\tt math2ox},
   we can call OpenXM servers from Mathematica;
   here is an example of a computation of the de Rham cohomology groups
   of ${\bf C}^2 \setminus V(x^3-y^2)$.
   {\footnotesize
   \begin{verbatim}
   In[1]:= Install["math2ox"]
   In[2]:= OxStart["../lib/sm1/bin/ox_sm1_forAsir"]
   In[3]:= OxExecute[" [(x^3-y^2) (x,y)] deRham "]
   In[4]:= OxPopString[]
   Out[4]=  [ 1 , 1 , 0 ]
   \end{verbatim}
   }
   
   \subsubsection{Functions}
   
   The {\tt math2ox} has the following functions
   which respectively correspond those in Risa/Asir.
   \begin{quote}
   {\tt OxStart[s\_String]} \\
   {\tt OxStartInsecure[s\_String]} \\
   {\tt OxExecuteString[s\_String]}  \\
   {\tt OxParse[s\_String]} \\
   {\tt OxGet[]} \\
   {\tt OxPopCMO[]} \\
   {\tt OxPopString[]} \\
   {\tt OxClose[]} \\
   {\tt OxReset[]}
   \end{quote}
   For example, the {\tt OxPopCMO[]} function above requests a server to
   send data on the stack to the stream, then it receives the data from the
   stream.
   
   By using the {\tt OxParse[]} function, we can send suitable OX messages,
   written by the OX expression, to a server.  OX expressions are
   Lisp-like expressions for OX messages and are defined
   in~\cite{noro-takayama}.
   The {\tt OxGet[]} receives an OX data message
   and returns its translation to an local object.
