  The Table {\it Parameters} consists of three fields:

\begin{enumerate}
\item {\it Name} for an identifier of the parameter. It may
contain up to 6 characters. The first character
must be a letter, others may be either letters or
digits; 
  
  \CompHEP~ identifiers are sensitive to the case of characters. Also names
of different identifiers must be different after rewriting them
in the low case. For example, if the identifier "Me" is
used in the table for the electron mass, then
the forms "ME", "mE","me" are forbidden as for new 
definitions as for identification of the electron mass.

  There are some reserved names which cannot be used
here:
\begin{itemize}
\item {\tt i}    is reserved for imaginary unity;
\item {\tt Sqrt2} is reserved for $\sqrt{2}$;
\item {\tt p1,p2,p3,\ldots} are reserved for particle momenta;
\item {\tt m1,\ldots,M1,\ldots} are reserved for Lorentz indices of 
                particles;
\item {\bf G5} is used for the $\gamma^5$ Dirac matrix;
\end{itemize}
    
\item {\it Value}   for a numerical value of  parameter in some power of 
{\it GeV} units;

\item {\it Comment} for brief description of a parameter.
\end{enumerate}
