2 9 76   Parameters
             This table consists of three fields:
1. "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. But any two
identifiers must be different after rewriting them in low case.
   There are reserved names, which cannot be used here: 
  "i" is used for imaginary unit;
  "Sqrt2" is used for sqrt(2)
  "p1","p2","p3",.. are used for particle momenta. 
  "m1","m2","m3",.. are reserved for Lorentz indexes of particles.
   G5 is used for the gamma-five Dirac matrix;
2. "Value" for numerical value of the parameter in  GeV units;
3. "Comment" for brief description of a parameter.
