  Enter a process you wish to compute. The generic form is
P1[,P2]-> P3,P4 ... [N*x]. Here P# is a particle name, N is the
number of inclusive particles. The particle names may be chosen
from the table in the upper part of the screen. N may be chosen
among 1,2,3. The total number of particles cannot exceed 6.

 Examples:  
     A,A->W+,W-  
     e1,E1->H,2*x 
     A,e1->e1,1*x

If the name of an incoming particle is absent from the table, the
user is prompted to describe this particle as a composite one.
