The user can extend Survo by new operations. There are three main
alternatives:

1. The new operation is programmed in C. Information can be found in
   the report  S.Mustonen: Programming SURVO 84 in C .
   Information about programming SURVO MM program modules
   can be obtained from S.Mustonen on request.

2. The new function is constructed as a sucro by using existing
   operations as building blocks.

3. Matrix chains

  S = Sucros 
  M = Matrix chains (MATRUN)
