The design of a given grammar and the corresponding set FIRSTVT and LASTVT can based on the basis of grammar and LASTVT generated FIRSTVT and analysis of operator priority table. Dynamic simulation algorithm is the basic functions: 1. The importation of a given grammar, and FIRSTVT and LASTVT set 2. Analysis of the output operator priority table generation algorithm 3. Analysis algorithm output priority of the process of tectonic processes
