This will allow me to experiment with DFA lexing which results in a sometimes dramatic improvement in parsing time for some worst-case COBOL source programs (parse times 50% of NFA times). In typical cases the improvement is less significant (parse times 70 to 90% of NFA times). The DFA lexing time is usually about 30-50% of the NFA lexing time.
