I never looked at the lexer internals so I can't debug it. (Note BTW that Nora's program is highly sensitive to any little grammar changes, and Nora's program needs the output that the official parser puts out with -t in order to work; I don't know if you are planning a similar output format, but I hereby request it). lojbab -- lojbab lojbab@lojban.org Bob LeChevalier, Founder, The Logical Language Group (Opinions are my own; I do not speak for the organization.)
