I am currently teaching myself lex and yacc by reading the lex & yacc
book from O'Reilly & Associates. The 2nd edition is a great
improvement over the 1st which I had tried several years ago. The
O'Reilly web site says that John Levine manages this newsgroup so I was
especially hopefull that I could have some additional information.

I am finished with chapter 3 and doing the exercises at the end they are
getting a bit difficult and open ended. Problem number 7 is very
interesting to me, because my basic intention is to create a domain
specific language that the calculator example seems to be moving me
towards. (Problem 7 gives some pointers on how to extend the calculator
to have user defined functions.)

Question 8 asks a question that I think I prefer the book to have
answered. My sense is NO, but I don't have anything to back it up

Thus I have the following question:

Where can I find the answers to the exercises? Is there a source?

Any help would be most appreciated.

[Hey, I just wrote the questions. You get to write the answers. But
the answer to question 8, would it be a good idea to expand the desk
calculator example into a full-fledged programming language, is no,
because the world doesn't need yet another language that's sort of
like Fortran but not very. -John]
