Dear Peter, I read your project and liked it very much. A couple of things: you have FIXMEs in some places ... did you? Did you implement p2k procedures? It would be helpful for me to see the problem statement as well as the p2k bnf or language definition. Would you post that information? Sincerely, Douglas M.
