It should say: |However, off the top of my head, I don't understand why you can't parse |an Ada expression using recursive descent, especially since you have |access to the symbol table (if you need it to solve the specific problem |you are thinking of). IOW, I _think_ all ambiguity should be resolvable with a suitably rich symbol table. Clearly that's not the case - and there's probably some really obvious case I am missing. :-) Simon. -- Simon Clubley, clubley@remove_me.eisner.decus.org-Earth.UFP Microsoft: Bringing you 1980s technology to a 21st century world
