Hello


Given a free-context grammar, I'm trying to write a recursive descent
parser for this grammar, with a minimum of function:


That is, the only things I want to do, for the beginning, is only:
incrementing the actual index in the tested string, and testing
whether string[index]==x, where x is a token; maybe saving and
restoring the index too..


The dragon book is a bit quick on this subject, and i've found nothing
that explain this algorithm well on the net


Thanks for any advice!
