In the previous replies I saw a lot of information about parsing, how
the parser performs recognition of the input (bottom up and top down),
but nothing about AST generation. It seems the original poster meant
to say parse tree instead of AST tree. Let's try to use the correct
terms for these things so there is hope for those who are trying to
learn from this discussion group.


AST generation is easily done with the LRgen product at
