Yes I have. I was hoping for a different perspective because what I'm trying to
do is middle out parsing. Top-down when the scanner focus moves from left to
right and bottom up when the scanner focus moves from right to left.
sounds kind of odd when I describe it that way but both the cursor is on the
middle of a name string and I need to look to either end of that name string
before can do a conversion to a symbol string, I have to look at both ends in
different ways. If you've read the documentation I've provided, would it be a
better example to use for describing some of the issues. Here's a very rough
draft of a storyboard
https://docs.google.com/presentation/d/1fuKyo9AE6i9ZdX2lucwK0v_W5Kx9M3Mezavm40wzCo8/edit
the first 13-14 slides are the working content for the storyboard. the rest is
mostly "memory" of things I was thinking about so if it doesn't make sense or
seems wrong, don't give me grief. :-)
Here's a Python parser using the pyparsing library. It's a bit old
(written for Python 2.4) but it shouldn't be hard to update it to new
syntax:

thanks for the reference. I'll take a look at it as well.
