[antlr-interest] Re: Antlr noobie, nondeterminism abounds

Loring, Bryan, & Mark:

Thanks for all your help!  Your explanations and suggestions have been
spot on!  It sounds like I picked quite the project to cut my teeth on
lexer/parser fundamentals.  I may be in a little over my head for
right now. :)

Mark, I couldn't quite tell from your reply if you thought that maybe
a lexer/parser is the wrong tool for the job in this case:

Is this using a hammer when a screwdriver is what's needed?  My
project is to parse IMAP server replies (formatting the requests isn't
too difficult), so it's not a necessity that it be done in a
parser-generator if that's not the right avenue to take.

Cheers,
