Hi, Jim,
Thanks very much for your help
I tried to turn backtrack off before, but failed to build the grammar with a
lot of errors, so I have to turn it on

Thanks
grammar Sybase;

backtrack = true;
Hmmm - backtrack = true isn't a good idea for something like SQL (or almost
any production parser really) - this may be masking your issue, but I will look
at this for you this weekend - apologies that I am too busy to look a this
before then.
Also, my own parser matches the comments in the lexer and places them on
their own channel. You can then look for them in the tree walker if you need
them.
