I very hope on this btw, because ANTLR 2.7 parser, which we have used in
Valentina was, for example, slower about x4 times of Lemon parser used in
the SqlLite. So our SQL commands e.g. have work slower of SqlLite, while
Valentina engine itself (if not use SQL) do inserts x20 times faster ...

Jim, I hope you have see that I have TWO days jump over all pages ...
And of course I have read all this already.

Yes, I already have copy it and replace to sprintf()  into char buffer.

I did search and google, and StackOverflow, and Antlr list...
I have read EACH letter about "exception" for last 5 years on list.
