[antlr-interest] using the generatred parser and lexer classes

[Ketan Maheshwari]

Hello Jose

Thanks for your reply.

Yes, after putting the option output=AST, i got the result as you
mentioned.

But now i have another issue. The program never returns from the line where
we create an instance of the parser :

gscriptParser g = new gscriptParser(tokens,49100,null);


Thanks for any inputs
Ketan
