[antlr-interest] how can i get a return string from the parser

[Su Zhang]

Hi Gavin

but the class cannot be applied by the outside source, right? then how can
get the value out of the program? i mean i want to call the function in the
main function, yet it is generated in the internal class of the parser
class, right? then how can i get this value in the main fuction?

thank you
