Hi Jim,
I tried this, and it works fine. I tchanged it to be just LA(1)
instead of input.LA(1) to have it work in C.
I also tried the solution from John,
fragment PART : '"' (options{ greedy=false; }: .)* '"' ;
STRING : PART+ ;
which worked fine too, and which I found easier to understand.
Are there any advantages or disadvantages to these two solutions?
Thanks
Anders
