Did not know that. And it works, PASS. Thanks so much! Then the question is, I'd like to do some more validation on Attrib via the semantic action, but I don't know what it is. It seems like it should be a std::string, but I don't think it is, or is it a vector? >> Dne st 3. 1. 2018 4:15 uživatel Michael Powell <[email protected]> >> napsal: >>> >>> At this point I'm just scratching my head.
