Interestingly, I didn't have this file, and when I searched the download source it wasn't there either! Funny. I got a copy of bison.simple from an MIT server and put it in the bison.exe directory, but that didn't solve the problem. It also didn't have any "output_parser_name" variables. > Re-installing bison may solve the problem. Unfortunately, no. I'll keep looking. jz
