I'm not sure I understand your question: do you have existing tables that you'd like to plug in to a parser tool, or are you looking for the (E)BNF source needed to generate tables? There are some parser tools, e.g., Gold (http://goldparser.org), that separate the tables and actions from the "engine" that executes them, and that can demand load new table/action sets. However, I'm not aware of any tool that can directly use pre-existing "foreign" tables ... every tool I know of has to have generated the tables itself. George
