Hi, Bison doesn't like the grammar at all: "said.y contains 10 shift/reduce conflicts and 1 reduce/reduce conflict." (yacc reports the same). By setting the operator precedence of '<' to 'left', I reduced it to 9 s/r conflicts, but that's all. I think that the results are now correct if only one word group is being used; in all other cases, results are broken. I'll check in the results anyway. I think I'll be able to get rid of the r/r conflict, but I'm not sure if I understand the grammar well enough to take care of all s/rs. llap, Christoph
