The problem is that our scanner is rather complicated (lexical analysis for PHP is not easy), and I'd rather not have the logic of the "bean counting" as you refer to it mixed throughout with the logic of the token generation. I've considered modifying YY_INPUT to keep count automatically, but then you have to worry about the scanner looking ahead and then backtracking, calls to yyunput, etc. Edsko _______________________________________________ [email protected] http://lists.gnu.org/mailman/listinfo/help-bison
