But the grammar must still be a bit complex as sometimes the LHS of the = is an expression, as well as the RHS. But I guess context makes it all work. Still I've always thought the grammars for modern BASIC with all its baggage must make for a complex grammar. -- https://mail.python.org/mailman/listinfo/python-list
