You underdefine the problem. What happens in the case of: BRM_1 ... BRM_1 ... BRM_2 ... BRM_1 ... <-- duplicates a (not-immediately) previous line BRM_3 ... Also, do the values that follow have any significance for this, or are they just noise to be ignored? -tkc -- http://mail.python.org/mailman/listinfo/python-list
