I *think* I understand Marshall here. When you are saying "assignment", you mean assignment to values of attributes within tuples of the cell. When Marshall is saying "assignment", he seems to mean assigning a completely new *table* value to a relation; i.e., wiping out the entire contents of the relation and replacing it with a whole new set of tuples. Your assignment is indeed less powerful than DML, whereas Marshall's assignment is more powerful than DML. -- Chris Smith - Lead Software Developer / Technical Trainer MindIQ Corporation -- http://mail.python.org/mailman/listinfo/python-list
