I've used this technique before. It is very useful where (as in the original re example) recursion might cause a large traceback, and the error is probably caused by the caller's code. Using this technique can keep the visible portion of the traceback relevant to the problem at hand. Regards, Pat -- http://mail.python.org/mailman/listinfo/python-list
