Sorry, that's wrong. It won't make any difference to the padding, since arrays don't have padding in C: sizeof(char[3]) is 3, and sizeof(char[3][84]) is 3*84=252. So your problem is likely just the difference between sizeof(long) from one platform to another. Mark -- http://mail.python.org/mailman/listinfo/python-list
