I understood the logical distinction, I guess I should have said "most of the benefits of a pointer without many of the potential headaches". Pointers in C are REAL memory addresses, HOWEVER, in many (if not most) situations they are used as symbol table aliases. It's when they AREN'T carefully used this way that memory overwrites happen. As I said, most of the good without most of the bad. :) -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
