So if endianness generally describes the byte order, not the bit order, then either each value (two, four or eight bytes) is reversed or the entire string is reversed. Hopefully it's the former rather than the latter, as that would be easier to compensate for. While it would be slow, I could just write functions for flipping the byte order of characters in a string. That would work fine for the client but may impact performance server side. I'll do some experimenting tomorrow to see what I can come up with. -- Kevin Fishburne Eight Virtues www: http://sales.eightvirtues.com e-mail: sa...@eightvirtues.com phone: (770) 853-6271 ------------------------------------------------------------------------------ Xperia(TM) PLAY It's a major breakthrough.
