Post #347,574 by SpiceWare 9/9/11 11:19:45 PM Reply	thanks looks like I'm doing a variation of the "obvious way", though mine is interleaving the value with itself. table lookup would probably be best - think I'll do it with a 16 byte table and double up each nybble as a 512 byte table would take up too much room.
