I guess I wasn't too clear. Microchip uses the standard shift-and-XOR algorithms to produce their pseudo-random sequences. By the way, I assume from that "they (you)" bit that you may be under the impresion that I work for Microchip. While my company does a fair amount of work for them, I am not an employee. The PROMATE software was written by Jim Pepping (and, perhaps, others) at Microchip; as far as I know, no outside talent was utilized. -Andy Andrew Warren - fastfwd@ix.netcom.com Fast Forward Engineering, Vista, California http://www.geopages.com/SiliconValley/2499
