The first thing that hit me when I read the post about the C benchmark running in 4 seconds on a Z80 was the fact that it would have to be doing about 2.5 million 32-bit decrements and conditional branches per second (!) - I'd love to have such a machine!! Z80's don't have a 32-bit DJNZ instruction! I guess BDS C doesn't believe in compile-time range-checking of constants: the program must be counting 10M modulo 64k, or some such. But, then, 16-bit ints would make a lot of sense on a z80. Mark Dzmura -------
