Assuming 16 bit numbers on the Z-80 the maximum integer is 2^16-1 = 65,535. Assuming 32 bit numbers on the M68000 the maximum integer is 2^32 - 1 = 4,294,967,295. So, assuming nothing funny was going on, the TRS-80 II was only doing the loop 65,535 times and the Apple Lisa did do the loop 10,000,000 times. BTW it took exactly 16 seconds on a unloaded DEC-20 written in Pascal (unoptimized). Jeff -------
