Thankyou - a definitive answer. I will print it out and frame it :) This suggest that Conrad's analysis is not quite right then, since even if I'm overflowing the 32-bit integer, there's still enough variation in what remains to give a valid and usable seed: 2011-05-27 14:25:14.689 Squaresgame[83159:a0f] seed: 276132753 2011-05-27 14:25:14.691 Squaresgame[83159:a0f] random: 1826068185 2011-05-27 14:49:36.081 Squaresgame[83217:a0f] seed: 290746671 2011-05-27 14:49:36.083 Squaresgame[83217:a0f] random: 162579918 --GRaham _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
