Y.TXT (c)1991 by Dave Byter, proliferate freely. Why am I giving away this valuable information? Several reasons, including the philosophical belief that information is free. The one that is important to you is that this is advertising for the surveying instruments. I'm content to take my profit on the compass and tape. If, in addition, every reader would send me a buck and pass copies on to two of his/her/its/their friends who would do the same within one week I'd be delighted. After a year, I would not be delighted. I'd have every poor relative, investment advisor, and tax collector beating a path to my door. $2^52 is a LOT of dollars, even by Department of Defense standards! I promise that I will pay off the National Debt, and then buy Kentucky and give it back to the Indians if you good people out there will just send me $2^52. That's even enuf that I could retire with the change left over after my philanthopy. I might even buy the New World and give it back to the cave bears.
