This is the first program I wrote to be released as shareware. It is a DOS program written and released in 1989. It may or may not work on your modern PC, so try it first. On mine it only works in full screen DOS mode. I don't really expect to receive any more shareware payments from this program, but I put it on this site for posterity's sake. Of course, if you like it you may still pay or make a donation.
