Computer programs written by Roger Bakeman, GSU

I wrote these computer progam in Borland's Delphi (various versions). They run in a Windows environment (95, 98, ME, XP, Vista, Windows7). I provide them free of charge but for non-commercial purposes only. I hope you will find them useful. To the best of my knowledge they work as described, but of course I make no guarantees. Still, if you think something does not work right, email me and let me know. In the spirit of shareware, if you find these programs useful, I would be delighted if you would contriubte $25 in my name to the Georgia State University Foundation (Georgia State University, Atlanta, GA 30303), indicating it as a contribution to the Psychology Department Enhancement Fund.
