"MathPad" and "Science.Wri" are copyrighted. Each one can be registered
separately for $10.00, or you can register both for $18.00. "D" is also mine
but I'm releasing it into the public domain. It can't be registered, but as
the closing screen indicates I would welcome a 2 or 3 dollar contribution for
"D". "Science.Wri" is for Microsoft Windows 3.1, the built-in 'Write' module.
If you can't get to a computer with Windows before 30 days, for heaven's sake
hold on to the file till you can read it. It's a book describing stars,
computers, science, and my own upbeat view on the relationship between science
and Christianity.
