I am offering a course with the title "Program Dynamics" at the International Institute of Information Technology, Hyderabad, India, for the second time around. The course is based on the book IMCS with some additional topics. On occasion, it becomes necessary to present details to students that are omitted in the book. Again, on occasion, I think that perhaps a more elementary way of presenting a topic than in the book is possible. All such additional material, if it finds its way to being written up neatly, appears below.
