An unexpected benefit of cleaning out our basement and putting our belongings in storage has been finding a trove of work I thought had been lost, in a stash of 3½ floppies, no less. I uploaded a sample to a couple of folders on Google Drive.
The first contains a minimal set of files for running the program.
The second contains the example files mentioned in the User Guide.
Apologies in advance for Theme One being a bare prototype, a “text of concept” sort of program. The user interface is pre-mouse and very finicky but I, its mother, was able to nurse it along far enough to learn a lot from it, and many are lessons of still timely pertinence to our perennial issues.
