Greetings:

If we are indeed going to produce a programmable calculator utility
that will run on the PC, it is important, I feel, that we treat it
as a fully functional computer utility and build in all of the
functionality that computer users have come to take for granted in
PC-based utilities. Such functions might include:

1. The ability to backspace when one has made a mistake entering
     information;

2. Context sensitive help;

3. The ability to jump out of the current function back to a
     higher level using the Escape key;

4. Ensuring that all calculations are performed with accuracy and
     correct precision;

5. The ability to have all calculations displayed on the screen
     for later review;

6. Online documentation--in addition to braille documentation.

That's all of the functionality I can think of for now. I look
forward to whatever emerges from Dr. Nemeth's capable work.

Cordially,

Curtis Chong
