That's a fun (and useful) thing on the Prime. Noted, I still haven't touched the subject. Right now I started on the Forms and UI but then it occurred to me that I needed a few things first: * Variable properties: A variable can have properties now. I have a couple in mind that will be used by the Forms framework, for example a preferred unit for display. * An event framework to trigger something when a variable changes, which will help build applications more easily. The idea is that you create a variables, 'A', 'B', for example, and define a program that does for example C=A+B, triggered every time A or B change. Then that idea mutated into automatic evaluation of a tree of those triggers. Now you define 'A' with a value, 'B' with a value, and 'C' with the formula 'A+B', and the system will automatically recalculate C every time A or B change. Then if you define 'D' = 'C^2', changing A will recalculate C that will trigger a recalculation of D. This way you can work through problems and when you finish, changing the input data gives you a new solution automatically. The Forms would become more of a text template to display these variables, their formulas and the values intermixed with explanations, text and possibly graphics. It leans more towards MathCAD (or SMath studio, same thing) rather than the traditional INFORM. |
