I've been thinking about making one for a while, and I have a good menu routine now (best I could do.. I'm not so good with strings..)
For the menu I have it set up like this:
Every 20 letters (I keep changing the amount.. probably will stay with 20) the program makes it into a new string (each one is Str2) and displays it on the next line on the graph screen. (I am using the graph.. it has more room for text.)
There's probably a better way to do it then that, but it's the easist way, I find. But, for memory it probably adds just a little because for each different option it is 20 letters.
Then, to select the definition or equation, you press the number that is to the left of it.
I have it like:
1. Something Angle Related
2. Something Else
If it is an equation it opens in the main calculator part; if it is a definition it opens in the graph screen to have more room to type (and maybe put an example.)
To change the chapter or section you press the arrow keys (up and down for chapter; left and right for section.)
I mainly think the menu could be optimized but other then that.. I think it's pretty good. :D
