I was interested in seeing what could be done with the graph screen, and I started to learn some of the commands. I started out with learning how to graph a basic cursor:

Code:
``` Pxl-Change(B,A Pxl-Change(B+1,A Pxl-Change(B+2,A Pxl-Change(B+3,A Pxl-Change(B+4,A Pxl-Change(B+5,A Pxl-Change(B+6,A Pxl-Change(B+7,A Pxl-Change(B+8,A Pxl-Change(B+9,A Pxl-Change(B+10,A Pxl-Change(B+11,A Pxl-Change(B+11,A+1 Pxl-Change(B,A+1 Pxl-Change(B+2,A+3 Pxl-Change(B+4,A+5 Pxl-Change(B+6,A+7 Pxl-Change(B+7,A+6 Pxl-Change(B+7,A+7 Pxl-Change(B+8,A+5 Pxl-Change(B+9,A+5 Pxl-Change(B+10,A+6 Pxl-Change(B+10,A+7 Pxl-Change(B+11,A+7 Pxl-Change(B+12,A+7 Pxl-Change(B+13,A+7 Pxl-Change(B+13,A+6 Pxl-Change(B+13,A+5 Pxl-Change(B+13,A+4 Pxl-Change(B+12,A+4 Pxl-Change(B+11,A+4 Pxl-Change(B+10,A+4 Pxl-Change(B+9,A+3 Pxl-Change(B+1,A+2 Pxl-Change(B+3,A+4 Pxl-Change(B+5,A+6 Pxl-Change(B+10,A+2 ```

Then, using Kerm's book on coding, I made a program that allows the user to move the cursor around the graph screen. (I still need to finish optomizing it for ti 84 plus CE)

Code:
``` 120->A:80->B AxesOff:ClrDraw Repeat K=45    prgmCURSOR1    Repeat K       getKey->K    End    prgmCURSOR1    If K=24 and A>5    A-4->A    If K=26 and A<250    A+4->A    If K=25 and B>4    B-4->B    If K=35 and B<200    B+4->B End AxesOn ```

What I want to do now, is have different icons that represent different programs I have made. Then you could move the cursor over, hit enter, and then it would run the program. I think I will just make more subprograms that draw each one of the icons for my programs, but I don't know how to have it check to see if the cursor is over one of the program icons.
Very nice! Btw, you can significantly optimize your CURSOR1 program, if you just use some For( loops:

Code:
``` For(I,0,11 Pxl-Change(B+I,A End Pxl-Change(B+11,A+1 For(I,0,6,2 Pxl-Change(B+I,A+I+1 End //I cant really find a pattern with the rest of it Pxl-Change(B+7,A+6 Pxl-Change(B+7,A+7 Pxl-Change(B+8,A+5 Pxl-Change(B+9,A+5 Pxl-Change(B+10,A+6 Pxl-Change(B+10,A+7 Pxl-Change(B+11,A+7 Pxl-Change(B+12,A+7 Pxl-Change(B+13,A+7 Pxl-Change(B+13,A+6 Pxl-Change(B+13,A+5 Pxl-Change(B+13,A+4 Pxl-Change(B+12,A+4 Pxl-Change(B+11,A+4 Pxl-Change(B+10,A+4 Pxl-Change(B+9,A+3 Pxl-Change(B+1,A+2 Pxl-Change(B+3,A+4 Pxl-Change(B+5,A+6 Pxl-Change(B+10,A+2 ```

And also:

Code:
``` A+4((K=26)(A<250)-(K=24)(A>5))->A B+4((K=35)(B<200)-(K=25)(B>4))->B ```
Yah, I realized the power of loops when making my factorial icon

Code:
``` ClrDraw 50->C 50->D While C<79    Pxl-On(C,D,Black    C+1->C End While D<79    Pxl-On(C,D,Black    D+1->D End While C>50    Pxl-On(C,D,Black    C-1->C End While D>50    Pxl-On(C,D,Black    D-1->D End Pxl-On(C+21,D+13,Red Pxl-On(C+22,D+13,Red Pxl-On(C+21,D+14,Red Pxl-On(C+22,D+14,Red Pxl-On(C+21,D+13,Red 69->C 63->D While C>57    Pxl-On(C,D,Red    C-1->C End 64->D While C<69    Pxl-On(C,D,Red    C+1->C End 54->D 54->C While C<75    Pxl-On(C,D,Black    C+1->C End While D<75    Pxl-On(C,D,Black    D+1->D End While C>54    Pxl-On(C,D,Black    C-1->C End While D>54    Pxl-On(C,D,Black    D-1->D End Pause ```

I know that there is still more that I need to do to optimize this. I think what I am going to do is when Enter is pressed, check to see if B and A are inside of the range of the factorial icon. It still needs a lot of work, but I have made a lot of progress. Thanks for the help.

EDIT: Here is how it looks now.

So let me know if I understand. You're trying to make a basic GUI in TI-Basic for launching some of your own programs?

Just a couple things I forsee...
First of all, if someone deletes the program you're planning to launch... Perhaps use an ICE program to extract program names and store it in a string, then check that? IDK I'm just naming some thoughts.

Anyway looks really cool so-far. You could try (just as an exercise, I have no idea how hard this would be) building some other interactive GUI elements we know and love (i.e. 'windows', or just boxes you can move, check boxes, scrollbars, etc.).
