HOW TO USE THE DRAWING COMMANDS ON THE TI83 (+) ?
On the TI83 (+) there are drawing commands :
1) to trace a line
:Line(X,Y,X',Y')...............Trace a line from A to B. (X,Y) are the X ans Yvalues of A and (X',Y') are the X and Yvalues of B (Ex: Line(1,2,3,5))
2) To trace a circle :
:Circle(X,Y,r)............................To trace a circle, and the center has X and Yvalue of (X,Y) and the rayon is r (Ex: Circle(5,6,3)
3) To trace a vertical line on all the screen :
:Vertical X........................To trace a vertical line, and its Xvalue is X (Ex: Vertical 7)
4) To trace an Horizontal line on all the screen :
:Horizontal Y............To trace an horizontal line. its Yvalue is Y (Ex: Horizontal 5)
5) To draw something :
You must use the Pen command. but this command connot be used in a program.

The asm lessons are in english. I put here the most comprehensible et useful help to learn asm programmation. You need only one of this lessons to learn asm but if you want to use all yout TI's fonctions, you should read a lot and work more you can imagine.
If you have or find another lessons, send it to me, it will help other people who want learn asm.
