Assembly 3D Grapher for the Ti-83

        A3Dgraph is a simple 3D graph written in assembly.  It can't do much besides make a 3D graph that stays put.  This version currently has its input in basic, but I will change that.  It also uses the user variables X,Y and Z because nothing else besides the op family will do this correctly for me.  If someone can tell me how to store negatives another way please do.  Also if someone else can tell me how to parse an equation not stored to a user equ (Y1,Y2..) or String please email me telling me how.


How to use:
        When you run the calling program, A3DGRAPH, it will ask for Y.
  input the equation like you would on the graph screen with the additional variable of Z.  For interesting results include sin or cos.
	Ex:  Y=sin(X+Z), Y=X^3+Z, or Y=2
When it stops graphing push a button and it should leave.


Specialties (Bugs):
        -cannot use rand or lists
        -can get rather ugly if lines are too close together
        -can stop it just by pressing on 
		-this may not be a bug, but I don't know why it does this.
        -negatives may bounce of the wall
                -don't understand this either
		-I think I fixed this, but I'm not sure
        -square roots usually don't work (can't graph complex numbers)
	-doesn't work with Virtual Ti, but does with my calculator and CalcEm


Future Ideas:
        -make it all in assembly
        -make it spin  (Lord help me with this)
        -make it quicker
	-make it smaller


Version History:

        ver 1.0 - The first version.  Not much to say about it.  
                  Rather slow for assembly.


Thanks to the following:
        -Chris Brainerd-His Basic program I changed to take out the Matrices and then took that and converted it to assembly.
        -Every Body Who gave out their source code.
