I used this code

:Plot1(Scatter,X,Y,.

:∟X→P:∟Y→Q

:Repeat getKey or S<2

:∟P→X:∟Q→Y

:DispGraph

:DelVar ∟PDelVar∟Q1→S

:For(X,min(∟X)-1,1+max(∟X

:For(Y,min(∟Y)-1,1+max(∟Y

:sum(1=max(abs(∟X-X),abs(∟Y-Y

:3=Ans or 3=Ans-max(∟X=X and ∟Y=Y

:If Ans:Then

:X→∟P(S

:Y→∟Q(S

:S+1→S

:End:End

:End:End

:PlotsOff

:ClrHome:"

(Which was written by DarkerLine) on my ti83+ calculator. I wasn't sure how to make LX LY LP and LQ, so I replaced them with L1 L2 L3 and L4, respectively. This provided an err:invalid dim message, so I changed the window dimensions to 94 by 62, as the main thread calls for (http://tibasicdev.wikidot.com/game-of-life). Now I get an err:window range, and when I do goto it brings me to the displaygraph function. any idea what is going wrong?
