I'm new to this forum, but I have a question. I'm trying to make langton's and on my ti-84 +C silver, but whenever I start my code it sets y to 1 automatically. Even though I had just set it to 82. It's really weird.

This is my code:

:AxesOff

:ClrDraw

:132→x

:82→y

:1→D

:Repeat 0

:If pxl-Test(y,x

:Then

:D-1→D

:Else

:D+1→D

:End

:Pxl-Change(Y,X

:If D=5

:Then

:1→D

:End

:If D=0

:Then

:4→D

:End

:If D=1

:Then

:Y-1→Y

:End

:If D=2

:Then

:X-1→X

:End

:If D=3

:Then

:Y+1→Y

:End

:If D=4

:Then

:X+1→X

:End

:End
