TI-83--Programming a Pong Game

Hey, I'm programming a Pong game for the TI-83; I'm used to programmming, but new to TI-BASIC. I have the following line of code, which the TI-83 says has a syntax error:

If D<0
Then
If R=2
Then
Rü3
End
If R=4
Then
Rü1
End
End

(the ü is the -> symbol)
The error appears at D<0
Is the error the Statement itself? If not, please tell me so I can be certain that I must look further back in order to fix the code. Please reply soon.

i don't see anything wrong..i'd just retype it to make sure that there isn't some petty little mistake that you have made... that often helps me....
anyway, i'm not quite sure but i'd look at the line above If D<0 just to make sure that it follows correctly, to make sure that some command doesn't need to ended or something.

oh, its acturelly preetty simple

you should do
3->R
nor R->3
cuz the calc will read it as if u r trying to store R as varrible 3, but numbers canot be variable.
=)

where do you get nor in the 2nd row??? (im in elementry and my sister dont need the calculator)

i think he meant not
as in "do not do this 'R->3'"
notice that the "t" is right next to the "r" on the keyboard
accidents happen

Alright, but what is the full code? I like this site btw. lol

Blast from the past, eh? I'll do a little looking and see if I can find you one of my old pong programs. Haven't done programming with TI Basic in a long time, so it may take a bit to find the code.

Thanks Bro. I really get bored with those overly simple games. like BlackJack, or snake. lol
