Another Psuedocode Implementation Question?

Hello there. I have another psuedocode problem. The following photo shows the section of the psuedocode that has me stumbled. The thing is that when I try to execute this part of the entire psuedocode, it says that the gameOn function is undefined. Why is this? Can anyone help out?

Here's my attempted psuedocode implementation:

while gameOn == true
    if turn < 0
        [r,c] = getmove(G,-1);

You failed to do steps 4 and 6 and 7. gameOn is defined in step 6.

I'm sorry, here is the rest of the first half of the code. Matter of fact, here's the other half of the psuedocode as well.

G = [0 0 0, 0 0 0, 0 0 0];
turn = 1;

rand(5)

if rand < 0.5
    turn = -1;
end

gameon = true;

plotTicTacToe(G)

while gameOn == true
    if turn < 0
        [r,c] = getmove(G,-1);

[Walter Roberson]

You set gameon to true, but you compare gameOn to true.

[Matt Amador]

So then should I just leave the while as:

while gameOn

As long as you make sure you initialize gameOn (upper-case O) instead of gameon (lower-case O) either one is fine.
