In this lesson, you'll use a variable 'in the background' to move a character. Rather than seeing the value of the variable printed, the variable is used in place of a number in .setCursor. Anywhere that there is a number in code, you can replace it with a variable.
It wouldn't be much use here, but you could make the 'row' number in the .setCursor() method a variable instead of a 0. To understand how that works, try it.
Declare the variable by typing it's 'type' (int) and then it's name (row may be a good name). Then give it an initial value, just like you did with position. Now replace the 0 in .setCursor() with your variable and upload.
Everything should look the same, but you'll have a better understanding of how to create and insert a variable.
