Variables

What is a variable?

The variable. You couldn't do crap if these weren't around.

A variable is a letter that means something else. As in, 'A' equals 9 OR A=9. There are so many uses for variables. If you want something to move on the screen, you need them.

To create a variable (if you have done nothing on the calc. and used no games or programs, all the letters are equal to 0) you need to select which letter you want to use.
I'll use 'A'.
If I want A to equal 5, I do the following:
Select the letter 'A' using ALPHA.
Selecting the Sto-> button from the left-bottom corner of the calc.
Select '5'.
If done right, it should look like this:

A->5

Press enter. 'A' should now equal 5.

This can be used to output something on the homescreen. Say you want to put the work 'hi' at 5 and 8. Store 'A' as 5, and 'B' as 8, then put them in an output(:

Output(A,B,"Hi

Now, once you have learned to substitute numbers with variables, you can make things move on the screen.
Make this program on your calculator:

A->5
B->8
Output(A,B,"O
Pause
Clrhome
B-1->B
Output(A,B,"O

What just happened is this. You stored the numbers as the letters, then outputed them on the screen. You then paused, causing it to clear the homescreen when you pressed enter. Then, 'B' was subtracted by 1, changing it to 7. You then outputed it again, only this time, it is one space to the left.
