The Variables "I" and "J"

There are two variables that you can access directly: the variables I and J. Although they store values as other variables do, I and J are special in that they can be used to refer to other variables, including the statistical registers, using the (I) and (J) commands. (I) is found on the key, while (J) is on the key. This is a programming technique called indirect addressing that is covered under “Indirectly Addressing Variables and Labels” in chapter 14.
