The Variable "i"

There is a 27th variables that you can access directly–the variable i. The

Œ

key is labeled "i", and it means i whenever the A..Z annunciator is on.
Although it stores numbers as other variables do, i is special in that it can be
used to refer to other variables, including the statistics registers, using the (i)
function. This is a programming technique called indirect addressing that is
covered under "Indirectly Addressing variables and labels" in chapter 13.
