Indirectly Addressing Variables and Labels
Indirect addressing
is a technique used in advanced programming to specify
a variable or label
without specifying beforehand exactly which one
. This is
determined when the program runs, so it depends on the intermediate results
(or input) of the program.
Indirect addressing uses two different keys:
(with
) and
(with
f
).
The variable
I
has nothing to do with
or the variable i. These keys are
active for many functions that take
A
through
Z
as variables or labels.
i
is a variable whose contents can refer to another variable or label. It
holds a number just like any other variable (
A
through
Z
).
is a programming function that directs, "Use the number in i to
determine which variable or label to address."
This is an
indirect address
. (A through Z are
direct addresses
.)
Both
and
are used together to create an indirect address. (See the
examples below.)
By itself,
i
is just another variable.
By itself,
is either undefined (no number in
i
) or uncontrolled (using
whatever number happens to be left over in
i
).
The Variable "i"
Your can store, recall, and manipulate the contents of
i
just as you car, the
contents of other variables. You can even solve for
i
and integrate using
i
.
The functions listed below can use variable "
i
".
