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 Œ ) 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 ".
