Storing Data into Variables 3-5
Example:
In this example, we store 3 in C, 4 in D, and 5 in E. Then we view these variables
via the VAR Catalog and clear them as well. This example uses RPN mode.
Note the
and annunciators indicating that the Ø and × keys are active
to help you scroll through the catalog; however, if Fraction Display mode is active,
the and annunciators will not be active to indicate accuracy unless there is
only one variable in the catalog. We return to our example, illustrating how to
navigate the VAR catalog.
While we are in the VAR catalog, let’s extend this example to show you how to
clear the value of a variable to zero, effectively deleting the current value. We’ll
delete E.
Suppose now that you wish to copy the value of C to the stack.
Keys: Display: Description:
(
)
Clear all direct variables
C
D
E
Store 3 in C, 4 in D, and 5 in E.
u()
Enter the VAR catalog.
Ø
Scroll down to the next direct
variable with non-zero value: D=4.
Ø
Scroll down once more to see E=5.
E is no longer in the VAR catalog,
as its value is zero. The next
variable is C as shown.
The value of C=3 is copied to the
x-register and 5 (from defining E=5
previously) moves to the y-register.
