Storing a value
in a variable
You can save an answer in a variable and use the variable in
later calculations. There are 27 variables available for storing
real values. These are A to Z and θ. See Chapter 11,
“Variables and memory management” for more information
on variables. For example:
1. Perform a calculation.
45>@8 >[8@3
>(17(5@
2. Store the result in the A variable.
>$/3+$@A >(17(5@
3. Perform another calculation using the A variable.
95>@2>;@>$/3+$@A
