Accessing Prompted-Worksheet Variables
After you access a worksheet, press # or " to select variables. For
example, press & \ to access the Amortization worksheet, and
then press # or " to select the amortization variables (P1, P2, BAL, PRN,
INT).(See “TVM and Amortization Worksheet Variables” on page 22.)
Indicators prompt you to select settings, enter values, or compute results.
For example, the i# $ indicators remind you to press # or " to select
other variables. (See “Reading the Display” on page 2.)
To return to the standard-calculator mode, press & U.
Types of Worksheet Variables
• Enter-only
• Compute-only
• Automatic-compute
• Enter-or-compute
•Settings
Note: The = sign displayed between the variable label and value
indicates that the variable is assigned the value.
Enter-Only Variables
Values for enter-only variables must be entered, cannot be computed,
and are often limited to a specified range, for example, P/Y and C/Y. The
value for an enter-only variable can be:
• Entered directly from the keyboard.
• The result of a math calculation.
• Recalled from memory.
• Obtained from another worksheet using the last answer feature.
When you access an enter-only variable, the calculator displays the
variable label and ENTER indicator. The ENTER indicator reminds you to
press ! after keying in a value to assign the value to the variable.
After you press !, the indicator confirms that the value is assigned.
Compute-Only Variables
You cannot enter values manually for compute-only variables, for
example, net present value (NPV). To compute a value, display a
compute-only variable and press %. The calculator computes and
displays the value based on the values of other variables.
