Entering and Displaying Data

The calculator's variables are used to store data input, intermediate results,
and final results. (Variables, as explained in chapter 3, are identified by a
letter from A through Z or i, but the variable names have nothing to do with
program labels.)

In a program, you can get data in these ways:

From an INPUT instruction, which prompts for the value of a variable.

(This is the most handy technique.)

From the stack. (You can use STO to store the value in a variable for later

use.)

From variables that already have values stored.

From automatic equation prompting (if enabled by flag 11 set).

(This is also handy if you're using equations.)

In a program, you can display information in these ways:

With a VIEW instruction, which shows the name and value of a variable.

(This is the most handy technique.)

On the stack—only the value in the X–register is visible. (You can use PSE

for a 1–second look at the X–register.)

In a displayed equation (if enabled by flag 10 set). (The "equation" is

usually a message, not a true equation.)

Some of these input and output techniques are described in the following

topics.

Using INPUT for Entering Data

The INPUT instruction (

a

Variable ) stops a running program and

displays a prompt for the given variable. This display includes the existing
value for the variable, such as
