Lesson 13: Creating (Naming) Variables

To name an ol)ject is to create a global variable. You store an object

in user-memory

by giving it

a name. You can

use descriptive names

for variables. A name can be as short as one lettei'—or as long as

127. Global variable names can’t be identical to the names of built-in

commands and can’t begin with a number.

There are two ways to create a new global variable:

■ From the stack, use fSTO).
■ From the Ahriable Browser, use

The following two examples illustrate each method.

Example:

Find the square

root of 2

and

store

variable

named

Clear the stack and find the square root of 2.
