Lesson 13: Creating (Naming) Variables
To name an object 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 letter—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:
m From the stack, use (STO).
m From the Variable Browser, use HEM
The following two examples illustrate each method.
Example: Find the square root of 2 and store the value in a variable
named ¢/ (using (STO)).
Step 1: Clear the stack and find the square root of 2.

Step 2: Enter the name 11.

Step 3: Store the object (Level 2) in the name (Level 1). It
disappears from the stack.

Step 4: Check your current variable menu to confirm that #1 is
stored. Notice that the names in the menu are displayed in
upper-case for legibility.
