1-6 Creating and Using Variables

This section explains how to create a new variable (user variable), and provides a simple sample calculation
that illustrates how to use a variable.

Creating a New Variable

The most common way to create a new variable is assigning a value or expression to the applicable variable
name. Use the variable assignment key (W) to assign data to a variable.
The following is an example of assignment to a variable while "main" is specified as the current folder.
Example: To create a new variable named "eq1" and assign the expression 2 + 1 to it
The following assumes that there are no variables named "eq1" or " " currently in the "main" folder.

in this example), and assigns the expression 2 + 1 to it.
