VARIABLE

A variable stores a value which can be used throughout the script as a parameter of commands. Instead of writing the value directly into the script, you first define the value as a variable and then use this variable name to reference its value. To store and reuse the result of an expression at the script level, you must define variable and then reference it within an Expression as @VariableName.
