Built-in Variables
Built-in variables are settings that are frequently needed in CXL scripts. Each built-in variable must be typed in upper case exactly as shown so that they are recognized as special variables. Built-in variables that have a default setting only need to be set if you need a different setting for the purposes of a particular script. If not set by the user, they will have the default value. Built-in variables that have no default will be automatically set, and should not be set by the user.
