User defined global variables and universal constants generally accessible in a Map Document, freely applicable in definition queries across different layers (or in other expressions), allowing user to easily and simultaneously control multiple layers’ appearance by simply modifying the value of the shared variable.
 
Example:
continent = 'Africa'  # global variable
Layer A Definition Query: "CONTINENT" = continent
Layer B Definition Query: "CONTINENT" <> continent
