Defaults for Global Variables may be viewed and over-written on the Global Variables tab of the map setup window.
When selecting the Global Variables tab of the map setup window all global variables are displayed to the user, along with their defaults.
To over-write a default value, select the required variable and enter the new value. The variable name will then be shown in blue, along with the new value.
To reset an over-written value, select the variable to be reset and select the clear map variable button. This button is only available for variables that have been over-written at a map level.
