Defines a global variable that will be available in all catalogs with the notation @@Variable@@. Variable identifiers must begin with a capital letter, and can contain only word characters (A-Z,a-z,0-9 and underscore) -- they are case-sensitive. If using the ParseVariables directive, only variables in ALL CAPS will be parsed. These are substituted first in any MiniVend page, and can contain any valid MiniVend tags including catalog variables.
