Once the deck is loaded, there is no requirement to load additional data. A deck is a self-contained
set of elements or user functions. The user function presumes that the cards, which are read, are
related to the deck in memory. This is beneficial where there are suspend and resume modes.
WML decks are helpful in the following ways.

 Showing content
 Providing selections
 Local area checking
 Easy scripting tasks

 Routing to other decks and Servlets

Task How are WML decks helpful?
