If you're talking about doing this in a standalone, whenever you 
implement the "save stack <stackName>" command, all changes are written 
to disk at that time to the stack you've identified. Until then, the 
changes only reside in memory and will be disposed of when your app 
closes. Of course, a lot of this depends on the construction of your 
application - for example, suppose you had an Address Book with a 
single stack as an interface to the user to display the addresses. You 
could construct it so that the stack that showed the interface 
maintained each card for each person, and changes made are saved to 
that stack. On the other hand, you could store the data in a database 
or text file, and have only a single card as your interface to the 
user, drawing the data from the database/file and parsing it to get the 
right "record" to display.
