The short answer is No - there is no way to save data without using an 
external file of some sort. The external file can be a text file or it 
can be a stack that is stored as a separate file rather than being 
built into your application. In OS X this still looks neat as you can 
hide the data stack inside the OS X bundle.

A common way to achieve this is to make a splash-screen application 
where the mainStack is just a splash screen or static display and all 
data is entered on sub-stacks. When building, check the option to save 
sub-stacks separately and they will remain as separate files which can 
be saved to store any new data. The actual application (the mainStack 
and the Rev engine) is read-only so no changes can ever be saved to it.

The only thing to be wary of is that if the data is crucial, it should 
perhaps be stored in the user's documents folder rather than with the 
application. If it is preference data, it should be stored in the 
Preferences folder. The user should be able to delete the application 
and re-install without losing data!
