## Data persistence

When you work with an app, you enter data of one sort or another, such as definitions of functions, window settings, and
preferences. The app records all this data and automatically saves it for you. If you leave the app and come back to it later,
all that data is still there. In fact, you can save an instance of the app with a new name and keep the original version for
another purpose. The new version, under the new name, contains all the data from the source app. (This is explained in
"Creating customized apps" on page 46.)
