Each PersistentObject has a unique long key.

Import the following classes:
- net.rim.device.api.system.PersistentObject
- net.rim.device.api.system.PersistentStore
- java.lang.String
- net.rim.device.api.ui.component.Dialog
To create a unique long key, in the BlackBerry® Integrated Development Environment, type a string value.
```
com.rim.samples.docs.userinfo
```
Right-click the string and click Convert ‘com.rim.samples.docs.userinfo’ to long.
Include a comment in your code to indicate the string that you used to generate the unique long key.
To create a persistent data store, create a single static PersistentObject and invoke PersistentStore.getPersistentObject, using the unique long key as a parameter.
```
static PersistentObject store;
static {
store = PersistentStore.getPersistentObject( 0xa1a569278238dad2L );
}
```
