As you work in a PocketBuilder target, the objects you create are stored in one or more libraries (PKL files) associated with the application. PKL files are similar to PBL files associated with PowerBuilder applications. When you run your application, PocketBuilder retrieves the objects from the library.
PocketBuilder provides a Library painter for managing your libraries. For information about creating a new library and working with libraries in the Library painter, see Chapter 4, “Working with Libraries.”
