What are the advantages of libraries?
Libraries provide a convenient means of storing client-side program units and sharing them among multiple applications. Once you create a library,you can attach it to any other form,menu or library ,module. Then, you can call library units from triggers, menu item commands and user-named routines you write in the modules to which modules to which you have attached the library. When a library attaches another library,program units in the first library can reference program units in the attached library. Libraries support dynamic loading-that is, a librarys program units are loaded into an application only when needed. This can significantly reduce the runtime memory requirements of an application.
