Library's provide a convenient means of storing
client-side program units and sharing them among multipule
applications. Once you create a library, you can attach it
to any other form,menu,or library modules. When you can call
library program units from triggers menu items commands and
user named routine, you write in the modules to which
you have attach the library.
when a library attaches another library ,program units in
the first library can reference program units in the
attached library. Library support dynamic loading-that
is library program units are loaded into an
application only when needed. This can significantly
reduce the run-time memory requirements of an applications.
