What is the advantage of the library?
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
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 applications.
