■
Receive notice of incoming packages  
Either a SCREEN COBOL program unit or a user-written server can be notified 
when a package arrives. The process that delivers the package notifies a SCREEN 
COBOL program by calling it or notifies a server by issuing a SEND to it. You can 
have different program units or servers receive notifications under different 
conditions.  For example, you might write one program unit that displays a 
notification message and another that immediately files a package for later retrieval. 
The application determines which program unit to invoke.
■ Perform administrative and management functions 
A SCREEN COBOL program unit can issue requests to TRANSFER servers for 
administrative services such as registering a new correspondent and for management 
services such as monitoring the delivery system. 
With the ADMIN and TMANAGER applications provided by Tandem, you do not 
need to write your own software to run your system. ADMIN lets administrators 
perform administrative tasks for correspondents, interest groups, distribution lists, 
folders, and the TRANSFER system. TMANAGER allows system managers to 
monitor and manage a TRANSFER delivery system.
Figure 1-3 shows the parts of a TRANSFER application.  In this example, the 
application includes servers to manage its own database, as well as TRANSFER servers 
for package assembly, filing, and delivery.
