                                    AES


The Application Environment Services (AES) compose the highest level of
the operating system. The AES uses the VDI, GEMDOS, and XBIOS to provide
a global utility library of calls which provide applications with the GEM
interface. Usage of the AES makes application development simpler and
makes user interfaces more consistent. The services provided by the AES
include:

   ° Application Control/Interaction
   ° Event Management
   ° Menu Services
   ° Object Rendering/Manipulation
   ° Form Management
   ° Graphic Utility Functions
   ° Scrap (Clipboard) Management
   ° Common Dialog Display
   ° Window Management
   ° Resource Management
   ° Shell (Desktop) Interaction

System-specific AES information and variables may be determined through
reserved fields in the application's global array (see appl_init()) or by
using the various modes of appl_getinfo().
