Uniface application resources are the runtime objects, HTML files, images, and other files that make up an application.
Runtime objects are compiled components, application shells, libraries of global objects, signatures, and definitions that can be interpreted by the Uniface runtime process. They are generated from development object definitions during compilation, and can be packaged into Uniface archive files (UARs) for deployment.
Uniface looks for application resources in the locations specified in the [RESOURCES] section of the application assignment file. These locations are referred to by the $RES logical path.
The Uniface archive USYS:usys.uar is always one of the resource locations because it is included in the [RESOURCES] section of the usys.asn file that all applications use.
