The application's main executable file (that is, the file that is invoked to start the application) should contain those object modules which are required to execute the application, and that do not contain generic routines or generic Presentation Manager resources.
Where it is envisaged that an application object is usable only by the current application, and has no possible potential for future reuse, it may be bound with the application's main executable file. However, if such potential for reuse exists, the application object should be placed in a dynamic link library.
