Applications created with MSG-IDE and TRAN-IDE require minimal developer coding. Instead, developers can develop an application using the graphical user interfaces to select and build the objects.
Because applications created with the IDE tools are event-driven, each event provides the developer with an opportunity to take control of the application using the ODL code contained within custom functions and using distributed function calls (DFCs) to talk to other applications.
Some event triggers are hard-coded into application objects and always occur at a specific point in the application, while other objects occur based on user interaction with the application. The ODL code within custom functions determines how your application responds to these events and how control flows between application objects.
There are also functions—such as initialization and deinitialization—that are not triggered by events, but are called at predetermined points. You can also use these functions to control an application.
