The Application Diagram provides a graphical view of IBM® i native applications. There are two different diagrams that you can look at in the Application Diagram view: a Source Call Diagram and a Program Structure Diagram. The Source Call Diagram takes ILE RPG, ILE COBOL, and ILE CL source as input and displays a call graph showing subroutine, procedure, and program calls. The Program Structure Diagram takes program and service program objects as input and displays the binding relationships between them as well as the modules bound into each program and service program.
