The Outline view displays an outline of the program listing that is highlighted in the Program Listing area and lists the structural elements of the program as nodes in a tree view. The Outline view contains a top level node for each main section of a program. For example, a COBOL program in the Program Listing area shows the four divisions of the COBOL program in the Outline view when you first open the program. For an Assembler listing, the Outline view shows all the top-level nodes.
When multiple programs are open in the Program Listing area and you click the tab showing the name of a program, the Outline view refreshes to display the relevant items associated with the selected program.
