        Component-Selection windows
        The windows for creating or modifying components often (but not always) come in pairs. In the first window, the Component-Selection window, you can create a component or select an existing component to modify. You can also view notes and copy, delete, or print information about a component. In the second window, the Component-Definition window, you can make changes.
        Component-Definition windows
        After you select a component to create or modify and click OK in the Component-Selection window, you typically see the Component-Definition window. From the Component-Definition window, you can enter, edit, or delete values or items that describe the component.
        Load Job and Unload Job windows
        The Load Job and Unload Job windows provide a visual presentation of the basic components that you choose for each job.
        Views windows
        A Views window shows a graphic representation of the relationships among various ipload components. From a Views window, you can search for specific components, select an existing component for editing, or create a component.
        Selection-List windows
        A Selection-List window lists the possible values for a text box. A down arrow that follows a text box indicates that you can use a selection list to see and select possible values for the text box. When you click the down arrow, the corresponding Selection-List window appears.
        Message windows
        A message window typically contains either a warning or an information update. A warning lets you verify or cancel the action that you have chosen. An update informs you about the successful completion of an operation or explains why an operation failed.
