Input links appear with a connection node on the left side and output links appear with a connection node on the right side. Linking a record requires that the linkage tool be selected. A multi-point wire will can be drawn between any two linkable nodes on the screen. Each time the left mouse button is hit, a new bend will be introduce on the wire. The wire is terminated by hitting the middle mouse button.
Links have attributes which can be modified with the examine tool.
When the examine tool is selected and mouse is depressed anywhere on a connection wire, the user can select the edit attributes option. Records contain attributes which can also be modified using the examine tool. A dialog box will appear showing all the fields of a record which can be modified. The current values are shown and can be modified by selecting the edit box and typing a new value. A macro definition can be entered for any field, including menus and links.
