Where am I?
Sometimes it is useful to know how you arrived at a particular workspace. For example, queries or processes might be driven silently to derive the data that is being displayed. The SHOWNAV or WHEREAMI commands display the current internal navigation trace table in a scrollable popup window. The table provides a history of the workspace navigation and the variables that are involved in arriving at the current workspace.
Use the HOME command to return to the first workspace in a navigation chain . Returning to the first panel resets the navigation trace. Use the RESETNAV command to reset the trace table from the current workspace.
