If the view code is empty, it is used to enter a Web address in order to display the corresponding page in the frame. This Web address can be any URL or a UNC path accessible via the Web or on an internal server. But this can also be linked to a directory on the client workstation, when in client-server mode (the directory list can be displayed, and it is possible to double-click on the tables it contains).
For example, the following values can be entered "http://www.sage.com", or "C:\temp\my_file.htm", or even "\\my_server\my_home_page.pdf"
