Questions about the OLE automation VBA command Prism.Quit

A dialog comes up asking if the changes are to be saved

The Prism.Quit command will bring up the dialog about saving changes if Prism has any unsaved open project.  To avoid this dialog, use the Close command within the Prism script to close the project. If all projects are already closed, the VBA Prism.Quit command will simply quit Prism and ask no questions.

The command doesn't work. Prism doesn't quit. 

Make sure you have the syntax right. The command must be entered like this:

   Prism.Quit

This syntax, with extra parentheses, does not work:

   Prism.Quit()
