How do I execute an initial Framework level command when starting up a Framework application

How do I execute an initial Framework level command when starting up a Framework application?   

If you want to execute a specific command when a Framework starts, refer to New UF_SYSTM IIP (Imbedded Interface Point) methods that you can override (Windows) and the SwitchCommand parameter in Web Application Start Options (web).

Note that the concept of a default command at the Framework level has no meaning.
