To make any variable persistent throught your application: 

* ''after you are logged in'', you have a session going 
* on any page you can do: 
    tk::session::setAttribute -name HOME -value "/home" 


* and to access it from any other page you do: 
      set home [tk::session::getAttribute -name HOME]
