LVUSE     GuiFile GadID

    Select another listview and make it the CURRENT LISTVIEW.

    A ListView becomes CURRENT when the user clicks on a line.

    You can thereafter change the Current listview with this 
    command :

        LVUse MyGui.gc 1

    This is an important command, because most of the  other 
    ListView commands will act on the CURRENT LV, and this is 
    the command that can set or change it.
