Save
    ---------------------
    Different to basic
     
     
    Use: Used to save data.
     
    Example: FileName$=Save(Window:Icon$,LeafName$,FileSize%,FileType%)
     
    Where: Window:Icon$ is the icon to drag. LeafName$ is the leafname
    (the writable icon in SaveAs window), FileSize% is size of the file and
    FileType% is of course the filetype to be used.
     
    When a drag event is received for the icon, 'Icon$' you can do: Save
    Window:Icon$ which will start a drag event. When the user drops the
    icon, WimpBasic will work out which file the data should be saved in.
