         "Title/Label - Save-as-file"
    If title is blank, then we just use 
          "Untitled" or 
          Save-as-file

Input Parameters:
   h_win     : The handle of the window widget
   lbl       : The label/title of the design-time window record
   lbl-sa    : The label/title string attributes.
   save-file : The file name (or ? if UNTITLED).
