   Code:
   '-- This sample Avenue code demonstrates how to use the
   '-- Palette.MakeFromFile request with ODB files that have
   '-- palettes as the first object.
   
   "$AVHOME/symbols".asfilename.setcwd 
   newFileName = filedialog.show("*.avp","ArcView Palette Files (*.avp)","") 
   if(newFileName = nil) then 
     return nil 
   end 
     
   testodb = odb.open(newFileName) 
   firstobject = testodb.get(0) 
   if(firstobject.is(Palette)) then 
     newPalette = Palette.MakeFromFile(newFileName)  
   end

   
   
3. Compile and run script.
