This is not a generic.  Generics begin with the word "generic".  Therefore, you can't instantiate it.

It looks like you want to make this a generic and you want the generic type parameter to be called Value_Type.  Try this:

   generic
      type Value_Type is private;
   procedure Swap_Generic (Value1, Value2 : in out Value_Type) is 
      Temp_Value : Value_Type; 
   begin -- Swap_Generic 
      Temp_Value := Value1; 
      Value1 := Value2; 
      Value2 := Temp_Value; 
   end Swap_Generic; 

                               -- Adam
