For general help on the Ada language, it is better to ask on the USENET
newsgroup comp.lang.ada.

By the way, the name of the language is spelled "Ada". It is not an
acronym, so don't write it in all-caps.

Yes, but the discriminant must have a default value, for example as in

   type Rocket_Type (Liquid_Fuel : Boolean := False) is
   record...end record;

   type Rocket_Type (Liquid_Fuel : Boolean := False) is record
      (declare some components that do not depend on the discriminant)
      case Liquid_Fuel is
      when False =>
         (declare some components for rockets with non-liquid fuels)
      when True =>
         (declare some components for rockets with liquid fuels)
      when ...
      end case;
   end record;

Read a book about Ada, for example the Wikibook at
http://en.wikibooks.org/wiki/Ada_Programming.
