Yes they are. Names are just short-cuts to indexes. Named parameters use "the first unused index." You then set an explicit index that is already in use. Each index can only have one name, so it is over-written with the last-used representation. To avoid such problems, it is strongly advised you do not mix parameter types. Either use bare parameters, explicit indexes, or names-- but pick one and stick with it. -j -- Jay A.
