I have a question I can'f figure out.  If I have the following code:

  type My_Type is (obj1, obj2 obj3, obj4, obj5, obj6);
  subtype My_Subtype is My_Type range obj1 .. obj4;

My question is, I need a new subtype that ranges from obj4 to obj1.
Will the declaration

  subtype Second_Subtype is My_Subtype
          range My_Subtype'last .. My_Subtype'first

do that?  If not is there a way to do it without defining a new
enumeration?

The type would be used in a loop that loops through the enumeration
objects using S'succ(S).

TIA,
chad
