Hmm.. Robert, I am not sure why you would have to create the array and then
put the strings in it then pass
the array (ok, I agree that is what is really going to happen...but you can
hide it)

with Ada.Strings.Unbounded;
with Text_IO;

procedure AnotherWay is

  function "-"(Item : in String) return
Ada.Strings.Unbounded.Unbounded_String renames
Ada.Strings.Unbounded.To_Unbounded_String;
  function "-"(Item : in Ada.Strings.Unbounded.Unbounded_String) return
String renames Ada.Strings.Unbounded.To_String;

  type Unbounded_String_Array is array (Integer range <>) of
Ada.Strings.Unbounded.Unbounded_String;

  procedure Something (Data : in Unbounded_String_Array) is

  begin
    for I in Data'range loop
      Text_IO.Put_Line(-Data(I));
    end loop;
  end Something;

begin

  Something((-"Hello", -", I'm", -" the function"));

end AnotherWay;


Now, having said and done this....I agree with Robert that this is not a
normal Ada idiom
so the original poster should really think about whether or not you want to
do this.
While the code I provided above will actually work, it is really a bad idea
so if
you can look at your problem space in a different manner, I would really
recommend
against doing this.


Also one more note, the original post talked about writing a function to do
something but the example
(in the original post) was actually a procedure.
