I have a bit of legacy code in my system that I am trying to remove
all warnings from.

The package is a generic -- with:

type Element is (<>);
type Element_List is array (Indexing range <>) of Element;


I have been stumped by one compiler warning where one of the functions
needs to return a zero-length empty generic array:

warning: variable Result_String is read but never assigned

code:

if Error_Condition then
  declare
    type Result is new Element_List (Indexing.First + 1 ..
Indexing'First);
    Result_String : Result;
  begin
     return Element_List (Result);
  end;
end if;

How do I initialize this array when I can't know what type it is or
will be?

Thanks
