Or simply write:

  C : Character
  Word : Unbounded_String;
begin
  loop
    Get_Immediate (C);
    if Is_Graphic (C) and C /= ' ' then
      Append (Word, C);
    else
      Process (Word);
      Word := Null_Unbounded_String;
    end if;
  end loop;
exception
  when End_Error =>
    if Word /= Null_Unbounded_String then Process (Word); end if;

as was recently posted on thread "parse word from a string" ;-)
