You don't have to use an ADT. You could just use an array:
subtype Set_Element is Integer range 1 .. 100;
type Set_Type is array (Set_Element) of Boolean;
Then "set iteration" is just iteration over the array:
for Element in Set_Element loop
if Set (Element) then
<Element is in set, do something with it>
end if;
end loop;
Will that do?
