Nestor,
I don't think it is like a link list.
In a link list you can search for an element.
Also you can traverse a link list back an forth.
All these are not possible in an enumeration.
In an enumeration you can traverse through it only once and only
in the forward direction.ie. you can only point to the next element and not to the
previous element.
hope that answers your query.
Regards,
Tushar
