S := new Node'(Next => S,
               Item => <<a function padding Val to 50 characters>>,
               Len => Val'Length,
               Count => 1);

If S is null then it can do no harm to assign it to the new node's
Next field.

You might consider replacing Item and Len by a bounded string of
length up to 50.
