That's an empty string.  In any case, if you really want to call it a
null string, that's fine, just a little more likely to be
misinterpreted.  NULL is neither number nor string, it is null.  $b (per
the example above) is null.  It is not the null string, it is not undef,
it is not zero, and you do not get $200 for passing GO.
