Thanks for the link. As far as can be told from this, dbase hasn't got
nulls at all -- is that correct, or are they just omitting a ton of
relevant information?
It looks to me like we should just remove the special case for integer
fields altogether. The special case for date fields is wrong in detail
as well: as coded it will accept "date" fields with a leading sign,
which surely is not intentional.
