In my experience, it kind of depends on the situation. There's no one
right answer.
If you have to do a _lot_ of DmWrites, for instance, to update
several different discrete byte ranges, then maybe deleting and
creating a new record makes sense. It's simpler, easier, and more
straightforward code. If you are buffering all the new data in a
struct and can just blast it into the existing record, and it'a all
the same size, DmWrite works fine.
There are no other wildly relevant functions, except there is one Fld
function that lets you update a record in place, from a field's text,
as long as you are only doing that with one field. The technique is
described in the Rhodes/McKeehan book.
