Well, TMemDataset is officially 'maintained' but in practice it didn't
had any updates for years. The main idea is to let TBufdataset replace
TMemDataset. But as long that is not possible... maybe I should have a
look at TMemDataset.

Secondly I've never cared about alignment in the db-units. More an more
people are using it on ARM-based machines, though. And I recieve more
and more reports about problems. So I'll have to look into the

Yes, it should. But only if the 'dataset' already exists. This is
clearly never the case with a TMemDataset. (Unless you read it from
disk, for example)

So I'm not sure what to do here.
