Yep, I'm getting more careful about not running after wild geese.

When you post the transaction will be Commit'd (if possible) but if not
possible a SavePoint will be generated. (which is like a commit retaining).
When the last dataset to be in an edit state is posted a Commit will happen
if possible.

Calling Commit means that all other datasets in an edit state must be posted
as well.

Somewhere there is a really great article about all of this stuff. Look in
the help file and the TI articles and the FAQ.
