I have been unable to find anything in the help files regarding this,
so here goes:

For TIBOQuery.CommitAction = caFetchAll is there any way to limit the
maximum number for rows fetched when Commit is called? There is
TimeoutProps.AttemptMaxRows but that would seem to only apply when IBO
is attempting to automatically commit a transaction. Does this
property also apply when explicitly commiting a transaction?
