MARK
Stores the current datarow state for a later recall. Markpoints from different sources can be nested. Marking does not change the user datasource. -
ADVANCE
Requests that the datasource should be moved to the next row. An advance operation does not change the current cursor position. The cursor is not moved until a 'COMMIT' operation has been reached. Repeatable sections will perform an auto-commit based on the group in which they are in. -
RECALL
Recalls a marked position. -
NO_OP
Do nothing. -
DONE
Finishes (and closes) the currently open context. If the last mark has been closed, the datasource is also closed. If all datasources have been closes, the empty datasource is used. This datasource cannot be closed (closing has no effect on it). -
COMMIT
A commit checks for an pending advance request and commites that request by moving the cursor of the currend datarow forward by one row.
