Triggers and UNDO, LEAVE, NEXT, RETRY, RETURN

When defining a trigger to perform the following actions, the action
is performed on the trigger itself since it is the innermost block
of code:

UNDO
RETRY
LEAVE
RETURN
NEXT

Example:

DEFINE BUTTON btn-a LABEL "Button A".
ON SELECTION OF btn-a UNDO,RETRY.
REPEAT:
ENABLE btn-a.
WAIT-FOR SELECTION OF btn-a.
DISABLE btn-a.
END.

Selecting BTN-A will cause the trigger to be undone and re-tried,
not the repeat loop.
