It is legal to call this method with the index of a paragraph that contains no lines and with a linePosition argument of either 0 or -1. The IsInvalid, IsEnd, and IsFirst properties of the resulting iterator will all be True. Attempts to access any other property on this iterator will cause an exception to be thrown. This iterator may be supplied as an argument in a subsequent call to AddText.
