Well, actually you are! I might not have been precise enough when I asked the question but well... The example I gave was intentionally simple, the real situation involes moving block of data (of unknown size at compile time) from a given place (unknown at compile time) to another place - also unknown at compile time - although I know the new place has got a lower pointer value than the old one. -- For information on using the ACCESS Developer Forums, or to unsubscribe, please see http://www.access-company.com/developers/forums/
