>>Hello,

But I am at a loss how to name those methods, everything I can come up with ("SaveRecordNumber", "MoveBackToRecordNumber") do not sound anything intuitive. Anybody has a bright idea how to name those methods?

Thanks Tore, I like that. It's a little bit long, but better long and clear than short and cryptic.
