This is now the second post on this topic here. Did you read my answer on ProgressTalk?

What it does will depend on what is defined as a transaction. Use COMPILE LIST to see where the transactions are. Use the transaction keyword to scope the transaction to the desired block. You can either make each update independent or make all of the updates a single transaction.
