I am having fits making a transaction work. Code is:
... update data in form ...
BEGIN TRANSACTION
SELECT parent
lSuccess=TABLEUPDATE(2,.f.,ALIAS(),aSaveErrors)
...

I checked CURVAL() immediately before the tableupdate and immediately after. The table was UPDATED. I thought that BEGIN TRANSACTION created an additional set of buffers, TABLEUPDATE committed changes to those buffers, and END TRANSACTION committed those changes to disk. Here I see changes committed directly to disk - before END TRANSACTION is executed..

The table in question was opened with Optimistic Row Buffering.

Any ideas on what could be happening here? I have looked at this
until I am numb.

Thanks for any insight.
