>I see nothing weird here. Transaction and Buffering are different species. That's another story that when we use BEGIN TRAN then VFP itself will create something like a buffer internally (it's just a guess), but again it's internal code and not a programmer responsibility.
Ed,

It isn't event hat complex. When you start a transaction VFP gpooes into a mode that only secures locks needed to complete tasks, it does not actually do the tasks. It also maintains a list of the things to do. When you hit the end trans VFP acutally does the things. If you Rollbackl or the system crashes or the user shuts down before the trans is coimmitted, well the only thing to do is to release the locks because nothing has happened yet.
