>That was one of my questions in this thread, that Fabio and Gregory answered is not possible to achieve. My question was, is it possible to determine entry point and exit poin in REPLACE (or other commands) of this nature.

Yupp, but how about wrapping batch updates and setting a flag in such a case ?
One way to implement would be to send the command as parameter and macroexpand - the time lost for the one & should be more than made up by the caching of tableopening for a few hundred updates. Think outide the box...
