>WHY DOES THE RI CODE GET LOST ON A DELETE TAG ALL??? ah, that's simple :) the RI , Primary key etc. are stored in the dbc and are based on the index info if you delete the primary index with a DELETE TAG ALL how can the dbc maintain it as a primary key etc. >(By the way, is it documented that it does so? (I have not come across it >if it is)) I don't know if it is documented Arnon
