It's a cheap method for the vendor, but as the above has discovered, may be very expensive to the user. The problem may be user error, system glitch, or dbms error. Regardless of which, the user is now faced with a big black box (a large extent of disk space known only as a huge "file" to the system) which is difficult to pene- trate with the usual system debugging tools and has to be overwritten in toto from backup. What did this user gain and was it really worth it, if (s)he did ? greg pavlov, fstrf, amherst, ny
