As Troy Horton wrote OnBar will solve all these problems. Greate.
Just some small points:

But 'drop' is ansi standard and a documented command so it *can't*
"imply" anything. It *is* a drop of the whole table.
It's of course still very easy to do something unintended with this or
other commands in dbaccess (and other tools).

Just be very carefull with the implications from transactions. You
might want to open the database in exclusive mode for this, or at
least lock the tables involved (if you use unload) so you can be sure
your data is consistent.
With OnBar there is hopefully functionallity for the same purpose.
