becoming one, like in a merger --therefore one of the two tickers is
no longer needed. The errors are caused by the numerical values for
H, Open, Low, Close being zero. I hope that the DB Cleanup command
will delete all the data in those tickers, and the tickers
themselves.... at least I'd like to hope so.
