No. You access the data through %COMPANY_DB. That's the whole point of tie(). The object $db is used only if you need to call additional methods of MLDBM on it. You really don't even need to save $db, because you can always get it via: tied(%COMPANY_DB) perldoc -f tie perldoc -f tied perldoc perltie -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
