Delphi and Kylix has done the exact same thing for years. In this case FPC is just Delphi compatible. As for the extra check causing a hit in performance - I can't say I have ever noticed it in our projects where we often create and destroy 80,000+ objects. It's a safety net, and a handy one. Maybe you can put together a speed test app and post your results. One test calls .Free, the other test calls .Destroy -- Regards, - Graeme - _______________________________________________ fpGUI - a cross-platform Free Pascal GUI toolkit http://opensoft.homeip.net/fpgui/ _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
