This means that when a method creates new object $no:=New object fact that $no is local variable matters to the extend that, when methods ends, $no gets out of scope and the refcount of the object is decreased by 1. If no other variable refers to the object, it is destroyed. However, there may be other variables that refer to that object, if you do something like procesVar:=$no or SomeMethod($no) In this case, object exist till last variable stopp to reference it. -- Peter Bozek ********************************************************************** 4D Internet Users Group (4D iNUG) Archive: http://lists.4d.com/archives.html Options: https://lists.4d.com/mailman/options/4d_tech Unsub: mailto:4d_tech-unsubscr...@lists.4d.com **********************************************************************
