Does that mean that Free itself reclaims the memory used by the object's fields and properties but does not release the memory used by the TObject or pointer itself, where as setting it to nil or executing Destroy does, or does Destroy do something different? All memory is released including TObject but the variable pointing to the TObject (fe: SCStrings) isn't set to nil. It still points to where the TObject was. Warning: setting a TObject variable to nil does not free the object unless it is reference counted! Strings and COM style interfaces are reference counted. Pascal is not VB. Ludo
