How
Thanks a lot for clarification.

if not, is there a clean and easy way to initialize the entire record
memory space to zeros e.g.
constructor TMyRecord.Create(TheValue : Integer);
begin
FillChar(self, sizeof(Self), 0);
Value := TheVal;
end;
Is there a Self variable for advanced record methods/constructors ?
By the way,
If in doubt, why not to use the old-school records and an
init-value procedure.
thanks,

does Advanced Record constructor automatically zero all the memory

No, it does not. Neither in Delphi nor in FPC.
