Synchronize @ or not ?

[n2ic]

I'm a Pascal/Lazarus newbie, so I'm sure this is obvious, but....

The code below gives me "Variable identifier expected" error on this line:

Synchronize(@ShowStatus);

But
Synchronize(ShowStatus);
without @ seems to work and build fine.

What's with that ?

Thanks !@

procedure TUdpThread.ShowStatus;
  var
     myStatusText : string;
  // this method is executed by the mainthread and can therefore access all GUI elements.
  begin
     myStatusText := fStatusText;
  end;

  procedure TUdpThread.Execute;
  var
    NewStatus : string;
  begin
    fStatusText := 'TMyThread Starting...';
    Synchronize(@ShowStatus);
    fStatusText := 'TMyThread Running...';

This was a Delphi project, converted to Lazarus, thus the {$MODE Delphi} .
