As anonymous arrays cannot be of any use as procedure parameters it
would be helpful to novices if BlackBox reported an error (or warning at
least). I checked the behaviour of Gardens Point Component Pascal with
the same code sample and it does in fact give a warning:
warning : The anonymous array type is incomptible with all values
