Hi All,
  How do i check whether a range is empty. eg. 
(!PFResutl.toRange).empty. I tired the below, but it is no 
printing Empty if the range is empty it just prints blank line.

if (!(!PFResutl.toRange).empty) { writeln("Empty"); }

I thought every range at the lowest level has an `empty` 
property. So, in this case, it would be:

if (PFResutl.toRange.empty)
{
    writeln("Empty");
}
