It's a hidden extension very difficult to track down,
which makes .prg code prone to break when ported to
other xbase compilers (enough to see this example
on LetoDB). It can also break valid Clipper code in
some situations.

It's possible to overload $ operator to achieve the
same effect though in Harbour. It's implemented in
xhb.lib.
