I've
seen your various posts and I keep meaning to ask you. I'm in
Auckland. More explicitly, I'm in Albany. But I will be shifting to
South Head (near Helensville) in October, as soon as my new house is
finished.

I
always learn something from each of your posts and I'm sure that others
appreciate the assistance you offer.

Thanks
from all of us.

[EquisMetaStock Group] Barssince in
explorationRonI'm glad I got something right
first time. It hasn't been a good week inthat regard and I've looked a bit
of an idiot at times.Any function that uses "Nth" event can also
benefit from a simple piece ofinitialisation code. It works better than
IsDefined() or Is Undefined(), butthat's not really any sort of
recommendation I guess.Roy----- Original Message -----
