Hi Ann,

I wondered if I would be getting a telling off from you! ;-)

Yup, thanks. I realised that I was talking via the wrong orifice, when I
updated the manual, I reworded it to be less "wrong" than what I posted
here. I must remember to engage brain before typing.

Ah! Now that's interesting. I need to update the manual again. This
implies that when this switch is used, some flag is set somewhere to
tell the system to leave no space? I assume that this is
"hdr_no_reserve" in the first page of the database.

Thanks for that, I'll do some more updating.
