I am sorry for any confusion. I should have stated the problem clearly.
I have data along an orbit, ie Time, X, Y, Z, and I wished to append 
data as I get it. I received a lot of RTFM replies, but fortunately a 
very comprehensive reply from Dr Carlie Coats at NCSC who somehow managed 
to understand what I needed. Many thanks to all who responded. My apologese
for wasting your time, and bandwidth.
