I am confused. If you can read these data files into
anonymous structures, and you make an ARRAY of
these anonymous structures, why can't you just
loops through the data files, reading each file,
and then storing the data in the appropriate location
in your array of structures? In the end, you will
have (or can easily create) what you want.

Well, if only the last station values get stored, then
I would think the ONLY solution would be to index the
station values. But I can't really tell from your description
what you think that means.

I think you are trying to make it too hard. If you already
have something that works, just do that thing for all your
data files. In the end, you can treat your array of structures
in the way you apparently want to treat your data.
Cheers,
David

Yes, you were right :) It was a mistake with the declaration, being
the lazy sort, I didn't wanna go through the many lines of code (tho
they are my creation!) :p
Thanks for your time. I appreciate it.
