It was nothing, really.

I have been away (slaving in the olive grove) since midday Friday NZ
time, so I have not had the pleasure of participating in this thread
since then.

OK, but you posted information about the *difference* between the data
formats before and after 1 Jan 1995, so I naturally assumed this was
relevant in some way.

Ah. So you have written IDL code which should read the data, but it doesn't.

Do you actually know that your routine will read the data as described
in the User's Guide? It might take some effort to verify this, but it
would be nice to be able to start from some code that successfully reads
*something*.

I suggest you get some coffee (or other legal drug of choice), the
User's Guide and whatever "help" info you can, open up your code in the
IDL editor, add some breakpoints, and work your way through the data,
critically examining every number produced by every READ statement.

Look on the bright side: when you've finished you can post your code
here and achieve instant fame and fortune. ... On second thoughts,
forget about the fortune.
