Gary:

Thanks for the bug report and
our heartiest thanks for including
a fix. Sorry that slipped thru.

FYI, the "rec" functions don't exist
in the new interface, only in the
backward compatibility interface.
The reasons for this are complicated.
The notion of a netcdf "record" is tied
more strongly to the current netcdf
file format. It is argueable whether or
not the notion has anything to do with
the abstract data model. As we evolve the
file format to allow multiple unlimited
dimensions, it won't make any sense.

So, as you migrate your code, think about
how else you might do what you need to do
using the new interface.

Since I'm cc'ing our support database with
this reply, I will include your message at
the end.

Thanks again.
