Ignorance, I suppose. I note that NCDF_DATA is very old.
I keep it around because it has the incredibly handy
ability to browse netCDF and HDF files. For most of
my real netCDF work, I use my NCDF_FILE object, which
works exactly as yours does. (I had learned something
in the intervening years, thank goodness!)

I just tried creating and destroying a NCDF_FILE
object 16500 times, and had no trouble doing so
using IDL 8.1 on Windows.

What version of IDL are you using? And, on what OS?

Cheers,

David
