[Support #JPR-616713]: Large NetCDF files and IDL 7.1 ????

Sorry, but we don't know if there is such a patch or if so, how to get it.
I suggest asking IDL support if such a patch exists.

You may be thinking that netCDF-4 support (supposed to be in IDL version 7.2) 
is needed to create 5-10GB netCDF files, but it may be possible to create 
such large netCDF files using netCDF-3 in the current IDL.  For details, see 
the answers to these FAQs:

  How can I write variables larger than 4 GiB?

and 

  Was it possible to create netCDF files larger than 2 GiBytes before version 
3.6?
