Sergey, Many thanks to you and your colleague for persisting and for providing that small program that demonstrates the bug. It looks like I can duplicate the problem here, even with our latest release, so this will probably result in a bug fix. I'll send more information in a subsequent email, but I may not get time to figure out what's happening and provide a fix until tomorrow. --Russ Russ Rew UCAR Unidata Program address@hidden http://www.unidata.ucar.edu Ticket Details =================== Ticket ID: MOB-465267 Department: Support netCDF Priority: High Status: Closed
