Enicho, I fixed the bug in ncgen revealed by your example, so now instead of ncgen -f 4000073_prof.cdl > 4000073_prof.f Segmentation Fault(coredump) I get ncgen -f 4000073_prof.cdl > 4000073_prof.f ncgen: 4000073_prof.cdl line 609: FORTRAN statement to assign values to PROJECT_NAME too long! This fix will appear in the next release. --Russ Russ Rew UCAR Unidata Program address@hidden http://www.unidata.ucar.edu Ticket Details =================== Ticket ID: YCK-274847 Department: Support netCDF Priority: Critical Status: Closed
