[netCDF #TLB-354751]: NetCDF IDL

Hi Patricia,

> I am trying to read netCDF files on IDL version 6.2 software.

The file netcdf.h, which may be installed in a directory for library include 
files,
has the error -31 associated with "system errors", such as inability to open a 
file
due to permissions problems. Usually the exact cause of the problem would be 
available
to the calling program (in this case IDL) as the value of a global variable 
named
"errno", which could then get translated into a meaningful error message by the
appropriate system call.

Sorry I can't be more helpful, but without the value of the global "errno" 
variable,
it's impossible to tell which of many errors listed in /usr/include/errno.h are
the cause of the problem.  The most likely error would be "no such file or 
directory",
indicating a bad file name or path name.
