[netCDF #EOB-623455]: nf90 number of Global Attributes

Hello,

My apologies for the delayed response.  I will try to discover the answer for 
you, but unfortunately Unidata does not currently have any Fortran expertise 
in-house.  As a result, Fortran questions take an extended amount of time to 
resolve.  Are you able to provide the netCDF file you are working with? The 
first step will be to see what happens using the C library interface.  Since 
the Fortran interface is essentially a hook into the C library, we can begin 
there and work backwards.

Thank you,

-Ward
