That is good to hear.

These are warnings that something didn't go right, but from these two
lines we can't say what. Could you send a copy of the complete output
from "make test"? The output of the make may be useful if you still have
that around as well.

The readnet.for cannot read *any* netcdf file in the world. It can read any 
netcdf that has the same variables defined in it (variable attributes) as 
the file initially used by the compile of gennet.f. So, you may have a 
number of netCDF files containing the same variable (say pressure), but 
the data is from different measurements. The readnet.for generated by
gennet.f on one of these files will be able to read any of the other files.

If you then have a netcdf file with other variables in, you need to create
a new readnet.for by compiling gennet.f on this new file.

Towards the end of readnet.for is a section to allow you to do whatever
you wish with the variables in that fortran file.

You're welcome.

I have solved all of the problems and read the data from netCDF files
successfully. Thank you very much for your kind help. If there are any further
questions, I will contact you as soon as.
        Best regards!
