[netCDF #PRS-970596]: Help

Stephen,

> This did not seem to add the values to the level axis

Did it return an error?  Do you have a complete program that
we can use to reproduce the problem?  Sorry, but from the above
it's just not clear what you are trying to do and how it's
failing ...

> (I am using netCDF 3.6.x if this make a difference )

That shouldn't make any difference, it looks like you are only using
netCDF-3 functions.
