It should be possible to build the netCDF package using the the IRIX
Fortran compile with the "-r8" option (I just did this). After that, it
should be possible to use the ...VAR_REAL routines to access NF_FLOAT
data.
Note that the Fortran-90 interface of the the netCDF library cannot be
built if the "-r8" option is used.
Please keep me apprised.
