Re: creating .nc file variables

 Hi Mary,

 Thanks a lot for your help!

 I did what you told me and it worked. It's accepting and creating the new
 file, but it's not writing the variables into it! Now it's giving the
 following message:

 ncvarput: ncid 12: Not a netCDF data type or _FillValue type mismatch
 fatal:NetCdf: An error occurred while attempting to write variable (psnm)
 to file (GBRAMS-6-hourly_1980-02_all-var-old_00.nc)
 fatal:Execute: Error occurred at or near line 143 in file read_brams.ncl

 PROGRAM LINES:
 142;**** Writing in "nc" files
 143 ncdf->psnm = pnmm
 144 ncdf->uvel = uu
 145 ncdf->vvel = vv
 146 ncdf->zgeo = ageo
 147 ncdf->temp = temp
 148 ncdf->umrl = RH

 I've tryed to change the way of calling the variables but it didn't work
 either!

 Thanks again!

 Rosa
 P.S.: The program file is attached!
