Dear Grads users

I have a problem generating a ctl file to read 11 years of data downloaded
from ECWMF. I can read individually with sdfopen, however, when I tried to
create a ctl file I think I have problems declaring the variable. My
ctl file looks like this

DSET ^q-%y4.nc
UNDEF -999.99
OPTIONS little_endian yrev zrev template
DTYPE netcdf
XDEF 111 linear 275.000000 0.500000
YDEF 135 linear -55.000000 0.500000
TDEF 16072 linear 00:00Z01jan1999 6hr
zdef 11 levels 1000.000000 925.000000 850.000000 700.000000 500.000000
300.000000 250.000000 200.000000 100.000000 20.000000 10.000000
vars 1
q 11 99 Specific humidity [kg kg**-1]
endvars

I read that I can not use 99 for my variable definition, however I'm
clueless about what to put in that line

The ncdump -h from an individual netcdf file looks like this
netcdf q-1999 {
dimensions:
longitude = 111 ;
latitude = 135 ;
level = 11 ;
time = UNLIMITED ; // (1460 currently)
variables:
float longitude(longitude) ;
longitude:units = "degrees_east" ;
longitude:long_name = "longitude" ;
float latitude(latitude) ;
latitude:units = "degrees_north" ;
latitude:long_name = "latitude" ;
int level(level) ;
level:units = "millibars" ;
level:long_name = "pressure_level" ;
int time(time) ;
time:units = "hours since 1900-01-01 00:00:0.0" ;
time:long_name = "time" ;
time:calendar = "gregorian" ;
short q(time, level, latitude, longitude) ;
q:scale_factor = 3.60802682733904e-07 ;
q:add_offset = 0.0118165291556829 ;
q:_FillValue = -32767s ;
q:missing_value = -32767s ;
q:units = "kg kg**-1" ;
q:long_name = "Specific humidity" ;
q:standard_name = "specific_humidity" ;

// global attributes:
:Conventions = "CF-1.0" ;
:history = "2015-11-03 16:49:08 GMT by grib_to_netcdf-1.13.1:
grib_to_netcdf
/data/data04/scratch/netcdf-atls20-a562cefde8a29a7288fa0b8b7f9413f7-AHRBQo.target

/data/data04/scratch/netcdf-atls20-a562cefde8a29a7288fa0b8b7f9413f7-ZNlmj2.nc
-utime" ;
}

Best regards
Luis
