lats4d question

[Fan Fang]

Had the following error when trying to convert a grib2 file into hdf4 
format.  I am using lats4d in the grads-2.0.a7.oga.3 bundle.  The .ctl 
file has the lines around soilw40_100cm:

...
RH0C   0,4,0   0,1,1 ** 0C isotherm Relative Humidity [%]
SHTFLsfc   0,1,0   0,0,11,0 ** surface Sensible Heat Net Flux [W/m^2]
SOILW0_10cm  0,106,0,0.1   2,0,192 ** 0-0.1 m below ground Volumetric 
Soil Moisture Content [Fraction]
SOILW10_40cm  0,106,0.1,0.4   2,0,192 ** 0.1-0.4 m below ground 
Volumetric Soil Moisture Content [Fraction]
SOILW40_100cm  0,106,0.4,1   2,0,192 ** 0.4-1 m below ground Volumetric 
Soil Moisture Content [Fraction]
SOILW100_200cm  0,106,1,2   2,0,192 ** 1-2 m below ground Volumetric 
Soil Moisture Content [Fraction]
SPFH2m   0,103,2   0,1,0 ** 2 m above ground Specific Humidity [kg/kg]
...

Anyone has insight into this?  Thanks.
