[Manish Singh]

Hi all ,
         As i have tried to make ctl file for monthly output of mom3
model ,which are in the form of .nc files .When i have tried it on
windowsxp then i have got an error of type :

dset  c:/time_mean.00%y4.%m2.01.nc
dtype  netcdf
options  byteswapped little endian template
undef -1.e+34
xdef 240 linear 0.75 1.5
ydef 134 levels -74.25 -72.75 ---------------------------------
zdef 25 levels 7.5 22.5 37.5 52.5 -----------------

tdef 5  linear 01jan1952 1mo
vars 2
temp        25  t,z,y,x  Potential Temperature (deg C)
salinity    25  t,z,y,x  Salinity (ppm-0.035)
endvars


open c:\ocean_4D.ctl
Scanning descriptor file : C:\ocean_4D.ctl
open error :Data file type invalid
 -->The invalid description file record is :

I have also tried it for itanium ,but in that one  i again got same
problem .

A lot of thanks in advance.
