Templates

[Jean Pierre Arabonis]

Hi all
    I have several years worth of wavewatch 3 data in monthly files, I
would like to create a template ctl file to deal with specific months
over the years,  ie nww3.hs.199801.grb nww3.hs.199901.grb
nww3.hs.200001.grb nww3.hs.200101.grb  nww3.hs.200201.grb
 so I need a ctl file to describe them all, note the sequencing is
unimportant as I am looking at frequencies of occurrences.
my monthly ctl file looks like:

dset /data/Wamhist/working/nww3.hs.199801.grb
index /data/Wamhist/working/nww3.hs.199801.grb.idx
undef 9.999E+20
title /data/Wamhist/working/nww3.hs.199801.grb
*  produced by grib2ctl v0.9.12.5p32r
dtype grib 233
options yrev
ydef 157 linear -78.000000 1
xdef 288 linear 0.000000 1.250000
tdef 249 linear 00Z01jan1998 3hr
zdef 1 linear 1 1
vars 1
HTSGWsfc  0 100,1, 1  ** surface Sig height of wind waves and swell [m]
ENDVARS

I created a new ctl file called nww3.hs.all01.grb.ctl, and made the
following changes. ie
altered the dset line to read
    dset /data/Wamhist/working/nww3.hs.%y401.grb
the options line to
    options template  yrev
and the tdef line to
    tdef 1245 linear 00Z30jan1998 3hr

Now I can see the first file but all following ones display "entire grid
undefined"

    Anyone see where I am going wrong.

    Many Thanks
       Jean Pierre
