Dear Eduardo,<br>
<br>
Here is Example 3 from

I hope this helps,<br>

Another simple sample might be:
<p></p>
<pre> REAL X(100)
DO 10 I=1,100
X(I)=I
10 CONTINUE
OPEN (8,FILE='samp.dat',FORM='UNFORMATTED',ACCESS='DIRECT',
&RECL=100)
WRITE (8,REC=1) X
STOP
END
</pre>
<p>
The associated descriptor file:

Once created, you can use this data set to experiment with GrADS
data functions, such as:
</p>
<p></p>
<ul>
<code><a href="http://grads.iges.org/grads/gadoc/gradcomddisplay.html">display</a>
<a href="http://grads.iges.org/grads/gadoc/gradfuncsin.html"> sin</a>(x/50)
</code>
</ul>

<br>
<br>
I am trying to write two different time series into a .grd file so I
can
<br>
view them and for example do a scatter plot of the two time series in
Grads
<br>
<br>
within the Fortran program, I do:
<br>
<br>
open(14,file='scatter.grd',form='unformatted',access='direct',recl=4*109)
<br>
write(14,rec=1)(IE(itime),itime=1,109)
<br>
write(14,rec=2)(data1(3,it),it=392,500)
<br>
close(14)
<br>
<br>
but in Grads this just opens two time series, length 54 that take
<br>
alternating values from one of my initial time vectors- in this case,
<br>
IE(itime)
<br>
<br>
My ctl file is:
<br>
DSET scatter.grd
<br>
TITLE HGT
<br>
UNDEF -99
<br>
TDEF 109 LINEAR 1aug90 1mo
<br>
XDEF 1 LINEAR 1 1
<br>
YDEF 1 LINEAR 1 1
<br>
ZDEF 1 LINEAR 1 1
<br>
<br>
VARS 2
<br>
f1 1 99 HT data
<br>
f2 1 99 HT data
<br>
ENDVARS
<br>
<br>
Any help is very much appreciated
<br>
<br>
