One possibility is to try:<br>
<br>
a.count=subwrd(result,3)<br>
<br>
this will generate a subscripted array "a" with ten values, for your
example. Here is some documentation from<br>
<a class="moz-txt-link-freetext" href="http://grads.iges.org/grads/gadoc/script.html#variables">http://grads.iges.org/grads/gadoc/script.html#variables</a><br>
<br>
------------------------------------------------------------------------------------------------------------------------------------------------<br>
<p><i><b>Compound string variables</b></i>
</p>
<p>Compound variables are used to construct arrays in scripts. A
compound
variable has a variable name with segments separated by periods. For
example:
</p>
<p></p>
<ul>
<code>varname.i.j</code>
</ul>
<p>
In this case, when the variable contents are accessed,
<code>i</code> and <code>j</code> will be looked up to see if they are
also variables (non-compound). If they are, the <code>i</code> and
<code>j</code> will be replaced by the string values of <code>i</code>
and <code>j</code>. For example:
</p>
<p></p>
<ul>
<code>i = 10 <br>
j = 3 <br>
varname.i.j = 343</code>
</ul>
<p>
In the above example, the assignment is equivalent to:
</p>
<p></p>
<ul>
<code>varname.10.3 = 343</code>
</ul>
<p>
Note that the string values of <code>i</code> and <code>j</code> may
be anything, but the variable name specification in the script must
follow the rules for variable names: letters or numbers, with a
leading letter. The variable name after substitution may be any
string:
</p>
<p></p>
<ul>
<code>i = 'a#$xx' <br>
varname.i = 343</code>
</ul>
<p>
The above is valid. However, we cannot refer to this variable
name directly:
</p>
<p></p>
<ul>
<code>varname.a#$xx = 343</code>
</ul>
<p>
would be invalid.
</p>
<p>Variable names may <i>not</i> be longer than 16 characters, either
before or after substitution.
</p>
<p>Note that the GrADS scripting language is not particularly
efficient in handling large numbers of variables. Thus compound
variables should not be used to create large arrays:
</p>
<p></p>
<ul>
<code>i = 1 <br>
while (i < 10000) <br>
var.i = i <br>
i = i + 1 <br>
endwhile
</code>
</ul>
<p>
The above loop will create 10000 distinct variable names. Such
a large number of variables in the variable chain will slow the
script down a lot. </p>

I hope this helps,<br>
