Hi Tracey,
<div><br>
</div>
<div>That’s getting into the difference in a grads script variable and variables used on command line and such. Anything you put in quotes would be something you could type into a Grads command line session.</div>
<div><br>
</div>
<div>If you modify your script like:</div>
<div><br>
</div>
<div><span class="">lonmine = 360 - lonmin<br></span><span class="">
lonmaxe = 360 - lonmax<br>
say lonmine<br>
say lonmaxe</span></div>
<div><br>
</div>
<div>It should work.</div><span class="HOEnZb"><font color="#888888">

Thanks for your response! I'm still a little bit confused though. I am passing into the script a grid, for example: </div>

<div dir="ltr">Hi Tracey --
<div><br>
</div>
<div>There's a difference between a script variable and what I believe is called an
<i>intrinsic</i> variable, in GrADS. With script variables, you would indeed use "define". But for intrinsic variables (and this from my experience needs to be in a script), I believe you'd have to pull the values from a string of display-ed data.
That is:</div>
<div><br>
</div>
<div>"d lon"</div>
<div>lonw = subwrd(result,<leftmost character position>, <rightmost character position>)</div>
<div><br>
</div>
<div>where leftmost and rightmost refer to the left and right position in the line that includes the variable lonw.</div>
<div>If there are multiple lines in the display, you'll have to first choose the line that contains the longitude. If it were the 2nd line, you'd have the command
<br>
</div>
<div><br>
</div>
<div>lonline=sublin(result, 2)</div>
<div>then do subwrd(lonline, <leftmost>,<rightmost>) as above.</div>
<div><br>
</div>
<div>Finally, you'd define your lone = 360 - lonw ("define lone = 360 - lonw").
<br>
</div>
<div><br>
</div>
<div>I'm doing this from memory ... it's been awhile since I wrote a script. I'll check it out once I'm where I can write a test script and see if this works.</div>
