<p>Hello Jennifer,</p>
<p>thank you for your reply. I have already got helped. I am using
older version under Windows (btw. where can I download the latest
pack?) , so for now I do it like this:</p>
<p>'set prnopts %.0f 1 0'<br>
'd TCDCclm'<br>
cloudbfr = result<br>
oblc = sublin(cloudbfr,3)</p>
<p><br>
</p>
<p>if (oblc<10)<br>
obla='J'<br>
endif</p>
<p>............................................................<br>
</p>
<p><br>
</p>
<p>Kindest regards,</p>
<p><br>
</p>
<p>Marian<br>

The ‘if’ function <b class=""><i class="">in the scripting
language</i></b> doesn’t work for evaluating the data in a
defined variable in GrADS; it is only for evaluating script
variables. As of version 2.1.1.b0, there is an if() function in
GrADS and logical operators in the expression syntax for doing
this type of calculation. If you are using an older version of
GrADS, then the maskout() and const() functions can be used to
achieve similar results.

Dear GrADS users,<br class="">
<br class="">
<br class="">
I have been on this half a day, but still no success.<br
class="">
<br class="">
Part of my script:<br class="">
<br class="">
'define oblc = TCDCclm'<br class="">
<br class="">
if (oblc<10)<br class="">
obla='J'<br class="">
endif<br class="">
if (oblc>=10 & TCDCclm<30)<br class="">
obla='SJ'<br class="">
endif<br class="">
if (oblc>=30 & TCDCclm<60)<br class="">
obla='P'<br class="">
endif<br class="">
if (oblc>=60 & TCDCclm<90)<br class="">
obla='O'<br class="">
endif<br class="">
if (oblc>=90)<br class="">
obla='Z'<br class="">
endif<br class="">
<br class="">
I want to get obla string based on the total cloud cover,
but somehow the conditions dont work. I always get the last
obla='Z' eventhough the TCDCclm is 34%<br class="">
<br class="">
Could you please guide me on the right track?<br class="">
<br class="">
<br class="">
Thank you in advance for your replies.<br class="">
