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="">
<br class="">
<br class="">
Marian<br class="">
