[gradsusr] OLR daily anomaly for DJF

[Thomas Robinson]

I use while to do loops in grads.
http://www.iges.org/grads/gadoc/script.html#while

Try this:

'define OLRave=ave(olr,time=21jan2001,time=21Jan2011,365)'
count_time=2001
while (count_time <=2011)
'c'
'set time 21Jan' count_time
'define anom=olr-OLRave'
'd anom'
'printim OLRanom' count_time '.jpg'
count_time=count_time+1
endwhile

I added a printim so you can get quick output to look at also, otherwise
your images will be made and then they will be deleted by 'c'.

I hope this helps

-Tom
