You will probably want to approach this from a different way. If your values are monthly averages, try something like (assuming a start year of 2002 and an end year of 2010):
<div><br>
</div>
<div><br>
'open temp.ctl' <br>
'set x 1 144'<br>
'set y 1 73’</div>
<div><br>
</div>
<div>year=2002</div>
<div>while (year<=2010)<br>
'd aave(ave(temp-273.15,time=JAN'year',time=DEC'year'),g)'<br>
secondline=sublin(result,2)<br>
globalave=subwrd(secondline,4)<br>
say globalave<br>
year=year+1<br>
endwhile</div>

<div>I think that expression will give you the average January temperature. If you want a monthly time series of temperature averaged over a specified (prior, following, or centered somewhere) 12-month window, you could use something like<br>
</div>
'd ave(temp-273.15,t-0,t+12)'<br>
</div>
although you may want to verify if that is valid first.<br>
<br>
</div>
If you are looking strictly for a JAN-DEC average each year, I'd look into using tmave().<br>
