[gradsusr] error in writing ascii data

[Jackie Yip]

Hi Mahesh,

I just moved your open file loopend to the end of the script. Give it a try.


Jackie

'reinit'
'clear'

year_st=1951
year_end=1953
yidx=year_st
while(yidx<=year_end)
'open /home/mahesh/data/ncep/ctl/precip_'yidx'.ctl'

tt=1
yrid=1951
fst=1
fend=3
fnum=fst
while(fnum<=fend)
 while(tt<=30)
     'set t 'tt
     'define arn=aave(precip.'fnum',lon=0,lon=40,lat=25,lat=55)'
    'd arn'
    lrn=subwrd(result,4)
    w=write(pnew.dat,lrn)
   tt=tt+1
 endwhile
 fnum=fnum+1
 yrid=yrid+1
'!mv pnew.dat pdata_'yrid'.dat'
endwhile

yidx=yidx+1
endwhile
