HI
I have 500 data files.Using these data file I want to extract some parameters with in 10 to 14 pm from global attributes of the data files with the .jnl script as bellow:
def symb start=1
def symb end=500
def axis/t0=15-May-2009/t=1:500:1/unit=hours tax
repeat/range=($start):($end)/name=yy (;\
use may`yy`.nc;\
let lat1=..botlat;\
let lat2=..edmaxlat;\
let lon1=..botlon;\
let lon2=..edmaxlon;\
let alt1=..edmaxalt;\
let month=..month;\
let edmax=..edmax;\
let lct=..botlct;\
let day=..day;\
if ` lct1 ge 10 and lct1 le 14` then ;\
let lat11=lat1+0*t[gt=tax];\
let lat12=lat2+0*t[gt=tax];\
let lon11=lon1+0*t[gt=tax];\
let lon12=lon2+0*t[gt=tax];\
let alt=alt1+0*t[gt=tax];\
let month1=month+0*t[gt=tax];\
let edmax1=edmax+0*t[gt=tax];\
let lct1=lct+0*t[gt=tax];\
let day1=day+0*t[gt=tax];\
let ed135=if elec_dens[x=70:700:0.001] lt 0 then 0 else elec_dens[x=70:700:0.001]*10^6;\
let ed_tec1=ed135[x=70:200@din]+0*t[gt=tax];\
let ed_tec2=ed135[x=200:350@din]+0*t[gt=tax];\
list/file=
mday9_ma22.nc/format=cdf/clob/l=`yy`/llimits=1:500 lat11,lat12,lon11,lon12,alt,month1,day1,lct1,edmax1,ed_tec1,ed_tec2;\
else ;\
list/app/file=
mday9_ma22.nc/format=cdf/clob/l=`yy` lat11,lat12,lon11,lon12,alt,month1,day1,lct1,edmax1,ed_tec1,ed_tec2;\
endif ;\
can da/all ;\
)

The result is as follwes;
