tdef 365 linear 01Jan2003 1dy

with everything else as described below

Then use a couple loops and an array of month names to access each day

that
actually has data

mo=1
moname.1=Jan
moname.2=Feb
...

while (mo < 13)
da=1
while (da < 22)
'set time 'da%moname.mo'2003'
'd ndvi'
da=da+10
endwhile
mo=mo+1
endwhile

Something along these lines should work
