[ncl-talk] sub: Second do loop

[Dennis Shea]

'dale zuri' ...

Please understand 'do loop's. The 'tt'.ncl' script is a nuisance to look
at. No indentation and many commented out lines. Please send  clean,
structured code. Out time is valuable too!

===
You must understand do loops.

At the top you have:

do i=0,st
nums1=k1(i:i+c,0);;;;;;;observtion

then within the same 'do lop' you have

[SNIP]
OrigMod=new(st+1,float,yu at _FillValue)
do i=0,st                                 :<=================
OrigMod(i)=arraycdfinverse
end do
end do

The 2nd do attempts to redefine th 'i' ... this is not allowed!!
