[ncl-talk] using ind to subset a variable in addfiles

[Adam Phillips]

Hi Adam,
Just a guess, but what happens if you do this:
invarT = inptr[:]->PRECC
invar = invarT(indt,indcol)
I have a memory that every once in a while subsetting a read-in variable
from addfiles can be more time consuming than reading in the variable and
subsetting it afterwards.
Hope that helps!
Adam
