Hi Patricia, No, you can't fill in individual elements of an array using a REPEAT loop.If your variables with the start and end indices are defining constant-sized windows for the summing, then you should be able to achieve the same thing with the @SBX boxcar smoother - applied as one expression, not in any kind of loop.
Otherwise, there is always the inelegant but effective method of writing the results to a file at each iteration of your loop, then afterwards reading the result back into Ferret.

Dear ferreters, Ist there a possibility to do this: repeat/i=1:671 (let st=p_12111_st[i=`i`];\ let end=p_12111_end[i=`i`];\ let int_transp_s= var1211[i=`st`:`end`@SUM]) It should calculate the Sum and save it to the new grid of int_transp_s. Cheers, Patricia
