Ok, I think I understand what you are doing (I am still relatively new to Maple). distribute_sum() seems what I want. I did find out when playing with this somewhat more last night that expand() does pull out a factor from the sum quite nicely.

Also thanks for the suggestion to use the inert form, which I fact I also had discovered as being useful. Ultimately these will not be infinite sums but rather sums of data to be readin, but at this stage I don't want Maple to try doing anything with the sums (other than pulling out constants :-).

Thanks, I'll try your sugestions & get back.
