{ a | a in lower..upper: a mod stepsize ==0 }

Hi

could the following help you?

{ lower +stepsize *k | k in 0..(upper-lower) div stepsize };

Thanks for that suggestion. I went ahead with my earlier version, and there does not appear to be a speed obstacle. Your version is clever and would appear to require less processing.
