Hi, first, many thanks for the new release with all the effort involved. Next, great time for feature requests, hehe... I thought it would be nice if genseries() could be overloaded to accept an array of strings instead of a single string, and a list or matrix of corresponding dimensions, to produce several series in one go, avoiding the need for a loop. (The return type then would be a vector of IDs I guess, instead of a scalar.) cheers, sven
