While all-pipes solutions are usually elegant and always inherently cool, either Bob's or the Piper's could be a challenge to build dynamically. I'd probably use one or the other - or something similar - for a fixed case, but I think Shimon's search for a generalized solution would be more easily addressed by a Rexx stage and wouldn't suffer that much of a performance penalty.
