Using Murray's approach I end up with (for example): Clear[a, b, c] rules = Thread[{a, b, c} -> {0.1, 0.1, 0.1}] Table[rules /. ((b -> _) -> (b -> i/10.)), {i, 0, 10}] Using Peter's approach I end up with (for example): Clear[a, b, c] rules = Thread[{a, b, c} -> {0.1, 0.1, 0.1}] Table[(rules /. HoldPattern[b -> _] :> b -> i/10.), {i, 0, 10}] Both appear to meet my needs. I'm not sure what the real difference between the two is. Thanks, Alan Thanks! Alan
