Re Mathematica 5.2.0.0. Why doesn't: (a b) /. x_Times -> List @@ x return {a,b}? My (flawed) reasoning is that a b has form Times[a,b], and so x matches to Times[a,b]. List@@x replaces Times with List to yield List[a,b], or {a,b}...or so it would seem. The explanation is somehow linked to the fact that: (a b) /. x_Times :> List @@ x returns {a,b}, but I don't see why this works but not the above. Although List@@(a,b) returns {a,b}, I want to use the above ReplaceAll function (this example here is taken from a larger problem). Thankx. Bruce
