Given two lists A={a1,a2,a3,...} B={b1,b2,b3...} I want to produce the list C={ {a1,b1}, {a2,b2}, {a3,b3}...} } as efficiently as possible. Better yet, generalize to do this with N lists all of same length. Obviously it can be done directly with Table, but is there a more elegant, implicit way to write it that doesn't involve passing a function to Table and using an explicit index? Is there a general functional primitive for this that I simply haven't found? Seems like something so common, there ought to be a built-in function for it. Thanks, Roger
