Thanks, guys! This one works perfectly.
I was monkeying with similar logic but wasn't sure about syntax.

Here's a pretty straightforward approach:
combine  ys = ys
combine xs  = xs
combine (x:xs) (y:ys) | x <= y = x : combine xs (y:ys)
| otherwise = y : combine (x:xs) ys

Is there a simple way to combine two sequences that are in ascending order into a single sequence that's also in ascending order? An example would be the squares [1,4,9,16,25..] combined with the cubes [1,8,27,64,125..] to form [1,1,4,8,9,16,25,27..].
