I've run into this before and didn't find a convenient way in Compute to do this consistently. Because some functions don't like NaNs or NaNQs, I've usually had to do some filtering prior to Import or eliminating the cause of the NaNs in the files. If there is a way to do it in Compute, I would find it useful.

Is there a Compute function or something I should be using to do this? I know NaNs compare strangely, which helps explain why Include( -10000 <= x <= 10000 ) didn't work, but Include( x <= -10000, exclude ) did.
