True, but A and B are listed as vectors already, so that may lead to some unintended consequences.

To Maria, IDL only lets you return one variable with the RETURN statement. To pass more data out of your function, you either need to concatenate arrays like Wayne showed, or use named variables like Matthew Argall showed. Neither is very intuitive for a non-programmer.
