Use the one that's more readable. If you're testing for several values of the same expression, that would be Switch; it evaluates the expression only once. If you're testing for several mutually exclusive conditions, use Which. If you're testing one condition, use If. Bobby On Thu, 24 Feb 2011 05:20:42 -0600, Harvey P.
