And a switch is a lot neater for dealing with these sorts of things. I
tend never to use if...elseif's at all, and use switches. Like Rob said,
you can fall into further cases below, and it's very simple to add more
at a later date. There is one place where an if...elseif would work and
a switch could not, and that is where you were performing lots of
different logic tests on different variables. Aside from that, I think
any speed benefit one would have over the other would be marginal.
