Do not use Switch.pm - it is a bad idea gone horribly wrong and will cause you hard to find bugs merely by its presence in your code.

As you didn't show the full code, I can't really make any better recommendation, but a set of if ... elsif ... isn't much worse to type than switch.

Update: Here are some local discussions of things to do instead of using switch: Switch.pm or possible alternatives, and here is discussion of some error as introduced by switch - I don't know if the code on quantums scratchpad is still there though.
