I'm reading the Dragon book at the moment and recently came across
switch statements in intermediate code generation. There are given two
alternatives, one is a series of if statements, the other involves
building a hash table. Now is this really commonly done or is it often
simply the if approach because it's simpler?

cases are all in sequence or close to it. -John]
