Then make a switch of switches, but yes, that's when I would say, screw all
that stuff, make a jump table with conditionally
evaluated indexes, and call it a day.
For more info on this, see how lex and yacc generate their tables.
Take care,

That's assuming you don't have complex conditions you're checking for;
sometimes, if/else if is the only way to go. When code becomes
long/slightly unreadable, refactoring usually is a good idea.
