Usually you generate this state machine code from a higher level code.
Petri nets would be one (I have software like this on Linux), a quickly
hacked Prolog program another. The latter allows interactive simulation in
ways that I like.

Check if the compiler is reasonably efficient in compiling switches. If
not you will need to build a jump table instead. Also not by hand!
