You just make a table of function pointers with the function names as the table entries. The syntax is a little strange the first time you do it. The implmentation by the compiler is excellent. Here are a couple of lines torn from my old code to show you an assignment method (as opposed to table):

void (*focus)(); // Holds the addr of the current func to exec.

focus = MyFunc; // Where somewhere I have a void MyFunc(void).

(*focus)(); // Executing the function in focus var.

Once you get that going, you can make a table of the MyFunc's. If it gives you the willy's, go with a switch statement.
