I remember as a newbie to the list, I'd asked this very question a couple of 
years ago. A few members kindly replied, and since then I've gone on to create 
many projects implementing their advice.

Try:

void (*do_func[])(void) PROGMEM=
    { func1, func2, func3, func4, func6 };

int main(void)
    {
       void (*func)(void);

        while(1)
           {
                        .......
                (fun= pgm_read_word(&do_func[func_no]))(); //func_no is the 
element no..
                .......
           }
        return 0;
     }

Bye,
