Many thanks for this suggestion. I didn't know that memcpy_P existed but I do
now. And I think initialising arrays will work for me as well since the names
are all 3 or 4 characters in length so the program memory wasted by declaring:
char name[5];
..will be more than compensated for by not storing 16-bit pointers to the
strings in program memory:
flash: 88 bytes
RAM: 0 bytes
