This is just a hunch, but I wonder if you actually mean this:-
disp_digits="0123";
This effectively assigns ASCII "0" to the first element, "1" to the second and
so on, with a null (ASCII 0) in disp_digits[4]. As you have written the code,
if the array is treated elsewhere as a string, starting with a true zero will
make it appear like an empty string.
Just a thought - it's such a common mistake that I thought it might be worth a
mention.
