Exactly! A 15-digit >-Binary-< number would be 1010101010101010 (well, that's 16, but who's counting).

The original post said, " I thought 15 was the number of digits, but I guess it is the number of bits. So, I
should have had a 2-byte binary number..."

Last time I checked a 2-byte binary number was 16 bits; 16 ones/zeros, or 15 + a sign bit.

255 * 255 = 65025 combinations
