===Uncompressing Packed Bytes into ASCII Zeroes and Ones===
Code is optimized to use what I call a "revolving bit mask" since there is no way to iterate through <code>BIT</code> commands without self-modifying code which is even more difficult to read in my opinion. Using <code>BIT</code> tests without self-modifying code would require the loop to be unrolled.
