One of the key features of Do-more is you can create a well-named block of bits called Alarm without the need for worrying about what your block of alarms bits in your C bit block is.
Allocate 96 of them to start, and if that isn't big enough later on, bump it by another 32 bits to 128, or 256 or whatever (it must be in blocks of 32 bits). No need to change your code, just use Alarm0, Alarm42, Alarm95, etc.
