I am working with some IPv6 addresses that are 128 bits long. The input to the program is an ip name or address and the number of high bits that I need to use for a compare against another ip address.
So, I want to create run time routine to build the a 16 byte 'and' bit field based on the input number of bits. (I will then 'and' both addresses and then use a simple CLC.) Although a table built at compile time might be a reasonable solution, I thought this would be a good time to learn a new trick if someone has one they can share. -- Tony Thigpen
