The transition from ZOZ to WIZ - page 1 A ZOZ instruction, "A -> B", consists of two serial numbers, eg: 58574900948484 -> 2930484518273950 Serial numbers, being unique across the galaxy, require many digits. Physicists generally agree there might be 10^79 particles in the universe. That puts an upper limit for serial numbers at 79 digits (lol). The ZOZ uses WIZes as resources to get instructions executed. But a WIZ processor cannot execute ZOZ instructions! WIZes have a 16-bit instruction word, with two 8-bit register addresses and cannot handle long ZOZ serial numbers. For suppose, for example, if device 58574900948484 sits behind register 115 in some particular WIZ, and device 2930484518273950 sits behind register 28 in that same WIZ. While this instruction: 58574900948484 -> 2930484518273950 cannot be executed per se, this one can: 115 -> 28 In the context of this one particular WIZ, these are the exact same instruction, merely using different numbers to reference the same objects.
