For example, ZOZ object #1357 might be a thermometer, and ZOZ object #2468 might be a ceiling fan. If the thermometer outputs a number from 0 to 100, representing its temperature in degrees Celsius, and if the fan inputs a number to set its speed in revolutions per minute (RPM), then the single instruction:

    1357 => 2468

will cause the ZOZ to get the temperature from thermometer object #1357 and transport it to fan object #2468. If the thermometer outputs 22 degrees, the fan will spin at 22 rpm.

Serial numbers 1357 and 2468, a thermometer and a fan, could be in the same room. But they could just as well be the serial numbers of a thermometer on Mars and a fan on Venus. To the ZOZ, they are just serial numbers, and wherever they are, it will find them and transport a datum between them.

ZOZ objects can do arithmetic too. Imagine a "doubler" object, serial #22344. Whenever read, it will output double the number last written to it. For example, we could do the following pair of instructions:

    1357 => 22344       // this routes the thermometer's output to the doubler's input
    22344 => 2468       // this routes the doubler's output to the fan's input

Now, if the temperature were 22 degrees, the fan will spin at 44 rpm.
