 ```
     run Calculator with Opcode and Arg1 and Arg2

 Next we have the value handler object. This contains the compiler function `compile(compiler)` and the runtime function `get(program, value)`. Between them they provide the means to access any of the properties of the box variable, plus the volume, which is computed on the fly at runtime.
