The sample code mentioned in the text can be found on the module repository. This coursework can be completed in Java, Kotlin, or Scala only. The aim of this assignment is to give you practice with subclasses, modifying existing code, and the use of reflection.

You will write an interpreter for a simple machine language — SML. The general form of a machine language instruction is

label instruction register-list

where:

• label: is the label for the line. Other instructions might “jump” to that label.
• instruction : Is the actual instruction. In SML, there are instructions for adding, multiplying and so on, for storing and retrieving integers, and for conditionally branching to other labels (like an if state- ment).
• register-list: is the list of registers that the instruction manipulates. Registers are simple, integer, storage areas in computer memory, much like vari- ables. In SML, there are 32 registers, numbered 0, 1, . . . , 31.
