We have come a long way and have covered almost every aspect of Assembly programming basics. In fact, we should be able to implement any algorithm in Assembly language by this time; however, there are a few important things left we have not touched yet, but they are nonetheless important to know.

Despite the fact that writing relatively large parts of a product (not to say writing a complete product) in Assembly language may not be the best idea when it comes to timelines, it may still be a very interesting and challenging task (educational as well). Sometimes it is more convenient to implement certain parts of an algorithm in Assembly, rather than using a high-level language. Remember the tiny virtual machine we used for XOR encryption of data? For the sake of an example, we will implement a simple encryption...
