\=============================/

C++ version. Cus I want this shit to be cross-platform
and native.

The purpose is to make a retro computer simulation of
those 80s micro-computers. It will work with BASIC and
will have some basic commands like PRINT, DIM, INPUT, etc.

This is a very simple program not designed to make you a
developer.
