You go and check it, and you'll know. The reviews of this book are mixed. The good things say it makes assembly language look like a high-level language and can develop large programs with the help of the HLA they made. The bad things say if writing assembly language looks like writing C, it's better to just learn C directly. I think both have their reasons. Nonsense, it's like not saying anything. But I think the key issue is not that this method in the book is bad. To put it simply, his plan is just a packaging of assembly language. In a sense, instead of packaging, it's better to just learn a high-level language directly, especially when his set of plans hasn't become an authoritative standard. So I suggest everyone not to waste time on this book.
