Read DOS 16 Bit Edition

 

Here are some examples made by me:

 

You must understand Low Level Programing language, Assembly instructions. Here is a Simple Example:

mov ax, ds:[10h]
mul ds:[12h]
mov ds:[10h], ax
mov ax, ds:[12h]
mul ds:[12h]
add ds:[10h], ax

And the High Level Programing translation is:

int16 a = ?; //ds:[10h]
int16 b = ?; //ds:[12h]
a = a * b;
a = a + b * b

Or something like this:

push ebp
mov ebp, esp
...
mov eax, something
mov esp, ebp
pop ebp
retn

 

Translation:

type myFunc(){
...
return something;
}

And more, And another book that i suggest:
