Am I Writing Assembly Or NASM?
- by cam
I'm fed up with this. I've been trying to just get a grip on assembly for awhile, but I feel like I'm coding towards my compiler rather than a language.
I've been using this tutorial, and so far it's giving me hell. I'm using NASM, which may be the problem, but I figured it was the most popular one. I'm simply trying to learn the most general form of assembly, so I decided to learn x86. I keep running into stupid errors, like not being able to increment a variable. Here's the latest one: not being able to use div.
mov bx, 0;
mov cx, 0;
jmp start;
start:
inc cx;
mov ax, cx;
div 3; <-- invalid combination of opcode and operand
cmp ah,0;
jz totalvalue;
mov ax, cx;
div 5; <-- invalid combination of opcode and operand
cmp ah, 0;
jz totalvalue;
cmp cx, 1000;
jz end;
totalvalue:
add bx,cx;
jmp start;
jmp end;
end:
mov ah,4ch;
mov al,00;
int 21h;
Should I change compilers? It seems like division should be standard. Do I need to read two tutorials (one on NASM, and one on x86?). Any specific help on this problem?
