Hi, I recently started programming with inline assembly (I use Visual C++), but I have found a bug that I cannot solve.
Why does it give an error?

// C language
unsigned char array[] = {1, 2, 3, 4, 5, 6, 7};

// Assembly
__asm
{
XOR CL,CL

MOV AL,array[0] ; ok
MOV AL, array+2 ; ok

MOV AL,array[CL] ; ERROR!!!
}

The error is -> "error C2403: 'CL' : register must be base/index in 'second operand'".

I tested it many times and I found that the only way to make it work is to use ECX register as index! Why?
If I use ANY OTHER register it will not compile (as above) or it will give a Fatal Error if I use another EXX register (as EAX or EBX).
The problem is that on my program I have a "nested for loop" and so I can't use just 1 counter (ECX), but I need 2 of them and they must be BYTE register (as CL/CH) because the array variable is a char. Any idea?

Thank you very much!
Luke

P.S: any better idea on how to write effective inline nested loop?

I guess in your rush to spam multiple message boards

with the same question, that you couldn't be bothered with simple courtesy of reading the posting guidelines on any of them.

Yes, you are completely right...
The problem is that I have less than 2 days to finish the project for my Computer Science school and when I posted that, I was really running mad (I worked for so many days and moreover it was 03:00 of night here in Italy!!!), so I decided to find an Assembly forum to ask for help! I still don't understand why it does not compile , I really need help...

I am very sorry
Luke

P.S: since I can no more edit my first post, here the is the code (for the problem, look at the first post):
