I'm interesting on how to easily operate with arrays in fasm? I think that asm has way to do it without macros. In detail, i'm interesting of how to use twodimensional array. I just need something like this:
mov arr[esi][edi],al
But I havent discovered this feature in fasm yet Sad
Thanks beforehand.

You can write mov [arr+esi+edi], al

i always learned that i can't do this such an elegently style. Cause i need t multiply edi by size of row. But i can multiply it only on 1,2,4,8. So this question is no more actual...

That is because the scale of the sib has only 2^2 values or 1/2/4/8. You cannot do anything about it except to use more than one opcodes.
