Answer 1

You can make a loop like this:

mov ecx,12
your_label:
; your code
loop your_label

The loop instruction decrements ecx and jumps to the specified label unless ecx is equal to zero. You could also construct the same loop like this:

mov ecx,12
your_label:
; your code
dec ecx
jnz your_label
