How to loop in assembly language - loops

Question

How would I calculate the first 12 values in the Fibonacci number sequence and be able to place it in EAX reg. and display calling DumpRegs? Using Indirect addressing I know I need a for loop here but I'm not sure how to even go about this. Any help or tips are appreciated.
INCLUDE Irvine32.inc
; (insert symbol definitions here)
.data
; (insert variables here)
Fibonacci BYTE 1, 1, 10 DUP (?)
.code
main PROC
; (insert executable instructions here)
; (This below will show hexa contents of string.)
mov esi, OFFSET Fibonacci ; offset the variables
mov ebx,1 ; byte format
mov ecx, SIZEOF Fibonacci ; counter
call dumpMem
exit ; exit to operating system
main ENDP
; (insert additional procedures here)
END main

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

Answer 2

You determined that you need a for loop to achieve your goal, so maybe the C implementation of the for loop, in assembly, will help you:
Code Generation for For Loop
for (i=0; i < 100; i++)
{
. . .
}
* Data Register D2 is used to implement i.
* Set D2 to zero (i=0)
CLR.L D2
L1
. . .
* Increment i for (i++)
ADDQ.L #1, D2
* Check for the for loop exit condition ( i < 100)
CMPI.L #100, D2
* Branch to the beginning of for loop if less than flag is set
BLT.S L1

.model small
.stack 100h
.data
msg db 'Enter height of the square form 1-9: $'
hash db '#$'
height db 1
length db 0
ctr dw 0
msgagain db 13,10,'Do you want to repeat the program? $'
msgend db 13,10,'Program Terminated! Press any key to exit..$'
.code
mov ax, #data
mov ds, ax
REPEAT:
mov ax, 03
int 10h
mov ah, 09
lea dx, msg
int 21h
mov ah, 01
int 21h
cmp al, '1'
jl REPEAT
cmp al, '9'
jg REPEAT
sub al, 48
mov length, al
mov bl, 1
mul bl
mov height, 1
mov di, 1
mov ctr, ax
mov cx, ax
nextline:
dec length
mov ah, 02
mov bh, 00
mov dl, length
mov dh, height
int 10h
mov cx, di
hashtags:
mov ah, 09
lea dx, hash
int 21h
loop hashtags
