Question

This is an assembly program, we are tasked with converting a string to a int, the string has values base 14, and the integer will be base 10.

I have the following code but i get this error, error: label or instruction expected at start of line in line 49 with the jae 9lp. How do i fix this or why does it happen?

section .data
; -----
; Define constants
NULL equ 0
EXIT_SUCCESS equ 0
; successful operation
SYS_exit equ    60
SPACE equ     " "
max_length   dd 10

rsum dd 0
dig     dd 0
ten db 10
intNum dd   0
fourteen dd 14
strNum   db "1a7C",NULL
  
   section .text
global _start
_start:

   mov ecx, dword[max_length]
   ;; get string address
   mov al ,       strNum
   ;; i = 0
   mov rsi, 0
   mov rbx, 0
  
Nxtchr:             ;gets next character
   mov al, byte[rbx    + rsi *1] ; chr (ch = str[i])
   cmp al, SPACE              ;if (ch != " "), go to Nxtstp
   jne Nxtstp

   inc rsi           ;i++
   loop Nxtchr       ;go to Nxtchr

   mov ecx, dword[max_length]
   mov r8d, 0
  
Nxtstp:               ;next step to get int value
   mov al, byte[rbx    + rsi *1]   ;chr (ch = str[i])
   mov bl, NULL
   cmp al ,bl
   je Exitlp; if ( ch == NULL), exit l
   cmp al , "0"       ;if (ch is between "0" and "9")
   jae 9lp

9lp:
   cmp al , "9"
   ja aLP
   sub al, "0"
   mov byte[ dig], al   ; dig = ch - "0"

aLP:
   cmp al ,"a"       ;if (ch is between "a" and "d")
   jae dLP

dLP:
   cmp al, "d"
   ja ALP
   sub al, "a"
   add al,byte[ ten]   ;dig = ch -"a" +10
   mov byte[ dig], al

ALP:
   cmp al , "A"          ;;if (ch is between "A" and "D"
   jge DLP

DLP:
   sub al, "A"       ;;dig = ch -"A" +10
   add al,byte [ ten]
   mov byte[dig], al

   mov eax, dword [ rsum]   ;running sum = rsum * 14
   mul fourteen
   movzx   eax, byte[dig]
   add eax,byte[ dig]   ;running sum = rsum +dig
   mov dword[ rsum], eax

   inc r8d
   loop Nxtstp

Exitlp:  
   mov eax,dword[ rsum]
   mov dword[intNum], eax

last:
mov rax, SYS_exit
mov rdi, EXIT_SUCCESS
syscall

Explanation / Answer

Everything is fine in Code.

Change name of 9lp to something else like elp and then exeute.

You will not face the error
