Please correct my code for me i am lost.
Thanks. i submitted pictures yesterday.
; COMSC-142 'Happy Visage' in Assembly Language
; STARTER CODE
; my name
; Define the system call and I/O ** constants **
; to make code more readable farther below
SYS_WRITE equ 1 ; write text to stdout
SYS_EXIT equ 60 ; terminate the program
STDIN equ 0 ; standard input
STDOUT equ 1 ; standard output
; INSTRUCTIONS: REPLACE THE ??????????? (question marks)
; IN THE REST OF THIS PROGRAM WITH WHAT IS
; NEEDED TO MAKE IT RUN.
section .data ; The data section is where we define
; some of our inputs/data
; that we are going to use

len1 equ $ - msg1 ; define len in RAM

; do not add any other len statements
global _start ; The code always resides in the _start(s).
section .text ; strangely, this is the executable part of

; section .code would have made better sense?
_start: ; underscore _start is required on Windows,
; but it is only start on Linux (no _ character)
; with assembler, we have to tell it every little thing
; so we have to code a few lines below with every little thing
; The system is then setup and can put our Happy Visage up
mov rdx, ???? ; put the length into the rdx register
mov rsi, ???? ; put the location of the first message into rsi
mov rdi, ?????? ; put the stdout identifier into rdi
mov rax, ????????? ; put the sys_write into rax to tell the
; system what you want it to do...
; ... which is the write/print something
; The call is almost always put...
; ... into the rax register.
; now we have setup everything above,
; time to put it up on the console by making the syscall
syscall ; syscall to the write() function
; similar to the printf function
xor edi, edi ; Clear edi to indicate successful exit = 0
mov rax, SYS_EXIT ; put the sys_exit identifier into rax
syscall ; call the system to let it know you are done.
