I’m new to assembly language programming and currently working on a simple program that prompts the user to enter a string, then reverses and displays it. However, I’m struggling to figure out how to display the message “The reversed string is:” and the reversed string on the same line.

Here’s my current code:

section .bss
    buffer resb 100
    reversed_buffer resb 100

section .data
    msg db "Please enter a string: ", 0
    msgLen equ $ - msg
    reverse_msg db "The reversed string is: ", 0
    reverse_msg_len equ $ - reverse_msg

section .text
    global _start

_start:
    mov eax, 4
    mov ebx, 1
    mov ecx, msg
    mov edx, msgLen
    int 0x80

    mov eax, 3
    mov ebx, 0
    mov ecx, buffer
    mov edx, 100
    int 0x80
    mov esi, eax

    mov ecx, esi
    dec ecx
    mov esi, buffer
    mov edi, reversed_buffer

reverse_loop:
    cmp ecx, 0
    jl end_reverse
    mov al, [esi + ecx]
    mov [edi], al
    inc edi
    dec ecx
    jmp reverse_loop

end_reverse:
    mov eax, 4
    mov ebx, 1
    mov ecx, reverse_msg
    mov edx, reverse_msg_len
    int 0x80

    mov eax, 4
    mov ebx, 1
    mov ecx, reversed_buffer
    mov edx, esi
    int 0x80

    mov eax, 1
    xor ebx, ebx
    int 0x80

Could someone guide me on how to modify this code so that the message “The reversed string is:” and the reversed string are displayed on the same line?

Thanks in advance for any help or suggestions!
