linux nasm程序集隔离字符串中的字符

Question

If I had a string declared like this: 如果我有这样声明的字符串：

message db "ABCDEFGHIJ",0

how could I create a pointer that would allow me to point to a specific character in this string, such as the 'A' character. 如何创建一个指针，使我可以指向该字符串中的特定字符，例如'A'字符。 And also, how could I create a loop that would allow me to increment the pointer and as a result, cycle through the entire string? 而且，如何创建一个循环，使我可以增加指针，从而循环遍历整个字符串？

Answer 1

    mov ecx, message ; Masm would use "offset"
top:
    mov al, [ecx] ; get a character
    inc ecx  ; get ready for next one
    cmp al, 0  ; end of string?
    jz done
; do something intelligent with al
    jmp top
done:
