linux nasm程序集隔离字符串中的字符

Question

如果我有一个声明如下的字符串：

message db "ABCDEFGHIJ",0

如何创建一个指针，允许我指向此字符串中的特定字符，例如“A”字符。而且，我怎么能创建一个允许我增加指针的循环，结果循环遍历整个字符串？

    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:
