帮我改一段程序

.386
.model flat,stdcall
option casemap:none

include      windows.inc
include      kernel32.inc
includelib   kernel32.lib
include      user32.inc
includelib   user32.lib

              .data
MsgBoxCaption  db "结果！",0
MsgBoxText     db 0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0

              .code
start:
        mov   al,97h
        call  ShowAL


        invoke MessageBox, NULL, addr MsgBoxText, addr MsgBoxCaption, MB_YESNOCANCEL
        invoke ExitProcess, NULL

ShowAL proc
        mov  dl,al      ;保存AL
        mov  cl,04      
         shr  al,cl      ;AL高4位移至低4位
         xor  ebx,ebx
         mov  esi,offset MsgBoxText

        .while  ebx < 2
             add al,30h
             mov [esi+ebx],al
             inc  ebx
             mov al,dl
             and al,0fh
 
        .endw
         ret
ShowAL   endp

end start
;===========================================
这是我的修改，我不用它的循环了，自己搞了一个：
.while   x<n
    ;do something
    inc  x
.endw
