我试图使一个密码检查器在tasm 16位，但它不工作。

.model small
.stack 100h

.data
    missmatch db 'Mismatch at position: ','$'
    password db 'mypassword',10,'$'   ; stored password
    prompt db 'Enter password:',0
    try_again db 'Incorrect password. ',0
    try_again2 db 'You have ',0
    try_again3 db ' tries left.','$'
    correctmsg db 'Correct password','$'
    incorrect db 'Too many incorrect attempts, exiting',0
    newline db 13,10,'$'
    input db 100 dup('$')   ; buffer to store input
    tries db 3   ; number of tries remaining
    indx db 0;
    pos db 3 dup(0)
.code

    mov ax, @data
    mov ds,ax
    mov byte ptr [input],0
    mov bx,0 ;valoarea 0 este pentru tastatura

    mov si, offset input   ; load the offset of the first string into si
    mov di, offset password   ; load the offset of the second string into di

    
next_char:
    mov al,[si]    ; move the value of the current character in the first string to al
    cmp al,0   ; check if the current char is a null terminator
    je correct ; if it is, we have reached the end of the first string
    mov ah,[di] ; move the value of the current character in the second string to ah
    cmp al,ah  ; compare the values of al and ah
    jne failed  ; if they are not equal, jump to the failed label

程序应该从键盘上读取密码，并检查是否与程序中保存的密码匹配，用户有3次尝试。有人能帮我吗？
