如何使用PCMAC.INC显示日期

Question

我想制作一个显示日期（月，日，年）的程序。月份和日期显示正确，但是年份很糟糕。请注意，寄存器dh =月，dl =日，cx =年。这里是我的代码：

INCLUDE PCMAC.INC 
    .MODEL SMALL 
    .586 
    .STACK 100h 

    .DATA 
Message DB 'Today is $' 
Slash DB '/' 
Month DW ? 
Day DW ? 
Year DW ? 

    .CODE 
    EXTRN PutDec : NEAR 
Hello PROC 
    _Begin 
    _GetDate 

    mov al, dh 
    mov ah, 0 
    call PutDec 

    mov al, dl 
    mov ah, 0 
    call PutDec 

    mov ax, cx 
    mov ah, 0 
    call PutDec 

    _Exit 0; 
Hello ENDP 
    END Hello;
