汇编语言 (Irvine) - 等待击键和 returns 按下的键的宏

Question

等待击键的宏和 returns 被按下的键。宏应包含 ASCII 码和键盘扫描码的参数。

我有以下代码，但出现两个错误。错误在下面，下面是我的源代码。

错误：

error A2006: undefined syV

error MSB3721: The command "ml.exe /c /nologo /Zi /Fo"Debug\ch10_01.obj" /Fl"zprob1.lst" /I "c:\Irvine" /W3 /errorReport:prompt /Ta"....\ASM Solutions\ch10\ch10_01.asm"" exited with code 1

源代码：

 INCLUDE Irvine16.inc
ASSUME DS:_DATA

mReadkey MACRO ascii, scan
    mov ah,10h      ; BIOS keyboard input function
    int 16h
    mov scan,ah
    mov ascii,al
ENDM

.data
ascii BYTE ?
scan  BYTE ?
str1  BYTE "ASCII code: ",0
str2  BYTE "Scan code:  ",0

.code
main PROC
mov ax,@data
mov ds,ax

; Wait for a key; when the macro returns, the two arguments
; contain the ASCII code and scan code of the key.
mReadkey ascii, scan

; Display the values.
    mov edx,OFFSET str1
    call WriteString
    movzx eax,ascii
    call WriteHex
    call Crlf

    mov edx,OFFSET str2
    call WriteString
    movzx eax,scan
    call WriteHex
    call Crlf

    exit
main ENDP
END main

您试图将 16 位实模式代码编译为 32 位保护模式可执行文件。那行不通的。在ml.exe的命令行中添加一个/omf并确保link16.exe将用作链接器。
