汇编语言实例:封装器


现在创建一个简短的程序 Wraps.asm 来展示之前已介绍的作为过程封装器的宏。由于每个宏都隐含了大量繁琐的参数传递,因此程序出奇得紧凑。假设这里所有的宏当前都在 Macros.inc 文件内:
; 过程封装器宏        (Wraps.asm)
; 本程序演示宏作为库过程的封装器。
; 内容: mGotoxy, mWrite, mWriteString, mReadString, 和 mDumpMem.
INCLUDE Irvine32.inc
INCLUDE Macros.inc            ; 宏定义

.data
array DWORD 1,2,3,4,5,6,7,8
firstName BYTE 31 DUP(?)
lastName  BYTE 31 DUP(?)

.code
main PROC
    mGotoxy 0,0
    mWrite <"Sample Macro Program",0dh,0ah>

; 输入用户名
    mGotoxy 0,5
    mWrite "Please enter your first name: "
    mReadString firstName
    call Crlf

    mWrite "Please enter your last name: "
    mReadString lastName
    call Crlf

; 显示用户名
    mWrite "Your name is "
    mWriteString firstName
    mWriteSpace
    mWriteString lastName
    call Crlf

; 显示整数数组
    mDumpMem OFFSET array,LENGTHOF array, TYPE array
    exit
main ENDP
END main
