068.宏函数的使用

include Macros.inc

if IsDefined( RealMode )
	include irvine16.inc
else
	include irvine32.inc
endif

.code
	main PROC
		startup
		mWrite <"This program can be assembled to run ",0dh,0ah>
		mWrite <"in both Real mode and Protected mode.",0dh,0ah>
		call WaitMsg
		exit
	main ENDP
END main

当然也可以把mWrite宏所需要的参数写在一行如：

mWrite <"This program can be assembled to run in both Real mode and Protected mode.",0dh,0ah>

这样一来可以使得代码可读性更好，不过要注意的是，mWirte宏是以检测0dh,0ah来判断一个字符串的末尾的。所以如果在字符串当中给出这两个标志结束的编码就会导致错误。
