首先推荐一本书：WINDOWS汇编语言及系统程序设计 张豫夫 曹建文 译
英文名：WINDOWS ASSEMBLY LANGUAGE & SYSTEMS PROGRAMMING
16- and 32-bit low-level programming for the PC and Windows
by Barry Kauler
这本书比罗云彬那本强，罗云彬那本满篇的高级语法，这本书没有，更高级的是它还有面向对象的编程，用C++等高级的面向对象的语言，若不会asm的oop，我怎吗说这些人呢？
暂这选一例：
这个程序最令人激动之处在于它仅仅使用最普通的 BIOS 和 DOS 视频服务生成了这个
窗口,且丝毫也没有与 Windows产生冲突。这个窗口完全是我们的私有财产,以至 Windows
根本不会意识到它的存在。
它的代码如下：
;DPMI.ASM
;This demo program is written in TASM v3.0.
;It uses the WINASMOO.INC OO-file developed in Chapter 7.
;This program makes use of DPMI & low-level Windows functions.
;This program relates to discussion in Chapter 9.
;remember that Windows funcs only preserve SI,DI,BP & DS.
INCLUDE WINDOWS.INC
INCLUDE WINASMOO.INC
IDM_QUIT EQU 100
IDM_ABOUT EQU 101
