在 masm32.inc 中有这样几个函数的声明:

byt2bin_ex  PROTO :BYTE, :DWORD
wrd2bin_ex  PROTO :WORD, :DWORD
dw2bin_ex   PROTO :DWORD, :DWORD
dw2hex_ex   PROTO :DWORD, :DWORD
bin2byte_ex PROTO :DWORD

学习查看二进制是为了看到 EFLAGS 中的二进制位的变化:

; Test19_6.asm
.386
.model flat, stdcall

include    windows.inc
include    kernel32.inc
include    masm32.inc
include    debug.inc
includelib kernel32.lib
includelib masm32.lib
includelib debug.lib

.data
    szBin db 8 dup(?), 0
.code
main proc
    lahf  ;LAHF 指令是把 EFLAGS 寄存器的低字节读入 AH
    invoke byt2bin_ex, ah, addr szBin
    PrintString szBin  ;01000110
    ret
main endp
end main
