CrLf

16 进制查表法：

@echo off&setlocal enabledelayedexpansion
set num=42

set n=0
for %%a in (0 1) do for %%b in (0 1) do for %%c in (0 1) do for %%d in (0 1) do (
	set _!n!=%%a%%b%%c%%d&set /a n+=1
)
rem 创建 0~15 的表

for /l %%a in (28 -4 0) do (
	set /a "m=num>>%%a&15"
	for %%b in (!m!) do set /p=!_%%b!<nul
)
echo;
rem 位运算分别获取相应位的值，并查表
