批处理命令三综合运用

1,交互式案例：

@echo off
cls
title Repairing function
:menu
cls
color 0A
echo.
echo              ==================================================

echo              Q.exit
echo.
echo.
:cho
set choice=
set /p choice=     please choice:
if not "%choice%"=="" set choice=%choice:~0,1%
if /i "%choice%"=="1" goto ip
if /i "%choice%"=="2" goto setsave
if /i "%choice%"=="3" goto kaiji
if /i "%choice%"=="4" goto clean
if /i "%choice%"=="Q" goto endd
echo The selection is invalid. Please re-enter
echo.
goto cho
 

2,if语句综合运用

@echo off
set sum=0
call :sub sum 10 20 35
echo result:%sum%
pause

:sub
rem 参数1为返回变量名称
set /a %1=%1+%2
shift /2
if not "%2"=="" goto sub
goto :eof

:: 求和
::shift /n 从第n个参数开始移位
