If executed from outside a batch script, it will quit CMD.EXE exitCode specifies a numeric number. if /B is specified, sets ERRORLEVEL that number. If quitting CMD.EXE, sets the process exit code with that number.exitCode可以通過系統變數ERRORLEVEL取得注意2:函數和標籤的定義一樣,只是調用方式不一樣。函數用call:+函數名的形式,比如call:function1。標籤使用goto LabelEnd的形式。函數還有可以傳遞參數比如:call:function4 robin,而標籤不行。函數調用有傳回值,而標籤沒有。
