if %errorlevel%==1 goto save1

if %errorlevel%==3 set /a data-=100 & goto menu
if %errorlevel%==4 set /a data+=100 & goto menu
if %errorlevel%==5 goto erasefile
:save1
cls
echo Saving...
timeout /t 1 /nobreak >nul
goto save2
:save2
cls
echo ::File auto generated at %time% %date% >>SaveData.bat
cls
echo set /a data=0 >> SaveData.bat
cls
echo set /a data+=%data% >>SaveData.bat
cls
goto menu
:load
cls
if not exist SaveData.bat cls & echo No save data has been saved. & timeout /t 1 /nobreak >nul & goto menu
cls
if exist SaveData.bat call SaveData.bat
cls
echo File loaded! & timeout /t 1 /nobreak >nul & goto menu
:erasefile
if exist SaveData.bat del SaveData.bat & cls & echo Save file deleted. & timeout /t 1 /nobreak >nul & goto menu
if not exist SaveData.bat cls & echo No save file to delete. & timeout /t 1 /nobreak >nul & goto menu
