I edited DOSBox configuration to do the following:

[autoexec]
# Lines in this section will be run at startup.
rem @echo=off

mount c C:\DosGames
c:\

:menu
cls
echo 1.temp1
echo 2.temp2
echo 3.temp3
echo 4.exit
set /p choice="select a number between 1 and 3"

if "%choice%"=="1" goto temp1
if "%choice%"=="2" goto temp2
if "%choice%"=="3" goto temp3
if "%choice%"=="4" goto exit
echo Error: Invalid choice.
pause
goto menu

:temp1
echo 1
pause
goto exit

:temp2
echo 2
pause
goto exit

:temp3
echo 3
pause
goto exit

:exit
exit

The system hangs with the "Error: Invalid choice" pause, and doesnt wait for any input.
Help please! 😢
