Whats wrong with this code?

IF \"%language%\" == \"de\" (
    goto languageDE
) ELSE (
    IF \"%language%\" == \"en\" (
    goto languageEN
) ELSE (
    ech         


        

Answer 1

@echo off
title Test

echo Select a language. (de/en)
set /p language=

IF /i "%language%"=="de" goto languageDE
IF /i "%language%"=="en" goto languageEN

echo Not found.
goto commonexit

:languageDE
echo German
goto commonexit

:languageEN
echo English
goto commonexit

:commonexit
pause

The point is that batch simply continues through instructions, line by line until it reaches a goto, exit or end-of-file. It has no concept of sections to control flow.

Hence, entering de would jump to :languagede then simply continue executing instructions until the file ends, showing de then en then not found.
