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

Recommendation   Do not use user-added REM statements to block batch steps   Use conditional GOTO instead  That way you can predefine and test the steps and options   The users also get much simpler changes and better confidence    Echo on rem Using flags to control command execution  SET ExecuteSection1 0 SET ExecuteSection2 1   echo off  IF  ExecuteSection1   0 GOTO EndSection1 ECHO Section 1 Here   EndSection1  IF  ExecuteSection2   0 GOTO EndSection2 ECHO Section 2 Here  EndSection2

batchfiles perform simple string substitution with variables  so  a simple  goto  language language  echo notfound       does this without any need for if
