# TeX/endinput

< TeX

## SynopsisEdit

   \endinput


## DescriptionEdit

• This command terminates the input process in the middle of a file. It is redundant at the end of a file.
• On encountering this command, TeX continues reading until the end of the line. This makes it possible to wrap \endinput in an \if oneliner.

## ExampleEdit

  \def\false{false}
\def\students{false}

% Questions, for teachers and students ...

\ifx\students\true\endinput\fi

% Answers, for teacher only


If the \if statement cannot be a oneliner (for legibility reasons, say), then one can use \expandafter:

  \ifx\students\true
% ... various other statements ...
\expandafter\endinput
\fi
