newwrite：将文本添加到现有的输出文件

Question

我有

\documentclass[a4paper]{article}
\begin{document}
\newwrite\myoutfile
\immediate\openout\myoutfile=\jobname-myoutfile.txt
\immediate\write\myoutfile{
aaa
}
\immediate\closeout\myoutfile

\section{Test: Input the Result}
\input{\jobname-myoutfile.txt}
\end{document}

这给了我外部jobname-myoutfile.txt文件

aaa

里面。

我怎样才能bbb向输出文件添加新文本（例如（以换行符！））？

这样我就会有

aaa
bbb

Answer 1

它应该像

\documentclass[a4paper]{article}

\begin{document}
\newwrite\myoutfile
\immediate\openout\myoutfile=\jobname-myoutfile.txt
\immediate\write\myoutfile{
aaa
}

\immediate\write\myoutfile{
bbb
}

\immediate\closeout\myoutfile


\section{Test: Input the Result}
\input{\jobname-myoutfile.txt}
\end{document}
