彻底删除 scrlttr2 中的 refline

Question

我想使用 KOMA 变量，myref但我不想refline在我的文档中出现（因为我打算把 放在myref其他地方）。但是，refline=false似乎没有效果。我怎样才能让 refline 完全消失？

MWE（参考线未消失）：

\documentclass{scrlttr2}
\usepackage[british]{babel}
\setkomavar{myref}{letterone}
%\KOMAoptions{refline=false} %%This does NOT WORK
\begin{document}

\begin{letter}{Mrs Mabel Canary\\24 The Street\\Some Village\\
Some Town\\Noshire\\AB1 2YZ}
  \opening{Dear Mrs~Canary}

  This is an imaginary letter.

  This is the second paragraph of the letter.

  \closing{Yours sincerely}

  \ps PS: this is a postscript.

  \encl{Photocopy of something interesting\\
   Photocopy of something rather dull}

  \cc{Prof Important Person\\
   Dr Bor Ing}
\end{letter}

\end{document}

Answer 1

用于\removereffields从 refline 中删除除日期之外的所有字段：

\documentclass{scrlttr2}
\usepackage[british]{babel}
\setkomavar{myref}{letterone}
\removereffields% <- added

\begin{document}

\begin{letter}{Mrs Mabel Canary\\24 The Street\\Some Village\\
Some Town\\Noshire\\AB1 2YZ}
  \opening{Dear Mrs~Canary}

  This is an imaginary letter.

  This is the second paragraph of the letter.

  \closing{Yours sincerely}

  \ps PS: this is a postscript.

  \encl{Photocopy of something interesting\\
   Photocopy of something rather dull}

  \cc{Prof Important Person\\
   Dr Bor Ing}
\end{letter}

\end{document}
