General ⇒ \label placement

[drowsy]

Hi,

I have seen this a few times:

\begin{theorem\label{mylabel}}
$2+2=4$.
\end{theorem}

and it does work.
Is it OK to do this? I mean, is this behavior official/will be always supported? Looks kinda weird to me to put a label inside of \begin{something}.

This is not a reliable method of placing labels. For some structures it works, but in the most cases not. In this case you better place the label right behind the beginning of the environment.

Code: Select all

\begin{theorem}\label{thm:label}
  % theorem contents
\end{theorem}

Best regards
Thorsten
