Thank you again, that should be enough for most of my small examples.
I guess I never heard of or forgot about \placesidebyside as well as \placeontopofeachother.

But I’d like to show a lot of similar examples to explain several options.
Therefore, if I’d like to simplify my code, but this doesn’t work:

\def\CodeExample#1{%
\startbuffer[zB]
#1
\stopbuffer
\typebuffer[zB]
\getbuffer[zB]
}

\CodeExample{\framed[frame=off,leftframe=on,rulethickness=1em,framecolor=blue]{Klotz am Bein}}


Compilation just stops, maybe some infinite loop?

Simpler:

\def\CodeExample#1{%
\startTEX
#1
\stopTEX
#1
}


Stops with the error:
Use of \m_syst_action_yes doesn't match its definition
