Thanks to all of you for your hints and comments!
I thought \l does work, why \L does not.
To type \L is faster than changing the keyboard language when I write in German normally.


1. Hans made a while ago the decision to reduce the number of commands to output certain characters and create accented characters. To still be able to create them he added the \with... commands.

2. The reason why \L doesn't produce Ł are the following lines from chem-str.mkxl which nils the values of all listed commands.

\permanent\let\X\relax
\permanent\let\T\relax
\permanent\let\B\relax
\permanent\let\L\relax
\permanent\let\M\relax
\permanent\let\R\relax

The same thing happens for the \CC commands which gets reset in tabl-com.mkxl

\permanent\protected\lettonothing\CC
