%
% \subsection{Font Size of Locant Numbers}
% \changes{v2.01}{2001/06/20}{New command: \cs{locantnumsize}}
%
% To change the font size of locant numbers, we can use 
% |\locantnumsize|, into which a size command (|\scriptsize| etc.)
% is introduced by using the |\let| command. 
% The default setting is |\scriptsize| as follows: 
%
% \begin{macro}{\locantnumsize}
%    \begin{macrocode}
\let\locantnumsize=\scriptsize
%    \end{macrocode}
% \end{macro}
%
% \subsection{Bond indicators for vertical formulas}
%
% \begin{macro}{\dbloocant}
% \begin{macro}{\dblocant}
% The macro |\dbloocant| is used to designate six edges (inner double bonds) 
% of a six-membered ring.  Any character can be asigned to the respective 
% bond.  
% The macro |\dblocant| provides a fixed set of aliphabetical charactors 
% on the six edges.
