% \section{Substitution Bond Coloring}
%
% \begin{macro}{\ifcolorBLsw}
% A switch |\ifcolorBLsw| is introduced to judging whether the present process 
% is in BONDLIST or in ATOMLIST.  
% 
%    \begin{macrocode}
\newif\ifcolorBLsw \colorBLswfalse
%    \end{macrocode}
% \end{macro}
% 
% The macro |\RightAtomBond| is defined to color substitution bonds (and substituents), 
% when it is to be designated in ATOMLIST or in BONDLIST of a command for drawing 
% a structural formula.  
%
% \begin{verbatim}
%   \RightAtomBond(x,y)[COLOR]&lt;CLIPPING&gt;{SUBSTLIST}
% \end{verbatim}
%
% The first optional argument (x,y) represents increments of x-, and y-coordinates, 
% which may be added if adjustment is necessary. The default value is (0,0). 
% The second optional argument [COLOR] is a command of coloring (e.g., |\red|). 
% The default value is |\black|. 
% The third optional argument &lt;CLIPPING&gt; accomodates \verb/&lt;s&gt;/ for non-clipping and 
% a vacant or omitted argument represents a clipping of a corner. 
% The defalt value is a vacant value. 
% The fourth argument is a SUBSLIST, in which a substitution number 1--8 represents 
% a bond slope to be drawn. Slopes to cover a right-handed half circle are numbered 
% on a similar line to those of the |\ryl| macro, as follows: 
% \begin{verbatim}
%     SLOPE    
%       
%       1      : (0,1)
%       2      : (3,5)

%       6      : (1,-1)
%       7      : (3,-5)
%       8      : (0,-1)
% \end{verbatim}
% As for the format of the SUBSLIST, see the specification of the |\ryl| command.
