\section{Drawing Vertical Forms}
\subsection{Commands for Specified Use}

The macro \verb/\quinolinev/ is used to draw 
quinoline derivatives of vertical type (hetarom.sty). 
Macros for drawing other fused heterocycles are also defined. 
The formats of these commands are as follows: 
\begin{verbatim}
   \quinolinev[BONDLIST]{SUBSLIST}
   \isoquinolinev[BONDLIST]{SUBSLIST}
   \quinoxalinev[BONDLIST]{SUBSLIST}
   \quinazolinev[BONDLIST]{SUBSLIST}
   \cinnolinev[BONDLIST]{SUBSLIST}
   \pteridinev[BONDLIST]{SUBSLIST}
\end{verbatim}

% * heterocycles having two fused six-membered rings *
% *  (vertical type)                                 *

Locant numbers for designating substitution positions 
as well as bond descriptors for setting double bonds 
are shown in the following diagram:

\end{xymspec}
The handedness for each oriented or double-sided position 
is shown with a character set in parentheses. 
Each character in the optional argument BONDLIST specifies 
an inner (endocyclic) double bond as shown in Table \ref{tt:f1}.
\begin{table}[hpbt]

            & \\

\end{tabular}
\end{center}
\end{table}

The argument SUBSLIST is employed to specify each substituent with 
a locant number and a bond modifier shown in Table \ref{tt:a2}, 
in which $n$ is an arabic numeral between 1 and 8. 
Sibstitution on  9 (4a position) or 10 (8a position) can 
be assigned in the same way.

\begin{verbatim}
   \quinolinev{2==CN} \qquad
   \isoquinolinev{1==CN}\qquad
   \quinoxalinev{2==CH$_{3}$;3==CH$_{3}$} \par

   \cinnolinev{4==Cl;3==Cl} \qquad
   \pteridinev{2==F}
\end{center}

The macro \verb/\quinolinevi/ is used to draw 
quinoline derivatives of inverse vertical type (hetarom.sty). 
Macros for depicting other fused heterocycles are also defined. 
The formats of these commands are as follows: 
\begin{verbatim}

   \isoquinolinevi[BONDLIST]{SUBSLIST}
   \quinazolinevi[BONDLIST]{SUBSLIST}

\subsection{Commands for General Use}
Such commands as \verb/\quinolinev/ (for specified use) 
are based on the macro \verb/\decaheterov/, 
which is generally used to draw 
six-six-fused heterocycles of vertical type (hetarom.sty). 
\begin{verbatim}
   \decaheterov[BONDLIST]{ATOMLIST}{SUBSLIST}

                   $\bullet$: (\the\noshift,\the\noshift)}}
\end{xymspec}
The handedness for each oriented or double-sided position 
is shown with a character set in parentheses. 
The optional argument BONDLIST is used to specify a bond pattern 
as shown in Table \ref{tt:f1}. Note that the default structure 
is the fully unsaturated one.

The argument ATOMLIST has a similar format for positions of 
$n$ = 1 to 8.  A hetero-atom on the 4a-position is 
designated to be 4a==N or 9==N; 
and a hetero-atom on the 8a-position is given as to be 
8a==N or \{\{10\}\}==N.

The argument SUBSLIST for this macro takes a general format, 
in which the modifiers listed in Table \ref{tt:a2} are used. 
Note that 9 and 10 should be used for designating 
4a and 8a positions. 

\medskip
\noindent
Example:
\begin{verbatim}
\decaheterov[H]{7==O}{6D==O;9A==H;{{10}A}==CH=CH$_{2}$}
\decaheterov[H]{5==O}{9==OH;{{10}}==OH}
\decaheterov[ch]{1==O}{9A==\lmoiety{HOCH$_{2}$};{{10}A}==H;%
4==CH$_{3}$;7==H$_{3}$C}
\end{verbatim}
produce the following structures: 
\begin{center}
\decaheterov[H]{7==O}{6D==O;9A==H;{{10}A}==CH=CH$_{2}$}
\decaheterov[H]{5==O}{9==OH;{{10}}==OH}
\decaheterov[ch]{1==O}{9A==\lmoiety{HOCH$_{2}$};{{10}A}==H;%
4==CH$_{3}$;7==H$_{3}$C}
\end{center}

The command \verb/\decaheterovi/ is the inverse-type macro 
of \verb/\decaheterov/ described above (hetarom.sty). 
\begin{verbatim}
   \decaheterovi[BONDLIST]{ATOMLIST}{SUBSLIST}

Locant numbers for designating substitution positions 
and bond descriptors for typesetting double bonds 
are represented by the following diagram:

                   $\bullet$: (\the\noshift,\the\noshift)}}
\end{xymspec}
The handedness for each oriented or double-sided position 
is shown with a character set in parentheses. 
The optional argument BONDLIST contains a characher string 
selected from Table \ref{tt:f1}.

Example:
\begin{verbatim}
\decaheteroh[H]{7==O}{6D==O;9A==H;{{10}A}==CH$_{2}$=CH}
\decaheteroh[H]{5==O}{9==OH;{{10}}==HO}
\decaheteroh[ch]{1==O}{9A==CH$_{2}$OH;{{10}A}==H;%
4==CH$_{3}$;7==CH$_{3}$}
\end{verbatim}
produce the following structures: 
\begin{center}
\decaheteroh[H]{7==O}{6D==O;9A==H;{{10}A}==CH$_{2}$=CH}
\decaheteroh[H]{5==O}{9==OH;{{10}}==HO}

4==CH$_{3}$;7==CH$_{3}$}

The macro \verb/\decaheterohi/ (carom.sty) is the inverse counterpart of 
\verb/\decaheteroh/.  
The format and the assignment of 
BONDLIST and SUBSLIST of the former macro are the same as the latter 
(see Tables \ref{tt:a2} and \ref{tt:f1}).

   \decaheterohi[BONDLIST]{ATOMLIST}{SUBSLIST}
