+\begin{document}

+\maketitle
+
+This article contains a summary of the \PiCTeX{} commands. This is intended as
+a reminder for users who have read the \PiCTeX{} manual (which is available
+from the LFCS library). The following conventions should be observed when
+using \PiCTeX{} commands:
+\begin{itemize}
+\item
+At least one blank must be present for each blank in the command prototypes
+below.
+\item
+Quantities in \type{<>}'s must be specified as explicit dimensions, or in
+terms of \TeX's dimension registers.
+\item
+\emph{coord}, \emph{xcoord}, \emph{ycoord}, \emph{x}, and \emph{y}, with or
+without subscripts or superscripts denote coordinates with respect to the
+current coordinate system. In particular, they are dimensionless quantities.
+Values must be expressed in fixed point notation, with at most 5 digits to the
+right of the decimal point.
+\item
+Parts of a command enclosed in [\,]'s may be omitted.
+\end{itemize}
+
+\section{Commands}
+The \PiCTeX{} drawing commands are:
+\begin{syntax}
+\item[{\tt\linestack[l]{\bsl accountingoff\\
+\bsl accountingon}}]
+These commands suspend and resume \PiCTeX's updating procedure for the minimum
+size box enclosing the picture. They should only be used when \PiCTeX{} has
+been notified of
+the minimum size box already (e.g.~by executing a \verb+\setplotarea+).
+\item[{\tt\bsl arrow <$\ell$> [$\beta$,$\gamma$]
+{\rm[}<\emph{xshift},\emph{yshift}>{\rm]} from \emph{xcoord}$_s$ \emph{ycoord}$_s$ to \emph{xcoord}$_e$
+\emph{ycoord}$_e$}]
+This command draws an arrow, where (\emph{xcoord}$_s$,\emph{ycoord}$_s$) is the start of the
+line on which the arrow lies, (\emph{xcoord}$_e$,\emph{ycoord}$_e$) is the end of the line
+on which the arrow lies, $\ell$ is the length of the arrowhead, $\beta\ell$ is
+the width of the arrowhead at half its length, and $\gamma\ell$ is the width
+of the arrowhead at its full length. The arrowhead will be open, and will be
+drawn with a smooth curve through the width points and the end of the line.
+The arrowhead will curve in if $2\beta < \gamma$, and curve out if
+$2\beta > \gamma$.
+\type{<\emph{xshift},\emph{yshift}>} has the same effect as in the \verb+\put+ command.
+\item[{\tt\linestack[l]{\bsl axis {\rm[}bottom{\rm]} {\rm[}top{\rm]} {\rm[}left{\rm]} {\rm[}right{\rm]}\\
+\quad{\rm[}shiftedto y=\emph{ycoord}{\rm]} {\rm[}shiftedto x=\emph{xcoord}{\rm]}\\
+\quad{\rm[}visible{\rm]} {\rm[}invisible{\rm]}\\
+\quad{\rm[}label \{\emph{axis label}\}{\rm]}\\

+\quad\quad{\rm[}out{\rm]} {\rm[}in{\rm]}\\
+\quad\quad{\rm[}long{\rm]} {\rm[}short{\rm]} {\rm[}length <\emph{length}>{\rm]}\\

+\emph{dcoord}{\rm]}\\
+\quad\quad\quad{\rm[}at \emph{coord}$_1$ \emph{coord}$_2$ \ldots\ /{\rm]}\\
+\quad/}}]
+This command draws an axis along the \type{bottom}, \type{top}, \type{left},
+or \type{right} edge of the current plot area (one of these keywords must be
+specified).
+The \type{shiftedto} option causes a bottom or top axis to be
+drawn at the specified $y$-coordinate, and a left or right axis to be drawn at
+the specified $x$-coordinate.
+The keyword \type{invisible} suppresses the drawing of the axis, but not of
+tick marks, labels, etc. \type{visible} is the default.
+The text specified by \emph{axis label} is centred with respect to the
+appropriate edge of the plot area.
+\type{ticks} causes tick marks to be drawn on the axis:
+\begin{itemize}
+\item
+Ticks normally point \type{out} from the plot area; \type{in} makes them point
+into the plot area.
+\item
+Ticks are normally \type{long}, but can be made \type{short}, or given an
+arbitrary \emph{length} with the \type{length} option.
+\item
+The \emph{width} of the ticks can be set with the \type{width} option.
+\item
+Ticks can be extended across the whole plot area with the \type{andacross}
+option, making grid lines. The default is \type{butnotacross}, which stops the
+ticks from extending across the plot area.
+\item
+Ticks are normally \type{unlabeled}. If the \type{numbered} option is used,
+the \type{at} or \type{from} options below assign numeric values to them.
+Arbitrary tick labels can be specified by the \type{withvalues} option; the
+labels \emph{value}$_1$, \emph{value}$_2$, \ldots{} are assigned to subsequent ticks until
+the list of values is exhausted or an \type{unlabeled} or \type{numbered}
+keyword is encountered. Values must be separated by at least one blank, and at
+least one blank must precede the `\type{/}' that terminates the list. If a
+value contains a blank or `\type{/}', enclose the entire value in
+\type{\{\}}'s.
+\item
+The option \type{quantity $q$} draws $q$ ticks equally spaced from left to
+right, or from bottom to top. The first and last ticks are at the ends of the
+axis.
+\item
+The \type{from} option draws ticks at the indicated coordinates. \emph{coord}$_s$,
+\emph{coord}$_e$, and \emph{dcoord} must be fixed point numbers, with the same number of
+digits to the right of the decimal point (if any), and \emph{dcoord} must be
+positive. If the \type{numbered} option is in effect, the coordinate of the
+tick is used as the tick label.
+\item
+The \type{at} option draws ticks at the specified coordinates. As with the
+\type{from} option, the coordinates must be fixed point numbers, which are
+used as tick labels if \type{numbered} is in effect. The list of coordinates
+must be terminated by `\type{/}'.
+\item
+The \type{logged} option applies only to the positioning subsequent ticks
+specified by the \type{at} or \type{from} options. Ticks are placed at the
+$\log_{10}$'s of the specified locations; the original unlogged numbers are used
+as labels if \type{numbered} is in effect. \type{unlogged} is the default.
+\end{itemize}
+\item[\tt\bsl beginpicture]
+This command is used to start \PiCTeX{} pictures.
+\item[{\tt\bsl betweenarrows \{\emph{text}\} {\rm[}[{\rm[}$o_x${\rm]}{\rm[}$o_y${\rm]}]{\rm]}
+{\rm[}<\emph{xshift},\emph{yshift}>{\rm]} from \emph{xcoord}$_s$ \emph{ycoord}$_s$ to \emph{xcoord}$_e$
+\emph{ycoord}$_e$}]
+\begin{sloppypar}
+This command centres \emph{text} between a pair of arrows pointing outwards.
+\type{<\emph{xshift},\emph{yshift}>} and \type{[{\rm[}$o_x${\rm]}{\rm[}$o_y${\rm]}]}
+have the same effect as in the \verb+\put+ command.
+(\emph{xcoord}$_s$,\emph{ycoord}$_s$) and (\emph{xcoord}$_e$,\emph{ycoord}$_e$) are the start and end
+coordinates of the arrow pair.
+Either \emph{xcoord}$_s$ and \emph{xcoord}$_e$ should be the
+same, or \emph{ycoord}$_s$ and \emph{ycoord}$_e$ should be the same.
+\end{sloppypar}
+\item[\tt\bsl circulararc $\theta$ degrees from \emph{xcoord}$_s$ \emph{ycoord}$_s$ center
+at \emph{xcoord}$_c$ \emph{ycoord}$_c$]
+This command draws an arc of a circle with a centre at (\emph{xcoord}$_c$,
+\emph{ycoord}$_c$); the arc starts from (\emph{xcoord}$_s$,\emph{ycoord}$_s$) and extends
+anticlockwise through $\theta$ degrees. $\theta$ can have any real value
+between -360 and 360.
+\item[\tt\bsl Divide <\emph{dividend}> by <\emph{divisor}> forming <\emph{quotient}>]
+This is \PiCTeX's division command for dimensions. \emph{dividend} and \emph{divisor}
+may be explicit dimensions or dimension registers; \emph{quotient} must be a
+dimension register.
+\item[\tt\bsl dontsavelinesandcurves]
+This command stops \PiCTeX{} from saving plot locations to a file (see
+\verb+\savelinesandcurves+).
+\item[\tt\bsl ellipticalarc axes ratio $\xi$:$\eta$ $\theta$ degrees from
+\emph{xcoord}$_s$ \emph{ycoord}$_s$ center at \emph{xcoord}$_c$ \emph{ycoord}$_c$]
+This command draws an arc of an ellipse with a centre at (\emph{xcoord}$_c$,
+\emph{ycoord}$_c$); the arc starts from (\emph{xcoord}$_s$,\emph{ycoord}$_s$) and extends
+anticlockwise through $\theta$ degrees. $\xi$ and $\eta$ are numbers
+proportional to the lengths of the horizontal and vertical axes of the ellipse.
+\item[\tt\bsl endpicture]
+This command terminates a \PiCTeX{} picture.
+\item[\tt\bsl endpicturesave <\emph{xreg},\emph{yreg}>]
+This command is used to terminate sub-pictures, saving the left
+edge and baseline in \emph{xreg} and \emph{yreg}.
+If the subpicture is then \verb+\put+ at (\emph{xcoord},\emph{ycoord}) with the options
+`\type{[Bl] <\emph{xreg},\emph{yreg}>}', the reference point of the sub-picture will be
+at (\emph{xcoord},\emph{ycoord}).
+\item[\tt\bsl findlength \{\emph{curve commands}\}]
+\PiCTeX{} executes the curve drawing commands specified and puts the length
+into the dimension register \verb+\totalarclength+. This can be used as the
+$\lambda$ argument to \verb+\setdotsnear+ and \verb+\setdashesnear+.
+\item[{\tt\bsl frame {\rm[}<\emph{separation}>{\rm]} \{\emph{text}\}}]
+This command frames \emph{text}, with an optional border of
+\emph{separation}.
+This command has its normal \LaTeX{} meaning outside of \PiCTeX{} pictures,
+but \verb+\pictexframe+ can be used outside of \PiCTeX{}
+pictures to get the same effect as \PiCTeX's \verb+\frame+.
+\item[\tt\bsl grid \{$c$\} \{$r$\}]
+This command partitions the the plot area in to $c$ columns and $r$ rows.
+\item[\tt\bsl gridlines]
+This command sets the default for the \type{andacross}/\type{butnotacross}
+option of the \type{axis} command to be \type{andacross}.
+\item[{\tt\linestack[l]{\bsl hshade $y_0$ $x_0^{(l)}$ $x_0^{(r)}$ \ldots\
+{\rm[}<$\epsilon_{l;i}$,$\epsilon_{r;i}$,$\epsilon_{d;i}$,$\epsilon_{u;i}$>{\rm]}
+$y_i$ $x_i^{(l)}$ $x_i^{(r)}$ \ldots\ /\\
+\bsl hshade $y_0$ $x_0^{(l)}$ $x_0^{(r)}$ \ldots\
+{\rm[}<$\epsilon_{l;i}$,$\epsilon_{r;i}$,$\epsilon_{d;i}$,$\epsilon_{u;i}$>{\rm]}
+$y_{2i-1}$ $x_{2i-1}^{(l)}$ $x_{2i-1}^{(r)}$ $y_{2i}$ $x_{2i}^{(l)}$
+$x_{2i}^{(r)}$ \ldots\ /}}]
+This command shades a region with piecewise linear/quadratic left and right
+boundaries. Sub-regions are defined by the coordinates ($x_n^{(l)}$,$y_n$),
+($x_n^{(r)}$,$y_n$), ($x_{n+1}^{(r)}$,$y_{n+1}$) and
+($x_{n+1}^{(l)}$,$y_{n+1}$).
+The relations $y_n<y_{n+1}$ and $x_n^{(l)}\leq x_n^{(r)}$
+should hold. For the duration of the shading the optional edge effect field
+`\type{<$\epsilon_{l;i}$,$\epsilon_{r;i}$,$\epsilon_{d;i}$,$\epsilon_{u;i}$>}'
+overrides the specifications made by \verb+\setshadesymbol+. The second form
+should be used when \verb+\setquadratic+ is in effect.
+\item[\tt\bsl inboundscheckoff]
+This command disables checking whether plot symbols are outside the current
+plot area.
+\item[\tt\bsl inboundscheckon]
+This command enables checking whether plot symbols are outside the current
+plot area.
+\item[\tt\bsl invisibleaxes]

+and (\emph{xcoord}$_2$,\emph{ycoord}$_2$), etc.
+\item[\tt\bsl setlinear]
+This command sets the interpolation mode to linear mode. In this mode,
+\verb+\plot+ draws straight lines between coordinates.

+The optional `edge effects' field
+\type{<$\epsilon_{l}$,$\epsilon_{r}$,$\epsilon_{d}$,$\epsilon_{u}$>}
+specifies the distances from the left, right, bottom and top edges within
+which the shade symbol will \emph{not} be placed. 0pt may be specified by
+`\type{z}'.
+\type{<\emph{xshift},\emph{yshift}>} and \type{[{\rm[}$o_x${\rm]}{\rm[}$o_y${\rm]}]}

+automatically.
+\item[{\tt\bsl stack {\rm[}[$o$]{\rm]}
+{\rm[}<\emph{leading}>{\rm]}\{\emph{list}\}}]

+This command causes \PiCTeX{} to rotate lines, curves, shading patterns, and
+\verb+\put+ coordinates by $\theta$ degrees anticlockwise around the point
+($x_p$,$y_p$). The rotation lasts until a \verb+\stoprotation+, or until the
+enclosing group ends.
+\item[\tt\bsl stoprotation]
+This command cancels any rotation in effect.
+\item[\tt\bsl ticksin]
+This command sets the default for the \type{in}/\type{out}
+option of the \type{axis} command to be \type{in}.

+$y_{2i}^{(t)}$ \ldots\ /}}]
+This command shades a region with piecewise linear/quadratic bottom and top
+boundaries. Sub-regions are defined by the coordinates ($x_n$,$y_n^{(b)}$),
+($x_n$,$y_n^{(t)}$), ($x_{n+1}$,$y_{n+1}^{(t)}$) and
+($x_{n+1}$,$y_{n+1}^{(b)}$).
+The relations $x_n<x_{n+1}$ and $y_n^{(b)}\leq y_n^{(t)}$
+should hold. For the duration of the shading the optional edge effect field
+`\type{<$\epsilon_{l;i}$,$\epsilon_{r;i}$,$\epsilon_{d;i}$,$\epsilon_{u;i}$>}'
+overrides the specifications made by \verb+\setshadesymbol+. The second form
+should be used when \verb+\setquadratic+ is in effect.
+\item[\tt\bsl writesavefile \{\emph{message}\}]
+\begin{sloppypar}
+This command writes out the text \emph{message} on the file specified by the
+most recent \verb+\savelinesandcurves+ command.

+the current coordinate system to the origin.
+\item[\tt\bsl Ydistance\{\emph{ycoord}\}]
+This command is used to get the vertical distance from the point \emph{ycoord} in
+the current coordinate system to the origin.
+\end{syntax}
+
+\section{Parameters}
+The parameters which can be altered to change \PiCTeX's behaviour are:
+\begin{syntax}
+\item[\tt\bsl headingtoplotskip]
+This is the distance between the baseline of the heading and the top of the
+plot area, or the top of the top axis structure.
+\item[\tt\bsl linethickness]
+This parameter is the default thickness of axes, tick marks, and grid lines.
+This control sequence has its normal \LaTeX{} meaning outside of \PiCTeX{}
+pictures,
+but \verb+\pictexlinethickness+ can be used outside of \PiCTeX{}
+pictures to get the same effect as \PiCTeX's \verb+\linethickness+.
+\item[\tt\bsl longticklength]
+This is the default length of long ticks.
+\item[\tt\bsl plotsymbolspacing]
+This parameter defines the distance between plotted symbols in lines and
+curves.
+\item[\tt\bsl shortticklength]
+This is the default length of short ticks.
+\item[\tt\bsl stackleading]
+This is the default space put between items in a \type{stack}.
+\item[\tt\bsl tickstovaluesleading]
+This parameter defines the distance separating the ticks and the box enclosing
+the tick values.
+\item[\tt\bsl totalarclength]
+This register in general contains the length of the last line or curve.
+\item[\tt\bsl valuestolabelleading]
+This is the distance separating the box enclosing the tick values and the box
+enclosing the axis label.
+\end{syntax}
+
+\section{Miscellaneous}
+A couple of extra commands are provided by \PiCTeX{} for formatting names:
+\begin{syntax}
+\item[\tt\bsl PiC]
+This command produces `\PiC'.
+\item[\tt\bsl PiCTeX]
+This command produces `\PiCTeX'.
+\end{syntax}
