\section{Introduction}
This note describes a package of \LaTeX\ macros for printing
Z and Object-Z specifications.  The macros and this note are
based originally on Mike Spivey's \verb'zed.sty' macros and documentation.
The package does several related things for you:
\begin{itemize}
\item   It loads extra fonts and defines mnemonics
	for the Z symbols they contain.
\item   It defines macros for some Z symbols (e.g. $\pinj$) which
        don't appear in any of our fonts.
\item   It fixes the way \TeX\ sets letters in mathematical formulas so
        that multi-character identifiers look better.
\item   It provides various brands of `boxed mathematics'
        which appear in Z and Object-Z specifications.
\end{itemize}

The package is kept in a file {\tt oz.sty}
in the directory \verb|/usr/local/lib/tex/localinputs|.
This directory should be mentioned in your \verb|TEXINPUTS| shell variable.
To use the macros you just begin your \LaTeX\ document with something like:
\begin{quote}
\begin{verbatim}
\documentstyle[11pt,oz]{article}
\end{verbatim}
\end{quote}
\vspace*{-1.5ex}

\section{Schema Boxes}

The example below shows a schema on the left and what you
need to say to get it on the right.

\begin{example}
\begin{schema}{BirthdayBook}
    known: \pset NAME \\
    birthday: NAME \pfun DATE
\ST
    known = \dom birthday
\end{schema}
\verbpart
\begin{schema}{BirthdayBook}
    known: \pset NAME \\
    birthday: NAME \pfun DATE
\ST
    known = \dom birthday
\end{schema}
\end{verbatim}
\end{example}

The command \verb|\ST| (read `Such That') is the same as the previously used
command \verb|\where| which has been kept as an alias for upward compatibility.
If you want a schema with no name, just a horizontal rule at the top,
use the \verb|schema*| environment instead.
You can set various parameters (see Section 7) to change the box style,
for example:

\begin{example}
\begin{leftschemas}
\zedcornerheight=3ex\zedlinethickness=0.9pt
\zedbar=10em\zedleftsep=1.5em
\begin{schema}{BirthdayBook}
    known: \pset NAME \\
    birthday: NAME \pfun DATE
\ST
    known = \dom birthday
\end{schema}
\end{leftschemas}
\nextside\small\vspace{-1ex}
\begin{quote}
In document preamble: \hfil\\
~~\verb|\leftschemas|\hfil\\
~~\verb|\zedcornerheight=3ex|\hfil\\
~~\verb|\zedlinethickness=0.9pt|\hfil\\
~~\verb|\zedbar=10em\zedleftsep=3em|\hfil\\
\end{example}

Schemas can also be defined using a horizontal notation, for example:
\begin{example}
\begin{zed}
BirthdayBook \sdef \lsch \ldots \rsch
\end{zed}
\verbpart
$BirthdayBook \sdef \lsch ... \rsch$
\end{verbatim}
\end{example}

A generic schema is produced as follows.

\begin{example}
\begin{genschema}{Pool}{RESOURCE}
owner : RESOURCE \pfun USER \\
free : \pset RESOURCE
\ST
(\dom owner) \uni free = RESOURCE \\
(\dom owner) \int free = \emptyset
\end{genschema}
\verbpart
\begin{genschema}{Pool}{RESOURCE}
owner : RESOURCE \pfun USER \\
free : \pset RESOURCE
\ST
(\dom owner) \uni free = RESOURCE \\
(\dom owner) \int free = \emptyset
\end{genschema}
\end{verbatim}
\end{example}

\section{Axiomatic definitions}

A `liberal' axiomatic definition is produced as follows.

\vspace{-1ex}\begin{example}
\vspace{\ht\zstrutbox}
\begin{axdef}
limit : \nat
\ST
limit \leq 65536
\end{axdef}
\verbpart
\begin{axdef}
limit : \nat
\ST
limit \leq 65536
\end{axdef}
\end{verbatim}
\end{example}

A `generic' axiomatic definition is produced as follows.

\begin{example}
\begin{gendef}{X,Y}
first : X \prod Y \tfun X
\ST
\all x : X; y : Y \dot first(x,y) = x
\end{gendef}
\verbpart
\begin{gendef}{X,Y}
first : X \prod Y \tfun X
\ST
\all x : X; y : Y \dot first(x,y) = x
\end{gendef}
\end{verbatim}
\end{example}

A `unique' axiomatic definition is produced as follows.

\begin{example}
\begin{uniqdef}
\pi : \real
\ST
\pi = 3.14159265\ldots
\end{uniqdef}
\verbpart
\begin{uniqdef}
\pi : \real
\ST
\pi = 3.14159265\ldots
\end{uniqdef}
\end{verbatim}
\end{example}

\section{Object-Z Class Boxes}

Object-Z allows class types to be defined using a box very
similar to the schema box previously described.
It allows the previously described boxed environments
(as well as nested sub-classes) to be placed within a class box.
%
In addition, special names can be used for some of the boxed-environments
when they appear within a class box.
The following example illustrates a class definition.

\begin{example}
\begin{class}{Shape}
\also
colour : Colour \\
\begin{axdef}
perim : \real
\ST
perim > 0
\end{axdef} \\
\begin{classcom}
This class has 2 constants
$colour$ and $perim$.
\end{classcom} \\
\begin{state}
x, y : \real
\end{state} \\
\begin{init}
x = y = 0
\end{init} \\
\begin{op}{Translate}
\Delta (x,y) \\
dx?, dy? : \real
\ST
x' = x + dx? \\
y' = y + dy?
\end{op}
\end{class}
\verbpart
\begin{class}{Shape}
\also
colour : Colour \\
\begin{axdef}
perim : \real
\ST
perim > 0
\end{axdef} \\
\begin{classcom}
This class has 2 constants
$colour$ and $perim$.
\end{classcom} \\
\begin{state}
x, y : \real
\end{state} \\
\begin{init}
x = y = 0
\end{init} \\
\begin{op}{Translate}
\Delta (x,y) \\
dx?, dy? : \real
\ST
x' = x + dx? \\
y' = y + dy?
\end{op}
\end{class}
\end{verbatim}
\end{example}

The \verb|classcom| environment hasn't been seen before.
It creates a paragraph of text with the same margins as used
for schemas and other Z environments.  It uses a special font
intended for use when placing comments inside classes.
A similar environment, \verb|zpar|, uses the same margins
but with the normal roman font.

The \verb|\begin{init}| command is an abbreviation for
\verb|\begin{schema}{\Init}|.  Similarly \verb|\begin{state}|
is a more meaningful synonym for \verb|\begin{schema*}|.

You will be given \LaTeX\ warning messages if you try to
use a \verb|state| environment outside of a class box
or if you try to place an environment such as \verb|syntax|
inside a class.  You can ask for additional help in these
cases using the normal \LaTeX\ \verb|h| or \verb|H| help commands.
If you proceed with \LaTeX ing, the macros will attempt to
do the best they can to do what you probably intend, even though
you are violating the recommended nesting guidelines.

\section{Controlling the Spacing within Equations and Boxes}

Most of the special Z symbols are defined
in a way that allows \TeX\ to space them out correctly.
Sometimes, however, you'll need to give \TeX\ a helping hand if
you want it to get the spacing right.  For example, to get $map\,f$
you need to type \verb|map\,f|.  The \verb|\,| gives you a thin space:
if this is omitted, the input \verb|map f| gives
$map f$, because \TeX\ ignores spaces in math mode.

Sometimes it is useful to indent the left margin to emphasis
the logical structure of the predicate.
The command \verb|\t1| does this by making the corresponding
line in the output have one helping of indentation.
As things get more nested, you can say \verb|\t2|, \verb|\t3|, and so on.
But if you should ever get beyond \verb|t9|, you'll need to use braces
around the argument: \verb|\t{10}|, and you'd better look for some way
to simplify your specification!
These little tab marks might look different to normal tabs
but are never the less convenient. They're short,
and they don't get longer as the tabbing gets deeper, within reason,
so they can be tucked in neatly on the left, well away from the maths.
The size of `helping' you get with \verb|\t| is determined by
the \verb|\zedtab| parameter (see Section 7).

If you want a more powerful aligning mechanism than tabbing
then you can use the margin stack as shown in the example below.
The command \verb|\M| sets the future left margin to the current
horizontal position and pushes the old value onto a margin stack.
The command \verb|\O| resets the left margin to its previous value
(which is popped off the stack).

\begin{example}
\begin{schema}{Test}
x, y : \nat
\ST
x + 1/x = 0 \imp \M y + 1/y = 0 \\
y = x \O \\
\end{schema}
\verbpart
\begin{schema}{Test}
x, y : \nat
\ST
x + 1/x = 0 \imp \M y + 1/y = 0 \\
y = x \O \\
\end{schema}
\end{verbatim}
\end{example}

If a schema or other box contains more than one predicate below the
line, it often looks better to add a tiny vertical space between
them, as in this example:

\begin{example}
\begin{schema}{AddBirthday}
  \Delta BirthdayBook \\
  n?: NAME \\
  d?: DATE
\ST
  n? \nem known
\also
  birthday' = birthday \uni \{n? \map d?\}
\end{schema}
\verbpart
\begin{schema}{AddBirthday}
  \Delta BirthdayBook \\
  n?: NAME \\
  d?: DATE
\ST
  n? \nem known
\also
  birthday'=birthday \uni \{n? \map d?\}
\end{schema}
\end{verbatim}
\end{example}

This is done with the command \verb|\also|, which behaves syntactically
like \verb|\ST|.
The command \verb|\also| is provided {\em instead\/} of the
optional argument to \verb|\\|
which \LaTeX\ provides in other environments.
If larger vertical spacing is required, the commands
\verb|\Also| and \verb|\ALSO| may be used (giving 2 and 4 times
as much space as \verb|\also| respectively).

Normally, the contents of a schema box are kept on a single page.
For large schemas it may be necessary to split the box across pages.
You must specify which places are suitable for splitting using one of
\verb|\zbreak|, \verb|\Zbreak| or \verb|\ZBREAK|.  If no split is
performed at this point, a vertical space will be added as if the
user had typed \verb|\also|, \verb|\Also|, or \verb|\ALSO| respectively.
You can also use the \verb|\znewpage| command to force a page break within
a box.  (These breaking facilities will hopefully never be needed for schemas,
but may become necessary for class specifications.)

\section{Other Display Environments}

The \verb|zed| environment can be used to set multi-line formulas without
an enclosing box: it is useful for given-set declarations, theorems, and the
miscellaneous bits of mathematics that don't come in a box:

\vspace{-1ex}\begin{example}
\vspace{\ht\zstrutbox}
\begin{zed}
    \all n: \nat \dot \\
\t1         n+n \mem even.
\end{zed}
\verbpart
\begin{zed}
    \all n: \nat \dot \\
\t1         n+n \mem even.
\end{zed}
\end{verbatim}
\end{example}

The formula \verb|\begin{zed} ... \end{zed}| may be abbreviated to
\verb|\[ ... \]|; the \verb|zed| environment is a generalization of the
\verb|displaymath| environment of \LaTeX, so this redefinition of
commands is fairly benign. Notice that the maths is set flush left on the
same indentation as schemas and their friends.
Here too you can use \verb|\also| for a little extra space
between lines.

For algebraic-style proofs, there is the \verb|argue| environment.
This is like the \verb|zed| environment, but the separation between
lines is increased a little, and page breaks may occur between lines.
When the left-hand side is long this style wastes less space
than the \LaTeX\ \verb|eqnarray| style.
The intended use is for arguments like this:
\begin{argue}
    rev(append(cons(x,s),t)) \\
\t1     = rev(cons(x,append(s,t))) \\
\t1     = append(rev(append(s,t)),cons(x,nil)) \\
\t1     = append(append(rev(t),rev(s)),cons(x,nil))
                \quad \hbox{by hypothesis} \\
\t1     = append(rev(t),append(rev(s),cons(x,nil))) \\
\t1     = append(rev(t),rev(cons(x,s))).
\end{argue}
Here is the input:
\begin{quote}
\begin{verbatim}
\begin{argue}
    rev(append(cons(x,s),t)) \\
\t1     = rev(cons(x,append(s,t))) \\
\t1     = append(rev(append(s,t)),cons(x,nil)) \\
\t1     = append(append(rev(t),rev(s)),cons(x,nil))
                \quad \hbox{by hypothesis} \\
\t1     = append(rev(t),append(rev(s),cons(x,nil))) \\
\t1     = append(rev(t),rev(cons(x,s))).
\end{argue}
\end{verbatim}
\end{quote}

The example below shows an inference rule (the optional argument
to \verb|\derive| gives a side-condition of the rule):

\vspace{-1ex}\begin{example}
\vspace{\ht\zstrutbox}
\begin{infrule}
    \Gamma \shows P
\derive[x \nem freevars(\Gamma)]
    \Gamma \shows \all x \dot P
\end{infrule}
\verbpart
\begin{infrule}
    \Gamma \shows P
\derive[x \nem freevars(\Gamma)]
    \Gamma \shows \all x \dot P
\end{infrule}
\end{verbatim}
\end{example}

The \verb|syntax| environment is used for making displays like this:

\begin{syntax}
  EXPR & \ddef & IDENT      & identifier \\
       & \bbar & EXPR\;EXPR & application \\
       & \bbar & \lambda IDENT \dot EXPR & lambda-abstraction.
\end{syntax}
from input like this:
\begin{quote}
\begin{verbatim}
\begin{syntax}
  EXPR & \ddef & IDENT                   & identifier \\
       & \bbar & EXPR\;EXPR              & application \\
       & \bbar & \lambda IDENT \dot EXPR & lambda-abstraction.
\end{syntax}
\end{verbatim}
\end{quote}

This kind of thing is useful when you're describing a language,
and it can also be used for data-type definitions as shown below.
The optional final column was omitted below by leaving out the third \verb|&|.

{\small
\vspace{-1ex}\begin{example}
\vspace{0.5\ht\zstrutbox}
\begin{syntax}
TYPE & \ddef & givenT  \lang NAME \rang \\
     & \bbar & powerT  \lang TYPE \rang \\
     & \bbar & tupleT  \lang \seq TYPE \rang \\
     & \bbar & schemaT \lang IDENT \ffun TYPE \rang \\
     & \bbar & classT  \lang IDENT \ffun ClassAttr \rang \\
\end{syntax}
\verbpart
\begin{syntax}
TYPE & \ddef & givenT  \lang NAME \rang \\
& \bbar & powerT \lang TYPE \rang \\
& \bbar & tupleT \lang \seq TYPE \rang \\
& \bbar & schemaT \lang IDENT \ffun TYPE \rang \\
& \bbar & classT \lang IDENT \ffun ClassAttr \rang
\end{syntax}
\end{verbatim}
\end{example}}

This can be compared with the layout adopted by the UQ Z editor (version 1).

{\small
\vspace{-1ex}\begin{example}
\vspace{0.5\ht\zstrutbox}
\begin{zed}
TYPE \ddef \M givenT  \lang NAME \rang \\
     \bbar powerT  \lang TYPE \rang \\
     \bbar tupleT  \lang \seq TYPE \rang \\
     \bbar schemaT \lang IDENT \ffun TYPE \rang \\
  \bbar classT  \lang IDENT \ffun ClassAttr \rang \O
\end{zed}
\verbpart
\begin{zed}
TYPE \ddef \M givenT  \lang NAME \rang \\
\bbar powerT \lang TYPE \rang \\
\bbar tupleT \lang \seq TYPE \rang \\
\bbar schemaT \lang IDENT \ffun TYPE \rang \\
\bbar classT \lang IDENT \ffun ClassAttr \rang \O
\end{zed}
\end{verbatim}
\end{example}}

The {\tt sidebyside} environment allows a display as shown in the
first two columns below to be produced from the text of the third column.
Note the use of the \verb|\comment| command.

\begin{example}
\begin{sidebyside}
\begin{schema}{Schema}
\comment*{declarations}
\ST
a < b & [{\sf pred-1}]\\
aaaaa < bbbbb \comment{pred-2}
\end{schema}
\nextside
\begin{zpar}
This is a paragraph which has the same
margins as the standard schemas do.
\end{zpar}
\end{sidebyside}
\verbpart
\begin{sidebyside}
\begin{schema}{Schema}
\comment*{declarations}
\ST
a < b \comment{pred-1} \\
aaaaa < bbbbb \comment{pred-2}
\end{schema}
\nextside
\begin{zpar}
This is a paragraph which has the same
margins as the standard schemas do.
\end{zpar}
\end{sidebyside}
\end{verbatim}
\end{example}

In fact, this environment was used throughout this note to
display the examples beside the required input text.
Incidentally, the above example shows that \verb|sidebyside|
environments can be nested; so what the author of this note typed
to get the above display was:

\begin{quote}
\begin{verbatim}
\begin{sidebyside}
        \begin{sidebyside}
                ...
        \nextside
                ...
        \end{sidebyside}
\nextside
        ...
\end{sidebyside}
\end{verbatim}
\end{quote}

This resulted in the first two columns being equally spaced and
together taking up as much space as the third column.
You can have more than 2 columns without nesting by specifying an optional
parameter to \verb|sidebyside|.  For example, the display below has three
equally spaced columns obtained using \verb|\begin{sidebyside}[3]|.
\begin{sidebyside}[3]
\begin{schema}{BirthdayBook}
    known: \pset NAME \\
    birthday: NAME \pfun DATE
\ST
    known = \dom birthday
\end{schema}
\nextside
\begin{schema}{BirthdayBook}
    known: \pset NAME \\
    birthday: NAME \pfun DATE
\ST
    known = \dom birthday
\end{schema}
\nextside
\begin{zpar}
Don't get carried away with \verb|sidebyside|
like this example does.
\end{zpar}
\end{sidebyside}

\section{Style Parameters}

\begin{description}
\item[\tt\string\zedindent] The (horizontal) indentation for mathematical text.
	By default, this is the same as \verb|\leftmargini|, the indentation
	used for list environments.
\item[\tt\string\zedleftsep] The (horizontal) space between the vertical line on the left
	of schemas, etc., and the maths inside. The default is 1em.
\item[\tt\string\zedtab] The unit of indentation used by \verb|\t|. The default
	is 2em.
\item[\tt\string\zedbar] The length of the horizontal bar in the middle of a
	schema. The default is 8em.
\item[\tt\string\leftschemas] A declaration which makes schema names be
	set flush left. Use it in the document preamble.
\item[\tt\string\zedlinethickness] The thickness of the lines that make up
	schema and class boxes.  You can change the thickness
	with a command such as \verb|\zedlinethickness=0.1pt|.  This may
	be useful if you are creating overhead slides.
	\begin{description}
	\makeatletter
	\item[0.1pt] \zedlinethickness=0.1pt
		~\hbox to 4cm{\z@hrulefill}
	\item[0.4pt] \zedlinethickness=0.4pt
		~\hbox to 4cm{\z@hrulefill}~~~(The default)
	\item[\hphantom{0.}1pt] \zedlinethickness=1pt
		~\hbox to 4cm{\z@hrulefill}
	\end{description}
\item[\tt\string\baselinestretch] The spacing for the text part of your
	document.  It doesn't change the spacing within Z environments.  It's
	default value is 1.  A command such as \verb|\def\baselinestretch{2}|
	will make your text double spaced, but not your Z environments.
\item[\tt\string\zedbaselinestretch] The spacing for the Z environment
	part of your document.  It's default value is 1.
\item[\tt\string\zedsize] The size of the material within the Z
	part of your document. It doesn't affect the remainder of your document.
	For example, \verb|\zedsize{\large}| will give you large Z symbols
	and equations but will not affect the size of the surrounding text.
\item[\tt\string\zedcornerheight] The height of `corners' that can be placed
	on the right hand side of the top and bottom lines of schema and class
	boxes.  The default is 0em (i.e. no corners).
\end{description}

\section{Symbols}

Multi-letter identifiers have been changed to look
better than they do with vanilla \LaTeX: instead of
$\mit specifications$, you get $specifications$.
The letters haven't been spread apart, and the
ligature $fi$ has been used.

Almost all of the mathematical symbols of \LaTeX\ can be used;
some have been redefined---usually to fix the spacing so that it is
suitable for Z specifications.
The commands for obtaining additional symbols are listed below.
Sometimes more than one command may produce a symbol you
require.  You should use the one that seems to be designed for the
context you have in mind.  This is because the spacing around (and size of)
symbols has been chosen for their typical context.

Throughout the lifetime of these macros a number of alternate control
sequences for any symbol may have existed.  A list of aliases has been
set up so that old commands may still be used.  It is
recommended however that you stick to the recommended command
names for symbols as these names may be supported by other tools.
Within the table below non-recommended aliases are surrounded by
brackets, e.g., \verb|(\power)|.

\subsection{Variable-sized Symbols}
These symbols come in two sizes which
do not vary with the point size of your
font.  The big size can be obtained
by preceding the symbol command with
the command \verb'\displaystyle'.
\begin{symbols}[1.3]
\sum \displaystyle \sum & \verb'\sum' \\
\product \displaystyle \product & \verb'\product' \\
\coprod \displaystyle \coprod & \verb'\coprod' \\
\integral \displaystyle \integral & \verb'\integral' \\

\biguplus \displaystyle \biguplus & \verb'\biguplus' \\
\end{symbols}

\subsection{Delimiters}
\vspace*{-1ex}
These symbols can be made large to surround large formula.
E.g., $$\left\lfloor\displaystyle\sum_{i=1}^n x^i\right\rfloor$$
was generated using

\begin{verbatim}
\left\lfloor...\right\rfloor
\end{verbatim}
