+% \section{Introduction}
+%
+% This file provides macros to typeset Object Z schemas.
+%\subsection{Modification History}
+%
+% The original zed.sty file was written by Mike Spivey.
+% These macros have been extensively modified to
+% include extra symbols and environments for Object-Z
+% and now have little resemblence to the original macros.
+% Mike Spivey has also extended his macros along
+% different lines for Z --- the latest version of macros
+% are called fuzz.sty and come with a syntax checker for Z.
+% They can be purchased for a small fee from:
+% \texttt{mike@prg.oxford.ac.uk}

+%
+%\subsection{Known Problems}
+%
+%\begin{enumerate}
+% \item |\bBigg| defines |\zBig|, etc as fixed font sizes -
+% in the original oz.sty (for \LaTeX 2.09) these sizing commands change
+% the font size relative to the current font size (so a |\zBig|
+% in the scope of a |\large| is bigger than a |\zBig|
+% in the scope of a |\normalsize|);
+% \item |sidebyside| works very poorly with the |class| environment
+% - indentation of operation schemas is wrong;
+% \item the |calc| package is needed for |\zedbaselinestretch|.
+%\end{enumerate}
+%
+%
+%\subsection{The Object-Z Homepage}
+%
+% The Object-Z homepage (http://svrc.it.uq.edu.au/Object-Z/) contains:
+%
+% \begin{itemize}
+% \item Papers and Tech-reports on Object-Z;
+% \item {\bf wizard} - the Object-Z type checker.
+% \end{itemize}
+%
+% \noindent Please post any updates that you may make to this file to the
+% Formal Methods Group -- fmg@it.uq.edu.au

+%
+% The AMS extra symbol fonts are loaded if we are not using Lucida New Math.
+% Note: msam and msbm sometimes called euxm and euym respectively
+% NOTE: the new AMSFONTS 2.0 call these fonts msam and msbm repectively
+% (the fonts below need to be renamed if you want to use the new fonts)

+% Allow change of size within schemas. This is a sod to get right;
+% my principle (eventually!) was to go out of math temporarily, change
+% size, go into an inner math, do the business, then get out of math
+% and back to outer math.

+%
+%\section{Z symbols}
+%
+% The mathcodes for the letters A, ..., Z, a, ..., z are changed to
+% generate text italic rather than math italic by default. This makes
+% multi-letter identifiers look better. The mathcode for character c
+% is set to |"7000| (variable family) + |"400| (text italic) + |c|.
+%
+% \begin{macrocode}
+\def\@setmcodes#1#2#3{{\count0=#1 \count1=#3
+ \loop \global\mathcode\count0=\count1 \ifnum \count0<#2
+ \advance\count0 by1 \advance\count1 by1 \repeat}}
+% \end{macrocode}
+% Use |\hexnumber@\symitalics|
+% in case other families are loaded before.
+% (from D. Roegel, July 13, 1994)
+% \begin{macrocode}
+\@setmcodes{`A}{`Z}{"7\hexnumber@\symitalics41}
+\@setmcodes{`a}{`z}{"7\hexnumber@\symitalics61}
+% \end{macrocode}
+%
+% Also, the mathcode for semicolon is set to |"8000|, so it behaves as an
+% active character in math mode; it is defined to insert a thick space.
+% |\semicolon| is a semicolon as an ordinary symbol.
+%
+% \begin{macrocode}
+\let\@mc=\mathchardef
+\mathcode`\;="8000 % Makes ; active in math mode
+{\catcode`\;=\active \gdef;{\semicolon\;}}
+\@mc\semicolon="603B
+% \end{macrocode}

+% |\z@op |& makes a large math operator\\
+% |\z@rel|& makes a math relation\\
+% |\z@bin|& makes a binary operator\\
+%\end{tabular}

+% Each use a mathstrut to defeat TeX's vertical adjustment.
+% |\z@bigXXX| is a big version of symbol
+%

+%\subsection{Utility macros for Z environments}
+%
+% Here are environments for the various sorts of displays which occur in
+% Z documents. All displays are set flush left, indented by |\zedindent|,
+% by default |\leftmargini|. Schemas, etc, are made just wide enough to
+% give equal margins left and right.
+%
+% Some environments (schema, etc.) must only be split at |\zbreak|,
+% and others (e.g. argue) may be split arbitrarily. All generate
+% alignment displays, and penalties are used to control page breaks.

+UPDATE NOVEMBER 1996
+********************
+
+The Formal Methods Group in the Computer Science Department at the
+University of Queensland recently released 'wizard', a type checker
+for Object-Z specifications. Included in the wizard release was an
+updated version of the oz.sty file for LaTeX 2.09.
+
+I have implemented all changes made in the oz.sty for LaTeX 2.09,
+since it's last official release in late 1990, into the oz.dtx file
+which you maintain for LaTeX 2e. I have attached my updated version
+of oz.dtx to this message so that you may check these modifications
+and officially release the updated version.
+
+The changes were made to the oz.dtx file with last changes logged
+on 22 Feb 95 (this is the version currently available from CTAN).
+All modifications and additions I have made are clearly indicated in
+the updated file for your convenience.
+
+Should you need to compare my changes with the updated oz.sty file for
+LaTeX 2.09, you can download the wizard archive from the following url:
+
+ ftp://ftp.cs.uq.edu.au/pub/SVRC/software/wizard.tar.gz
+
+The new oz.sty file and oz.tex file are located in the wizard/tex
+subdirectory when the archive is extracted.
+
+Please contact me if you need to.
+
+Thanks.
+
+Dave.
