[comp.text.tex] Equation numbering in LaTeX

link@stew.ssl.berkeley.edu (Richard Link) (11/07/90)

I need to number equations in an appendix as (A1), (A2), etc.,
where the () are right-justified in the usual manner.

Help will be sincerely appreciated.

%%%%%%%%%%%%%%%%%%% letteredEquations.sty %%%%%%%%%%%%%%%%%%%%%%%%
\newcommand{\AlphNum}[2]{\prtAlphNum{\@nameuse{c@#1}}#2}

\newcommand{\prtAlphNum}[2]{(#2\number #1)}

\newcounter{eqnSaver}

\def\eqNum#1#2{\setcounter{eqnSaver}{\value{equation}}%
\setcounter{equation}{#2}%
\renewcommand{\theequation}{\AlphNum{equation}#1}}

\def\eqNormal{\setcounter{equation}{\value{eqnSaver}}%
\renewcommand{\theequation}{\arabic{equation}}}
%%%%%%%%%%%%%%%%%%% End Hack %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

Use as follows:

\eqNum{A}{0}% Switch to (Ai) starting with 0

... some equations ...

\eqNorm % Back to normal

Greetings,
   I have a problem with a math paper I wrote in LaTeX and submitted
to a conference proceedings recently. Briefly, in my original version
the equations were numbered consecutively (1), (2), ... throughout the
document. The publishers have changed the document style from 'article'
to a style of their own ('plainbook', although the style file they have
sent me begins with a comment line '% book.sty 17-Dec-85), and in the
process have changed the equation numbers to (0.1), (0.2), ... Neither
they nor I want the numbering in this format, but neither they nor I
know how to fix it. (Personally, I think that they messed it up so they
should fix it, but they disagree.) Can anyone tell me how to force
equations to number consecutively throughout the document (or explain
how anyone gets them to number any other way - according to the LaTeX
manual the way I want should be the natural one).

  Please reply by e-mail as I do not usually read this group.

  Thanks,
  Kevin.

BTW, all equations to be numbered are in \begin{equation} or
\begin{eqnarray} formats.
