\section{Introduction}
This paper is described how to use the {\sf jcmlatex.cls} class file
for publication in the {\it Journal of Computational Mathematics}.
The {\sf jcmlatex.cls} class file preserves much of the standard
\LaTeXe \ interface so that authors can easily convert their
standard \LaTeXe \ {\sf article} style files to the {\sf jcmlatex}
style.

\section{Preparation of Manuscript}
The Title Page should contain the article title, authors' names and complete affiliations, footnotes to the title,
and the postal address for manuscript correspondence (including e-mail address and fax numbers).
The Abstract should provide a brief summary of the main findings of the paper.

\medskip

References should be cited in the text by a number in square brackets. Literature cited should appear on a
separate page at the end of the article and should be styled and punctuated using standard abbreviations for
journals (see Chemical Abstracts Service Source Index, 1989). For unpublished lectures of symposia,
include title of paper, name of sponsoring society in full, and date.
Give titles of unpublished reports with ``(unpublished)" following the reference.
Only articles that have been published or are in press should be included in the references.
Unpublished results or personal communications should be cited as such in the text.
Please note the sample at the end of this paper.

\medskip

Equations should be typewritten whenever possible and the number placed in parentheses at the right margin.
Reference to equations should use the form ``Eq. (1.1)" or simply ``(1.1)."
Superscripts and subscripts should be typed or handwritten clearly above and below the line, respectively.

\medskip

Figures should be in a finished form suitable for publication. Number figures consecutively with Arabic numerals.
Lettering on drawings should be of professional quality or generated by high-resolution computer graphics and
must be large enough to withstand appropriate reduction for publication.

\section{Header Information}
The heading for any file using {\sf jcmlatex.cls} is like this;

\section{Some Remarks}
\subsection{Mathematics}
{\sf jcmlatex.cls} makes the full functionality of \AmS\TeX \ available. We encourage
the use of the {\sf align}, {\sf gather} and {\sf multline} environments for displayed
mathematics.

\subsection{Cross-referencing}
The use of the \LaTeXe cross-reference system for figures, tables, equations
and citations is encouraged.
