The Body

The commands that you should be most familiar with to typeset the body of your paper are the sectioning commands. They are
section:
Same level as the Introduction.
subsection:
Secondary headings, such as ``Objectives.''
subsubsection:
Third level headings.
paragraph:
Avoid fourth level headings.
The usage of these commands can be best described by an example:
\subsection{The Body}
This is the sectioning command for the section you are now reading.

You may want to avoid fourth level headings because it requires an additional font for your TEX installation: cmcscsl10. This is a slanted, small caps font. If you have METAFONT working on your system, this is not a problem. Source code for this font is available with the style files. Ask you local TEX guru for help, should you need it.
