The LaTeX command typesets a file of text using the TeX program and the
LaTeX Macro package for TeX. To be more specific, it processes an input
file containing the text of a document with interspersed commands that
describe how the text should be formatted. It produces at least three
files as output:
</P>
<OL>
<LI>
A "Device Independent", or <TT>`.dvi'</TT> file. This contains commands that
can be translated into commands for a variety of output devices. You
can view the output of LaTeX by using a program such as <CODE>xdvi</CODE>,
which actually uses the <TT>`.dvi'</TT> file.
<LI>
A "transcript" or <TT>`.log'</TT> file that contains summary information and
diagnostic messages for any errors discovered in the input file.
<LI>
An "auxiliary" or <TT>`.aux'</TT> file. This is used by LaTeX itself, for
things such as sectioning.
</OL>
<P>
For a description of what goes on inside TeX, you should consult
<CITE>The TeXbook</CITE> by Donald E. Knuth, ISBN 0-201-13448-9, published
jointly by the American Mathematical Society and Addison-Wesley
Publishing Company.

<H1><A NAME="SEC2" HREF="latex2e_toc.html#TOC2">Commands</A></H1>
<P>
A LaTeX command begins with the command name, which consists of a
<CODE>\</CODE> followed by either (a) a string of letters or (b) a single
non-letter. Arguments contained in square brackets, <CODE>[]</CODE>, are
optional while arguments contained in braces, <CODE>{}</CODE>, are required.
</P>
<P>
NOTE: LaTeX is case sensitive. Enter all commands in lower case
unless explicitly directed to do otherwise.
</P>
<H2><A NAME="SEC3" HREF="latex2e_toc.html#TOC3">Counters</A></H2>
<P>
<A NAME="IDX3"></A>
<A NAME="IDX4"></A>
</P>
<P>
Everything LaTeX numbers for you has a counter associated with it. The
name of the counter is the same as the name of the environment or
command that produces the number, except with no <CODE>\</CODE>. (enumi -
enumiv are used for the nested enumerate environment.) Below is a list
of the counters used in LaTeX's standard document classes to control
numbering.
</P>
<PRE>
part paragraph figure enumi
chapter subparagraph table enumii

</PRE>
<H3><A NAME="SEC4" HREF="latex2e_toc.html#TOC4">\addtocounter</A></H3>
<P>
<A NAME="IDX5"></A>
</P>
<P>
<CODE>\addtocounter{counter}{value}</CODE>
</P>
<P>
The <CODE>\addtocounter</CODE> command increments the <CODE>counter</CODE> by the
amount specified by the <CODE>value</CODE> argument. The <CODE>value</CODE>
argument can be negative.
</P>
<H3><A NAME="SEC5" HREF="latex2e_toc.html#TOC5">\alph</A></H3>
<P>
<A NAME="IDX6"></A>
<A NAME="IDX7"></A>
</P>
<P>
<CODE>\alph{counter}</CODE>
</P>
<P>
This command causes the value of the <CODE>counter</CODE> to be printed in
alphabetic characters. The <CODE>\alph</CODE> command uses lower case
alphabetic alphabetic characters, i.e., <CODE>a, b, c...</CODE> while the
<CODE>\Alph</CODE> command uses upper case alphabetic characters, i.e.,
<CODE>A, B, C...</CODE>.
</P>
<H3><A NAME="SEC6" HREF="latex2e_toc.html#TOC6">\arabic</A></H3>
<P>
<A NAME="IDX8"></A>
</P>
<P>
<CODE>\arabic{counter}</CODE>
</P>
<P>
The <CODE>\arabic</CODE> command causes the value of the <CODE>counter</CODE> to be
printed in Arabic numbers, i.e., <CODE>3</CODE>.
</P>
<H3><A NAME="SEC7" HREF="latex2e_toc.html#TOC7">\fnsymbol</A></H3>
<P>
<A NAME="IDX9"></A>
</P>
<P>
<CODE>\fnsymbol{counter}</CODE>
</P>
<P>
The <CODE>\fnsymbol</CODE> command causes the value of the <CODE>counter</CODE> to
be printed in a specific sequence of nine symbols that can be used for
numbering footnotes.
</P>
<P>
eg. From 1-9:
</P>
<P>
NB. <CODE>counter</CODE> must have a value between 1 and 9 inclusive.

<H3><A NAME="SEC8" HREF="latex2e_toc.html#TOC8">\newcounter</A></H3>
<P>
<A NAME="IDX10"></A>
<A NAME="IDX11"></A>
</P>
<P>
<CODE>\newcounter{foo}[counter]</CODE>
</P>
<P>
The <CODE>\newcounter</CODE> command defines a new counter named <CODE>foo</CODE>.
The counter is initialized to zero.
</P>
<P>
The optional argument <CODE>[counter]</CODE> causes the counter <CODE>foo</CODE> to
be reset whenever the counter named in the optional argument is
incremented.
</P>
<H3><A NAME="SEC9" HREF="latex2e_toc.html#TOC9">\refstepcounter</A></H3>
<P>
<A NAME="IDX12"></A>
</P>
<P>
<CODE>\refstepcounter{counter}</CODE>
</P>
<P>
The <CODE>\refstepcounter</CODE> command works like <CODE>\stepcounter</CODE>
See section <A HREF="latex2e.html#SEC11">\stepcounter</A>, except it also defines the current <CODE>\ref</CODE>
value to be the result of <CODE>\thecounter</CODE>.
</P>
<H3><A NAME="SEC10" HREF="latex2e_toc.html#TOC10">\roman</A></H3>
<P>
<A NAME="IDX13"></A>
<A NAME="IDX14"></A>
</P>
<P>
<CODE>\roman{counter}</CODE>
</P>
<P>
This command causes the value of the <CODE>counter</CODE> to be printed in
Roman numerals. The <CODE>\roman</CODE> command uses lower case Roman
numerals, i.e., <CODE>i, ii, iii...</CODE>, while the <CODE>\Roman</CODE> command
uses upper case Roman numerals, i.e., <CODE>I, II, III...</CODE>.
</P>
<H3><A NAME="SEC11" HREF="latex2e_toc.html#TOC11">\stepcounter</A></H3>
<P>
<A NAME="IDX15"></A>
</P>
<P>
<CODE>\stepcounter{counter}</CODE>
</P>
<P>
The <CODE>\stepcounter</CODE> command adds one to the <CODE>counter</CODE> and
resets all subsidiary counters.
</P>
<H3><A NAME="SEC12" HREF="latex2e_toc.html#TOC12">\setcounter</A></H3>
<P>
<A NAME="IDX16"></A>
<A NAME="IDX17"></A>
</P>
<P>
<CODE>\setcounter{counter}{value}</CODE>
</P>
<P>
The <CODE>\setcounter</CODE> command sets the value of the <CODE>counter</CODE> to
that specified by the <CODE>value</CODE> argument.
</P>
<H3><A NAME="SEC13" HREF="latex2e_toc.html#TOC13">\usecounter</A></H3>
<P>
<A NAME="IDX18"></A>
</P>
<P>
<CODE>\usecounter{counter}</CODE>
</P>
<P>
The <CODE>\usecounter</CODE> command is used in the second argument of the
<CODE>list</CODE> environment to allow the counter specified to be used to
number the list items.
</P>
<H3><A NAME="SEC14" HREF="latex2e_toc.html#TOC14">\value</A></H3>
<P>
<A NAME="IDX19"></A>
<A NAME="IDX20"></A>
</P>
<P>
<CODE>\value{counter}</CODE>
</P>
<P>
The <CODE>\value</CODE> command produces the value of the <CODE>counter</CODE> named
in the mandatory argument. It can be used where LaTeX expects an
integer or number, such as the second argument of a <CODE>\setcounter</CODE>
or <CODE>\addtocounter</CODE> command, or in:
</P>
<PRE>
\hspace{\value{foo}\parindent}
</PRE>
<P>
It is useful for doing arithmetic with counters.

<H2><A NAME="SEC15" HREF="latex2e_toc.html#TOC15">Cross References</A></H2>
<P>
<A NAME="IDX21"></A>
</P>
<P>
One reason for numbering things like figures and equations is to refer
the reader to them, as in "See Figure 3 for more details."
</P>
<H3><A NAME="SEC16" HREF="latex2e_toc.html#TOC16">\label</A></H3>
<P>
<A NAME="IDX22"></A>
</P>
<P>
<CODE>\label{key}</CODE>
</P>
<P>
A <CODE>\label</CODE> command appearing in ordinary text assigns to the
<CODE>key</CODE> the number of the current sectional unit; one appearing
inside a numbered environment assigns that number to the <CODE>key</CODE>.
</P>
<P>
A <CODE>key</CODE> can consist of any sequence of letters, digits, or
punctuation characters. Upper and lowercase letters are different.
</P>
<P>
To avoid accidentally creating two labels with the same name, it is
common to use labels consisting of a prefix and a suffix separated by a
colon. The prefixes conventionally used are
</P>
<UL>
<LI>
<CODE>cha</CODE>
for chapters
<LI>
<CODE>sec</CODE>
for lower-level sectioning commands
<LI>
<CODE>fig</CODE>
for figures
<LI>
<CODE>tab</CODE>
for tables
<LI>
<CODE>eq</CODE>
for equations
</UL>
<P>
Thus, a label for a figure would look like <CODE>fig:bandersnatch</CODE>.
</P>
<H3><A NAME="SEC17" HREF="latex2e_toc.html#TOC17">\pageref</A></H3>
<P>
<A NAME="IDX23"></A>
<A NAME="IDX24"></A>

</PRE>
<P>
Math arrays are produced with the array environment. It has a single
mandatory argument describing the number of columns and the alignment
within them. Each column, <CODE>coln</CODE>, is specified by a single letter
that tells how items in that row should be formatted.
</P>
<UL>
<LI>
<CODE>c</CODE> -- for centred
<LI>
<CODE>l</CODE> -- for flush left
<LI>
<CODE>r</CODE> -- for flush right
</UL>
<P>
Column entries must be separated by an <CODE>&</CODE>. Column entries may
include other LaTeX commands. Each row of the array must be terminated
with the string <CODE>\\</CODE>.
</P>
<P>
Note that the <CODE>array</CODE> environment can only be used in math mode, so
normally it is used inside an <CODE>equation</CODE> environment.

The <CODE>center</CODE> environment allows you to create a paragraph consisting of
lines that are centred within the left and right margins on the current
page. Each line must be terminated with the string <CODE>\\</CODE>.

</P>
<P>
This declaration corresponds to the <CODE>center</CODE> environment. This
declaration can be used inside an environment such as <CODE>quote</CODE> or in
a <CODE>parbox</CODE>. The text of a figure or table can be centred on the
page by putting a <CODE>\centering</CODE> command at the beginning of the
figure or table environment.
</P>
<P>
Unlike the <CODE>center</CODE> environment, the <CODE>\centering</CODE> command does
not start a new paragraph; it simply changes how LaTeX formats paragraph
units. To affect a paragraph unit's format, the scope of the
declaration must contain the blank line or <CODE>\end</CODE> command (of an
environment like quote) that ends the paragraph unit.

The <CODE>enumerate</CODE> environment produces a numbered list. Enumerations
can be nested within one another, up to four levels deep. They can also
be nested within other paragraph-making environments.
</P>
<P>
Each item of an enumerated list begins with an <CODE>\item</CODE> command.
There must be at least one <CODE>\item</CODE> command within the environment.
</P>
<P>
The <CODE>enumerate</CODE> environment uses the <CODE>enumi</CODE> through
<CODE>enumiv</CODE> counters (see section <A HREF="latex2e.html#SEC3">Counters</A>). The type of numbering can be
changed by redefining <CODE>\theenumi</CODE> etc.

Figures are objects that are not part of the normal text, and are
usually "floated" to a convenient place, like the top of a page.
Figures will not be split between two pages.
</P>
<P>
The optional argument <CODE>[placement]</CODE> determines where LaTeX will try
to place your figure. There are four places where LaTeX can possibly
put a float:
</P>
<OL>
<LI>
<CODE>h</CODE> (Here) - at the position in the text where the figure
environment appears.
<LI>
<CODE>t</CODE> (Top) - at the top of a text page.
<LI>
<CODE>b</CODE> (Bottom) - at the bottom of a text page.
<LI>
<CODE>p</CODE> (Page of floats) - on a separate float page, which is a page
containing no text, only floats.
</OL>

</P>
<P>
Footnotes in a <CODE>minipage</CODE> environment are handled in a way that is
particularly useful for putting footnotes in figures or tables. A
<CODE>\footnote</CODE> or <CODE>\footnotetext</CODE> command puts the footnote at
the bottom of the minipage instead of at the bottom of the page, and it
uses the <CODE>mpfootnote</CODE> counter instead of the ordinary

\end{picture}
</PRE>
<P>
The <CODE>picture</CODE> environment allows you to create just about any kind
of picture you want containing text, lines, arrows and circles. You
tell LaTeX where to put things in the picture by specifying their
coordinates. A coordinate is a number that may have a decimal point and
a minus sign -- a number like <CODE>5</CODE>, <CODE>2.3</CODE> or <CODE>-3.1416</CODE>. A
coordinate specifies a length in multiples of the unit length
<CODE>\unitlength</CODE>, so if <CODE>\unitlength</CODE> has been set to <CODE>1cm</CODE>,
then the coordinate 2.54 specifies a length of 2.54 centimetres. You
can change the value of <CODE>\unitlength</CODE> anywhere you want, using the
<CODE>\setlength</CODE> command, but strange things will happen if you try
changing it inside the picture environment.
</P>
<P>
A position is a pair of coordinates, such as <CODE>(2.4,-5)</CODE>, specifying
the point with x-coordinate <CODE>2.4</CODE> and y-coordinate <CODE>-5</CODE>.
Coordinates are specified in the usual way with respect to an origin,
which is normally at the lower-left corner of the picture. Note that
when a position appears as an argument, it is not enclosed in braces;
the parentheses serve to delimit the argument.
</P>
<P>
The <CODE>picture</CODE> environment has one mandatory argument, which is a
<CODE>position</CODE>. It specifies the size of the picture. The environment
produces a rectangular box with width and height determined by this
argument's x- and y-coordinates.
</P>
<P>
The <CODE>picture</CODE> environment also has an optional <CODE>position</CODE>
argument, following the <CODE>size</CODE> argument, that can change the
origin. (Unlike ordinary optional arguments, this argument is not
contained in square brackets.) The optional argument gives the
coordinates of the point at the lower-left corner of the picture
(thereby determining the origin). For example, if <CODE>\unitlength</CODE>
has been set to <CODE>1mm</CODE>, the command
<PRE>
\begin{picture}(100,200)(10,20)
</PRE>
<P>
produces a picture of width 100 millimetres and height 200
millimetres, whose lower-left corner is the point (10,20) and whose
upper-right corner is therefore the point (110,220). When you first
draw a picture, you will omit the optional argument, leaving the origin
at the lower-left corner. If you then want to modify your picture by
shifting everything, you just add the appropriate optional argument.
</P>
<P>
The environment's mandatory argument determines the nominal size of the
picture. This need bear no relation to how large the picture really is;
LaTeX will happily allow you to put things outside the picture, or even
off the page. The picture's nominal size is used by LaTeX in determining
how much room to leave for it.
</P>
<P>
Everything that appears in a picture is drawn by the <CODE>\put</CODE>
command. The command
<PRE>
\put (11.3,-.3){...}
</PRE>
<P>
puts the object specified by <CODE>...</CODE> in the picture, with its
reference point at coordinates (11.3,-.3). The reference points for
various objects will be described below.
</P>
<P>
The <CODE>\put</CODE> command creates an <STRONG>LR box</STRONG>. You can put anything
in the text argument of the <CODE>\put</CODE> command that you'd put into the
argument of an <CODE>\mbox</CODE> and related commands. When you do this, the
reference point will be the lower left corner of the box.

<DL COMPACT>
<DT><CODE>\=</CODE>
<DD>
<A NAME="IDX129"></A>
Sets a tab stop at the current position.
<DT><CODE>\></CODE>
<DD>
<A NAME="IDX130"></A>
Advances to the next tab stop.
<DT><CODE>\<</CODE>
<DD>
<A NAME="IDX131"></A>
This command allows you to put something to the left of the
local margin without changing the margin.
Can only be used at the start of the line.
<DT><CODE>\+</CODE>
<DD>
<A NAME="IDX132"></A>
Moves the left margin of the next and all the
following commands one tab stop to the right.
<DT><CODE>\-</CODE>
<DD>
<A NAME="IDX133"></A>
Moves the left margin of the next and all the
following commands one tab stop to the left.
<DT><CODE>\'</CODE>
<DD>
<A NAME="IDX134"></A>
Moves everything that you have typed so far in the
current column, i.e. everything from the most recent <CODE>\></CODE>,
<CODE>\<</CODE>, <CODE>\'</CODE>, <CODE>\\</CODE>, or <CODE>\kill</CODE> command, to the right
of the previous column, flush against the current column's tab stop.
<DT><CODE>\`</CODE>
<DD>
<A NAME="IDX135"></A>
Allows you to put text flush right against any tab stop, including tab
stop 0. However, it can't move text to the right of the last column
because there's no tab stop there. The <CODE>\`</CODE> command moves all the
text that follows it, up to the <CODE>\\</CODE> or <CODE>\end{tabbing}</CODE>
command that ends the line, to the right margin of the tabbing
environment. There must be no <CODE>\></CODE> or <CODE>\'</CODE> command between
the <CODE>\`</CODE> and the command that ends the line.
<DT><CODE>\kill</CODE>
<DD>
<A NAME="IDX136"></A>
Sets tab stops without producing
text. Works just like <CODE>\\</CODE> except that it throws away the
current line instead of producing output for it. The effect of any
<CODE>\=</CODE>, <CODE>\+</CODE> or <CODE>\-</CODE> commands in that line remain in
effect.
<DT><CODE>\pushtabs</CODE>
<DD>
<A NAME="IDX137"></A>
Saves all current tab stop positions. Useful for
temporarily changing tab stop positions in the middle of a
<CODE>tabbing</CODE> environment.
<DT><CODE>\pushtabs</CODE>
<DD>
<A NAME="IDX138"></A>
Restores the tab stop positions saved by the last <CODE>\pushtabs</CODE>.
<DT><CODE>\a</CODE>
<DD>
<A NAME="IDX139"></A>
In a <CODE>tabbing</CODE> environment, the commands <CODE>\=</CODE>, <CODE>\'</CODE> and
<CODE>\`</CODE> do not produce accents as normal. Instead, the commands
<CODE>\a=</CODE>, <CODE>\a'</CODE> and <CODE>\a`</CODE> are used.

Tables are objects that are not part of the normal text, and are
usually "floated" to a convenient place, like the top of a page.
Tables will not be split between two pages.

a float:

environment appears.
<LI>
<CODE>t</CODE> : Top - at the top of a text page.
<LI>
<CODE>b</CODE> : Bottom - at the bottom of a text page.
<LI>
<CODE>p</CODE> : Page of floats - on a separate float page, which is a page
containing no text, only floats.
</UL>

These environments produce a box consisting of a sequence of rows of
items, aligned vertically in columns. The mandatory and optional
arguments consist of:
</P>
<DL COMPACT>
<DT><CODE>width</CODE>
<DD>
Specifies the width of the <CODE>tabular*</CODE> environment. There must be
rubber space between columns that can stretch to fill out the specified
width.
<DT><CODE>pos</CODE>
<DD>
Specifies the vertical position; default is alignment on the centre of
the environment.
<UL>
<LI>
<CODE>t</CODE> - align on top row
<LI>
<CODE>b</CODE> - align on bottom row
</UL>
<DT><CODE>cols</CODE>
<DD>
Specifies the column formatting. It consists of a sequence of the
following specifiers, corresponding to the sequence of columns and
intercolumn material.
<UL>
<LI>
<CODE>l</CODE> - A column of left-aligned items.
<LI>
<CODE>r</CODE> - A column of right-aligned items.
<LI>
<CODE>c</CODE> - A column of centred items.
<LI>
<CODE>|</CODE> - A vertical line the full height and depth of the environment.
<LI>
<CODE>@{text}</CODE> - This inserts <CODE>text</CODE> in every row. An @-expression
suppresses the intercolumn space normally inserted between columns; any
desired space between the inserted text and the adjacent items must be
included in text. An <CODE>\extracolsep{wd}</CODE> command in an
@-expression causes an extra space of width <CODE>wd</CODE> to appear to the
left of all subsequent columns, until countermanded by another
<CODE>\extracolsep</CODE> command. Unlike ordinary intercolumn space, this
extra space is not suppressed by an @-expression. An
<CODE>\extracolsep</CODE> command can be used only in an @-expression in the
<CODE>cols</CODE> argument.
<LI>
<CODE>p{wd}</CODE> - Produces a column with each item typeset in a parbox of
width <CODE>wd</CODE>, as if it were the argument of a <CODE>\parbox[t]{wd}</CODE>
command. However, a <CODE>\\</CODE> may not appear in the item, except in the
following situations:
<OL>
<LI>
inside an environment like <CODE>minipage</CODE>, <CODE>array</CODE>, or <CODE>tabular</CODE>.
<LI>
inside an explicit <CODE>\parbox</CODE>.
<LI>
in the scope of a <CODE>\centering</CODE>, <CODE>\raggedright</CODE>, or <CODE>\raggedleft</CODE>
declaration. The latter declarations must appear inside braces or an
environment when used in a <CODE>p</CODE>-column element.
</OL>
<LI>
<CODE>*{num}{cols}</CODE> - Equivalent to <CODE>num</CODE> copies of
<CODE>cols</CODE>, where <CODE>num</CODE> is any positive integer and <CODE>cols</CODE> is
any list of column-specifiers, which may contain another
<CODE>*-expression</CODE>.
</UL>
</DL>
<P>
These commands can be used inside a <CODE>tabular</CODE> environment:

<H4><A NAME="SEC65" HREF="latex2e_toc.html#TOC65">\cline</A></H4>
<P>
<A NAME="IDX146"></A>
</P>
<P>
<CODE>\cline{i-j}</CODE>
</P>
<P>
The <CODE>\cline</CODE> command draws horizontal lines across the columns
specified, beginning in column <CODE>i</CODE> and ending in column <CODE>j</CODE>,
which are identified in the mandatory argument.
</P>
<H4><A NAME="SEC66" HREF="latex2e_toc.html#TOC66">\hline</A></H4>
<P>
<A NAME="IDX147"></A>
</P>
<P>
The <CODE>\hline</CODE> command will draw a horizontal line the width of the
table. It's most commonly used to draw a line at the top, bottom, and
between the rows of the table.
</P>
<H4><A NAME="SEC67" HREF="latex2e_toc.html#TOC67">\multicolumn</A></H4>
<P>
<A NAME="IDX148"></A>
</P>
<P>
<CODE>\multicolumn{cols}{pos}{text}</CODE>
</P>
<P>
The <CODE>\multicolumn</CODE> is used to make an entry that spans several
columns. The first mandatory argument, <CODE>cols</CODE>, specifies the
number of columns to span. The second mandatory argument, <CODE>pos</CODE>,
specifies the formatting of the entry; <CODE>c</CODE> for centred, <CODE>l</CODE>
for flushleft, <CODE>r</CODE> for flushright. The third mandatory argument,
<CODE>text</CODE>, specifies what text is to make up the entry.
</P>
<H4><A NAME="SEC68" HREF="latex2e_toc.html#TOC68">\vline</A></H4>
<P>
<A NAME="IDX149"></A>
</P>
<P>
The <CODE>\vline</CODE> command will draw a vertical line extending the full
height and depth of its row. An <CODE>\hfill</CODE> command can be used to
move the line to the edge of the column. It can also be used in an
@-expression.

</PRE>
<P>
The <CODE>thebibliography</CODE> environment produces a bibliography or
reference list. In the <CODE>article</CODE> class, this reference list is
labelled "References"; in the <CODE>report</CODE> class, it is labelled
"Bibliography".
</P>
<UL>
<LI>

<A NAME="IDX152"></A>
</P>
<P>
<CODE>\bibitem[label]{cite_key}</CODE>
</P>
<P>
The <CODE>\bibitem</CODE> command generates an entry labelled by <CODE>label</CODE>.
If the <CODE>label</CODE> argument is missing, a number is generated as the
<CODE>label</CODE>, using the <CODE>enumi</CODE> counter. The <CODE>cite_key</CODE> is
any sequence of letters, numbers, and punctuation symbols not containing
a comma. This command writes an entry on the <TT>`.aux'</TT> file
containing <CODE>cite_key</CODE> and the item's <CODE>label</CODE>. When this
<TT>`.aux'</TT> file is read by the <CODE>\begin{document}</CODE> command, the
item's <CODE>label</CODE> is associated with <CODE>cite_key</CODE>, causing the
reference to <CODE>cite_key</CODE> by a <CODE>\cite</CODE> command to produce the
associated <CODE>label</CODE>.
</P>

</P>
<P>
The <CODE>key_list</CODE> argument is a list of citation keys. This command
generates an in-text citation to the references associated with the keys
in <CODE>key_list</CODE> by entries on the <TT>`.aux'</TT> file read by the
<CODE>\begin{document}</CODE> command.
</P>
<P>
The optional <CODE>text</CODE> argument will appear after the citation,
i.e. <CODE>\cite[p. 2]{knuth}</CODE> might produce `[Knuth, p. 2]'.

where <CODE>style</CODE> refers to a file <CODE>style.bst</CODE>, which defines how
your citations will look. The standard styles distributed with BibTeX
are:
</P>
<DL COMPACT>
<DT><CODE>alpha</CODE>
<DD>
Sorted alphabetically. Labels are formed from name of author and year of
publication.
<DT><CODE>plain</CODE>

Sorted alphabetically. Labels are numeric.
<DT><CODE>unsrt</CODE>
<DD>
Like <CODE>plain</CODE>, but entries are in order of citation.

Like <CODE>plain</CODE>, but more compact labels.
</DL>
<P>
In addition, numerous other BibTeX style files exist tailored to the
demands of various publications.
</P>
<P>
The argument to <CODE>\bibliography</CODE> refers to the file

<P>
You can use LaTeX to typeset letters, both personal and business. The
<CODE>letter</CODE> document class is designed to make a number of letters at
once, although you can make just one if you so desire.
</P>
<P>
Your <TT>`.tex'</TT> source file has the same minimum commands as the other
document classes, i.e., you must have the following commands as a
minimum:
</P>
<PRE>
\documentclass{letter}
\begin{document}
... letters ...
\end{document}
</PRE>
<P>
Each letter is a <CODE>letter</CODE> environment, whose argument is the name
and address of the recipient. For example, you might have:
</P>
<PRE>
\begin{letter}{Mr. Joe Smith\\ 2345 Princess St.
\\ Edinburgh, EH1 1AA}
...
\end{letter}
</PRE>
<P>
The letter itself begins with the <CODE>\opening</CODE> command. The text of
the letter follows. It is typed as ordinary LaTeX input. Commands that
make no sense in a letter, like <CODE>\chapter</CODE>, do not work. The letter
closes with a <CODE>\closing</CODE> command.
</P>
<P>
After the <CODE>closing</CODE>, you can have additional material. The
<CODE>\cc</CODE> command produces the usual "cc: ...". There's also a similar
<CODE>\encl</CODE> command for a list of enclosures. With both these commands,
use <CODE>\\</CODE> to separate the items.
</P>
<P>
These commands are used with the <CODE>letter</CODE> class:
</P>
<H3><A NAME="SEC92" HREF="latex2e_toc.html#TOC92">\address</A></H3>
<P>
<A NAME="IDX197"></A>
</P>
<P>
<CODE>\address{Return address}</CODE>
</P>
<P>
The return address, as it should appear on the letter and the envelope.
Separate lines of the address should be separated by <CODE>\\</CODE> commands.
If you do not make an <CODE>\address</CODE> declaration, then the letter will
be formatted for copying onto your organisation's standard letterhead.
(See section <A HREF="latex2e.html#SEC1">Overview of LaTeX and Local Guide</A>, for details on your local implementation). If you
give an <CODE>\address</CODE> declaration, then the letter will be formatted
as a personal letter.

The first thing LaTeX does when processing ordinary text is to
translate your input file into a string of glyphs and spaces. To
produce a printed document, this string must be broken into lines, and
these lines must be broken into pages. In some environments, you do the
line breaking yourself with the <CODE>\\</CODE> command, but LaTeX usually
does it for you.

<CODE>\\[*][extra-space]</CODE>
</P>
<P>
The <CODE>\\</CODE> command tells LaTeX to start a new line. It has an
optional argument, <CODE>extra-space</CODE>, that specifies how much extra
vertical space is to be inserted before the next line. This can be a
negative amount.
</P>
<P>
The <CODE>\\*</CODE> command is the same as the ordinary <CODE>\\</CODE> command
except that it tells LaTeX not to start a new page after the line.

The <CODE>\-</CODE> command tells LaTeX that it may hyphenate the word at that

correct hyphenation points. The <CODE>\-</CODE> command is used for the
exceptional cases.

When LaTeX is processing your input text, it is always in one of three
modes:
</P>
<UL>
<LI>
Paragraph mode
<LI>
Math mode
<LI>
Left-to-right mode, called LR mode for short
</UL>
<P>
LaTeX changes mode only when it goes up or down a staircase to a
different level, though not all level changes produce mode changes.
Mode changes occur only when entering or leaving an environment, or when
LaTeX is processing the argument of certain text-producing commands.
</P>
<P>
"Paragraph mode" is the most common; it's the one LaTeX is in when
processing ordinary text. In that mode, LaTeX breaks your text into
lines and breaks the lines into pages. LaTeX is in "math mode" when
it's generating a mathematical formula. In "LR mode", as in paragraph
mode, LaTeX considers the output that it produces to be a string of
words with spaces between them. However, unlike paragraph mode, LaTeX
keeps going from left to right; it never starts a new line in LR mode.
Even if you put a hundred words into an <CODE>\mbox</CODE>, LaTeX would keep
typesetting them from left to right inside a single box, and then
complain because the resulting box was too wide to fit on the line.
</P>
<P>
LaTeX is in LR mode when it starts making a box with an <CODE>\mbox</CODE>
command. You can get it to enter a different mode inside the box - for
example, you can make it enter math mode to put a formula in the box.
There are also several text-producing commands and environments for
making a box that put LaTeX in paragraph mode. The box make by one of
these commands or environments will be called a <CODE>parbox</CODE>. When
LaTeX is in paragraph mode while making a box, it is said to be in
"inner paragraph mode". Its normal paragraph mode, which it starts out
in, is called "outer paragraph mode".

<P>
In addition to providing the heading in the text, the mandatory argument
of the sectioning command can appear in two other places:
</P>
<OL>
<LI>
The table of contents
<LI>
The running head at the top of the page
</OL>
<P>
You may not want the same thing to appear in these other two places as
appears in the text heading. To handle this situation, the sectioning
commands have an <CODE>optional</CODE> argument that provides the text for
these other two purposes.
</P>
<P>
All sectioning commands have <CODE>*</CODE>-forms that print a <I>title</I>,
but do not include a number and do not make an entry in the table of
contents.

<CODE>\parbox[position][height][inner-pos]{width}{text}</CODE>
</P>
<P>
A <CODE>parbox</CODE> is a box whose contents are created in <CODE>paragraph</CODE>
mode. The <CODE>\parbox</CODE> has two mandatory arguments:
</P>
<UL>
<LI>
<CODE>width</CODE> - specifies the width of the parbox, and
<LI>
<CODE>text</CODE> - the text that goes inside the parbox.
</UL>
<P>
LaTeX will position a <CODE>parbox</CODE> so its centre lines up with the centre of
the text line. The optional <I>position</I> argument allows you
to line up either the top or bottom line in the parbox (default is top).
</P>
<P>
If the <I>height</I> argument is not given, the box will have the natural
height of the text.
</P>
<P>
The <I>inner-pos</I> argument controls the placement of the text inside the
box. If it is not specified, <I>position</I> is used.
</P>
<UL>
<LI>
<CODE>t</CODE> -- text is placed at the top of the box.
<LI>
<CODE>c</CODE> -- text is centred in the box.
<LI>
<CODE>b</CODE> -- text is placed at the bottom of the box.
<LI>
<CODE>s</CODE> -- stretch vertically. The text must contain
vertically stretchable space for this to work.
</UL>
<P>
A <CODE>\parbox</CODE> command is used for a parbox containing a small piece
of text, with nothing fancy inside. In particular, you shouldn't use
any of the paragraph-making environments inside a <CODE>\parbox</CODE>
argument. For larger pieces of text, including ones containing a
paragraph-making environment, you should use a <CODE>minipage</CODE>
environment See section <A HREF="latex2e.html#SEC46">minipage</A>.

<CODE>\raisebox{distance}[extend-above][extend-below]{text}</CODE>
</P>
<P>
The <CODE>\raisebox</CODE> command is used to raise or lower text. The first
mandatory argument specifies how high the text is to be raised (or
lowered if it is a negative amount). The text itself is processed in
<CODE>LR mode</CODE>.
</P>
<P>
Sometimes it's useful to make LaTeX think something has a different
size than it really does - or a different size than LaTeX would
normally think it has. The <CODE>\raisebox</CODE> command lets you tell
LaTeX how tall it is.
</P>
<P>
The first optional argument, <CODE>extend-above</CODE>, makes LaTeX think
that the text extends above the line by the amount specified. The
second optional argument, <CODE>extend-below</CODE>, makes LaTeX think that
the text extends below the line by the amount specified.

The following characters play a special role in LaTeX and are called
"special printing characters", or simply "special characters".
</P>
<PRE>
# $ % & ~ _ ^ \ { }
</PRE>
<P>
Whenever you put one of these special characters into your file, you are
doing something special. If you simply want the character to be printed
just as any other letter, include a <CODE>\</CODE> in front of the character.
For example, <CODE>\$</CODE> will produce <CODE>$</CODE> in your output.
</P>
<P>
One exception to this rule is the <CODE>\</CODE> itself because <CODE>\\</CODE> has
its own special meaning. A <CODE>\</CODE> is produced by typing
<CODE>$\backslash$</CODE> in your file.
</P>
<P>
Also, <CODE>\~</CODE> means `place a tilde accent over the following letter',
so you will probably want to use <CODE>\verb</CODE> instead.
</P>
<P>
<A NAME="IDX346"></A>
<A NAME="IDX347"></A>
<A NAME="IDX348"></A>
</P>
<P>
In addition, you can access any character of a font once you know its
number by using the <CODE>\symbol</CODE> command. For example, the character
used for displaying spaces in the <CODE>\verb*</CODE> command has the code
decimal 32, so it can be typed as <CODE>\symbol{32}</CODE>.
</P>
<P>
You can also specify octal numbers with <CODE>'</CODE> or hexadecimal numbers
with <CODE>"</CODE>, so the previous example could also be written as
<CODE>\symbol{'40}</CODE> or <CODE>\symbol{"20}</CODE>.

A large document requires a lot of input. Rather than putting the whole

<P>
The <CODE>\include</CODE> command is used in conjunction with the

<CODE>file</CODE> argument is the first name of a file, denoting
<TT>`file.tex'</TT>. If <CODE>file</CODE> is one the file names in the file list

except that if the file <TT>`file.tex'</TT> does not exist, then a warning

in <CODE>msg</CODE> that are defined with <CODE>\newcommand</CODE> or
<CODE>\renewcommand</CODE> are replaced by their definitions before being
printed.
</P>
<P>
LaTeX's usual rules for treating multiple spaces as
a single space and ignoring spaces after a command name apply to
<CODE>msg</CODE>. A <CODE>\space</CODE> command in <CODE>msg</CODE> causes a single space
to be printed. A <CODE>^^J</CODE> in <CODE>msg</CODE> prints a newline.

The following type style commands are supported by LaTeX.
</P>
<P>
These commands are used like <CODE>\textit{italics text}</CODE>. The
corresponding command in parenthesis is the "declaration form", which
takes no arguments. The scope of the declaration form lasts until the
next type style command or the end of the current group.
</P>
<P>
The declaration forms are cumulative; i.e., you can say
<CODE>\sffamily\bfseries</CODE> to get sans serif boldface.
</P>
<P>
You can also use the environment form of the declaration forms; e.g.
<CODE>\begin{ttfamily}...\end{ttfamily}</CODE>.

ones. For full details, you should consult Chapter 7 of <CITE>The LaTeX
Companion</CITE>.
</P>
<DL COMPACT>
<DT><CODE>\fontencoding{enc}</CODE>
<DD>
<A NAME="IDX416"></A>
Select font encoding. Valid encodings include <CODE>OT1</CODE> and <CODE>T1</CODE>.
<DT><CODE>\fontfamily{family}</CODE>
<DD>
<A NAME="IDX417"></A>
Select font family. Valid families include:
<UL>
<LI><CODE>cmr</CODE> for Computer Modern Roman
<LI><CODE>cmss</CODE> for Computer Modern Sans Serif
<LI><CODE>cmtt</CODE> for Computer Modern Typewriter
</UL>
and numerous others.
<DT><CODE>\fontseries{series}</CODE>
<DD>
<A NAME="IDX418"></A>
Select font series. Valid series include:
<UL>
<LI><CODE>m</CODE> Medium (normal)
<LI><CODE>b</CODE> Bold
<LI><CODE>c</CODE> Condensed
<LI><CODE>bc</CODE> Bold condensed
<LI><CODE>bx</CODE> Bold extended
</UL>
and various other combinations.
<DT><CODE>\fontshape{shape}</CODE>
<DD>
<A NAME="IDX419"></A>
Select font shape. Valid shapes are:
<UL>
<LI><CODE>n</CODE> Upright (normal)
<LI><CODE>it</CODE> Italic
<LI><CODE>sl</CODE> Slanted (oblique)
<LI><CODE>sc</CODE> Small caps
<LI><CODE>ui</CODE> Upright italics
<LI><CODE>ol</CODE> Outline
</UL>
The two last shapes are not available for most font families.
<DT><CODE>\fontsize{size}{skip}</CODE>
<DD>
<A NAME="IDX420"></A>
Set font size. The first parameter is the font size to switch to; the
second is the <CODE>\baselineskip</CODE> to use. The unit of both parameters
defaults to pt. A rule of thumb is that the baselineskip should be 1.2
times the font size.
<DT><CODE>\selectfont</CODE>
<DD>
<A NAME="IDX421"></A>
The changes made by calling the four font commands described above do
not come into effect until <CODE>\selectfont</CODE> is called.
<DT><CODE>\usefont{enc}{family}{series}{shape}</CODE>
<DD>
<A NAME="IDX422"></A>
Equivalent to calling <CODE>\fontencoding</CODE>, <CODE>\fontfamily</CODE>,
<CODE>\fontseries</CODE> and <CODE>\fontshape</CODE> with the given parameters, followed by <CODE>\selectfont</CODE>.
</DL>
<H1><A NAME="SEC182" HREF="latex2e_toc.html#TOC182">Parameters</A></H1>
<P>
The input file specification indicates the file to be formatted; TeX
uses <TT>`.tex'</TT> as a default file extension. If you omit the input file
entirely, TeX accepts input from the terminal. You specify command
options by supplying a string as a parameter to the command; e.g.
</P>
<P>
<CODE>latex "\scrollmode\input foo.tex"</CODE>
</P>
<P>
will process <TT>`foo.tex'</TT> without pausing after every error.
</P>
<P>
Output files are always created in the current directory. When you fail
to specify an input file name, TeX bases the output names on the file
specification associated with the logical name TEX_OUTPUT, typically
<CODE>texput.log</CODE>.
