The `@node' Command
===================

  A "node" is a segment of text that begins at an `@node' command and
continues until the next `@node' command.  The definition of node is
different from that for chapter or section.  A chapter may contain
sections and a section may contain subsections; but a node cannot
contain subnodes; the text of a node continues only until the next
`@node' command in the file.  A node usually contains only one chapter
structuring command, the one that follows the `@node' line.  On the
other hand, in printed output nodes are used only for cross references,
so a chapter or section may contain any number of nodes.  Indeed, a
chapter usually contains several nodes, one for each section,
subsection, and subsubsection.

  To create a node, write an `@node' command at the beginning of a
line, and follow it with four arguments, separated by commas, on the
rest of the same line.  These arguments are the name of the node, and
the names of the `Next', `Previous', and `Up' pointers, in that order.
You may insert spaces before each pointer if you wish; the spaces are
ignored.  You must write the name of the node, and the names of the
`Next', `Previous', and `Up' pointers, all on the same line.  Otherwise,
the formatters fail.  (Note: info, for more information
about nodes in Info.)

  Usually, you write one of the chapter-structuring command lines
immediately after an `@node' line--for example, an `@section' or
`@subsection' line.  (Note: Types of Structuring Commands.
)

     *Please note:* The GNU Emacs Texinfo mode updating commands work
     only with Texinfo files in which `@node' lines are followed by
     chapter structuring lines.  Note: Updating Requirements.

  TeX uses `@node' lines to identify the names to use for cross
references.  For this reason, you must write `@node' lines in a Texinfo
file that you intend to format for printing, even if you do not intend
to format it for Info.  (Cross references, such as the one at the end
of this sentence, are made with `@xref' and its related commands; see
Note: Cross References.)
