<h3 class="section">6.4 Creating Pointers with <code>makeinfo</code></h3>
<p><a name="index-Creating-pointers-with-_0040code_007bmakeinfo_007d-330"></a><a name="index-Pointer-creation-with-_0040code_007bmakeinfo_007d-331"></a><a name="index-Automatic-pointer-creation-with-_0040code_007bmakeinfo_007d-332"></a>
The <code>makeinfo</code> program has a feature for automatically
determining node pointers for a hierarchically organized document. We
highly recommend using it.
<p>When you take advantage of this feature, you do not need to write the
`Next', `Previous', and `Up' pointers after the name of a node.
However, you must write a sectioning command, such as <code>@chapter</code>
or <code>@section</code>, on the line immediately following each truncated
<code>@node</code> line (except that comment lines may intervene).
<p>In addition, you must follow the `Top' <code>@node</code> line with a line
beginning with <code>@top</code> to mark the `Top' node in the
file. See <a href="makeinfo-top.html#makeinfo-top"><code>@top</code></a>.
<p>Finally, you must write the name of each node (except for the `Top'
node) in a menu that is one or more hierarchical levels above the
node's hierarchical level.
<p><a name="index-Detail-menu-333"></a><a name="index-detailmenu-334"></a>If you use a detailed menu in your master menu (see <a href="Master-Menu-Parts.html#Master-Menu-Parts">Master Menu Parts</a>), mark it with the <code>@detailmenu @dots{} @end
detailmenu</code> environment, or <samp><span class="command">makeinfo</span></samp> will get confused,
typically about the last and/or first node in the document.
<p>This implicit node pointer creation feature in <code>makeinfo</code>
relieves you from the need to update menus and pointers manually or
with Texinfo mode commands. (See <a href="Updating-Nodes-and-Menus.html#Updating-Nodes-and-Menus">Updating Nodes and Menus</a>.)
<p>In most cases, you will want to take advantage of this feature and not
redundantly specify node pointers. However, Texinfo documents are not
required to be organized hierarchically or in fact to contain
sectioning commands at all (for example, if you never intend the
document to be printed). The special procedure for handling the short
text before a menu (see <a href="Menus.html#Menus">Menus</a>) also disables this
feature, for that group of nodes. In those cases, you will need to
explicitly specify all pointers.
