### Reference Syntax

Most often, an Info cross reference looks like this:

    *Note node-name::.

or like this

    *Note cross-reference-name: node-name.

In TeX, a cross reference looks like this:

> See Section section-number [node-name], page page.

or like this

> See Section section-number [title-or-topic], page page.

The `@xref` command does not generate a period or comma to end the cross reference in either the Info file or the printed output. You must write that period or comma yourself; otherwise, Info will not recognize the end of the reference. (The `@pxref` command works differently. See `@pxref`.)

> Please note: A period or comma must follow the closing brace of an `@xref`. It is required to terminate the cross reference. This period or comma will appear in the output, both in the Info file and in the printed manual.

`@xref` must refer to an Info node by name. Use `@node` to define the node (see Writing a Node).

`@xref` is followed by several arguments inside braces, separated by commas. Whitespace before and after these commas is ignored.

A cross reference requires only the name of a node; but it may contain up to four additional arguments. Each of these variations produces a cross reference that looks somewhat different.

> Please note: Commas separate arguments in a cross reference; avoid including them in the title or other part lest the formatters mistake them for separators.
