Constant width

Constant width italic

--

In code examples, a double hyphen begins a single-line comment that extends to the end of a line.

/* and */

In code examples, these characters delimit a multiline comment that can extend from one line to another.

In syntax descriptions, curly brackets enclose a set of items from which you must choose only one.

|

In syntax descriptions, a vertical bar separates the items enclosed in curly brackets, as in {TRUE | FALSE}.
