Specifications

[ ] In command format descriptions, brackets indicate optional
elements. You can choose one, none, or all of the options.
(Brackets are not optional, however, in the syntax of a directory
name in an OpenVMS file specification or in the syntax of a
substring specification in an assignment statement.)
{ } In command format descriptions, braces surround a required
choice of options; you must choose one of the options listed.
boldface text Boldface text represents the introduction of a new term or the
name of an argument, an attribute, or a reason (user action
that triggers a callback).
Boldface text is also used to show user input in Bookreader
versions of the manual.
italic text Italic text emphasizes important information and indicates
complete titles of manuals and variables. Variables include
information that varies in system messages (Internal error
number), in command lines (/PRODUCER=name), and in
command parameters in text (where device-name contains up
to five alphanumeric characters).
UPPERCASE TEXT Uppercase text indicates a command, the name of a routine,
the name of a file, or the abbreviation for a system privilege.
struct Monospace type in text identifies the following C programming
language elements: keywords, the names of independently
compiled external functions and files, syntax summaries, and
references to variables or identifiers introduced in an example.
- A hyphen in code examples indicates that additional
arguments to the request are provided on the line that follows.
numbers All numbers in text are assumed to be decimal unless
otherwise noted. Nondecimal radixes—binary, octal, or
hexadecimal—are explicitly indicated.
