Accessibility of Code Examples in Documentation

JAWS, a Windows screen reader, may not always correctly read the code examples in this document. The conventions for writing code require that closing braces should appear on an otherwise empty line; however, JAWS may not always read a line of text that consists solely of a bracket or brace.

Conventions Used in This Guide

The following typographic conventions are used in this guide:

Convention Description


Uppercase text indicates case-insensitive file names or directory names, commands, command keywords, initialization parameters, data types, table names, or object names. Enter text exactly as spelled.

UPPERCASE in Code Examples

Uppercase words in example statements indicate the keywords within Oracle SQL. When you issue statements, however, keywords are not case sensitive.

lowercase in Code Examples

Lowercase words in example statements indicate words supplied only for the context of the example. For example, lowercase words may indicate the name of a table, column, or file.


In text, key names are represented by uppercase letters enclosed in brackets, for example [RETURN].

In command syntax, brackets indicate optional items: cvtcrt termname [outfile]


Italic type indicates variables, including variable portions of file names. It is also used for emphasis.

Code Examples

Monospace type indicates commands, directory names, user names, path names, file names, and text quoted from screen output.

Monospace text must be entered exactly as shown. Example statements may include punctuation, such as commas or quotation marks. All punctuation in example statements is required. All example statements terminate with a semicolon (;). Depending on the application, a semicolon or other terminator may or may not be required to end a statement.


Boldface type indicates emphasis.

{ }

Braces indicate required items:

.DEFINE {macro1}.

Do not enter the braces.


A vertical line indicates a choice within braces or brackets:
SIZE filesize [K|M]

Do not enter the vertical bar.


Ellipses indicate an arbitrary number of similar items:
CHKVAL fieldname value1 value2 ... valueN

Do not type the ellipsis.

SQL*Plus prompt

The SQL*Plus prompt, SQL>, appears in SQL statements and SQL*Plus command examples. Do not enter the prompt when entering the examples.

Microsoft-DOS prompt

The Microsoft-DOS prompt, >, appears in Microsoft-DOS command examples. Do not enter the prompt when entering the examples.

Storage measurements

Storage measurements use the following abbreviations:
K, for kilobyte which equals 1024 bytes
M, for megabyte which equals 1 048 576 bytes
G, for gigabyte which equals 1 073 741 824 bytes
