String Literals

String literals are string values surrounded by single or double quotes. Double-quoted strings are subject to the backslash, but single-quoted strings do not require a backslash, except for \' and \\.

You can embed single quotes and backslashes into single-quoted strings.

To include other backslash (escape) sequences, such as \t (tab), you must use the double-quoted form.

Precede single-quoted strings with a space between the string and its preceding word, since single quotes are allowed in identifiers.
