====Escape sequence====
Escape sequences are similar to escape characters, except they usually consist of some kind of mnemonic instead of just a single character. One use is in [[string literal]]s that include a doublequote (") character. For example in [[Perl]], the code:

<syntaxhighlight lang="perl">
print "Nancy said \x22Hello World!\x22 to the crowd.";  ### use \x22
</syntaxhighlight>

produces the same output as:

<syntaxhighlight lang="perl">
print "Nancy said \"Hello World!\" to the crowd.";      ### use escape char
</syntaxhighlight>

One drawback of escape sequences, when used by people, is the need to memorize the codes that represent individual characters (see also: [[character entity reference]], [[numeric character reference]]).
