| String literal | 'text'
'line1\nline2'
'{system.cancel}' | STRING[N], TEXT | A sequence of characters enclosed in single quotes, allowing to use the special sequences \n, \r, \t. To specify single quote and backslash characters, use the escape sequences \' and \\. A string literal can also be a localizable string. In this case the literal's class will be TEXT, and instead of the characters { and } it is necessary to use the special sequences \{ and \} respectively. If a string literal does not use localization capabilities, then the literal's class will be STRING[N] where N is the number of characters in the string. | |
