Literals

NameExampleClassDescriptionConstraints
String literal'text'
'line1\nline2'
'{system.cancel}'
STRING[N], TEXTA 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.
