AUTO_LEXER Language-Dependent Attributes

AUTO_LEXER provides language-dependent attributes for the languages specified in Table 2-15. Table 2-17 lists the language-dependent attributes available in the AUTO_LEXER. The <language> variable in the attribute name refers to any of the supported language names that are listed in Table 2-15.

Note: Attribute names must not exceed 30 characters. Therefore, where the <language> variable is specified, the language name may need to be abbreviated in certain instances. For example, traditional_chinese should be abbreviated to trad_chinese and simplified_chinese should be abbreviated to simp_chinese.
