HP Specific Features of lex and yacc
The following native language support features have been added to the HP
C lex and yacc tools:
* LC_CTYPE and LC_MESSAGES environment variable support in lex -
Determines the size of the characters and language in which
messages are displayed while you use lex.
* -m command line option for lex - Specifies that multibyte
characters may be used anywhere single byte characters are
allowed. You can intermix both 8-bit and 16-bit multibyte
characters in regular expressions if you enable the -m command
line option.
* -w command line option for lex - Includes all features in -m and
returns data in the form of the wchar_t data type.
* %l <locale> directive for lex - Specifies the locale at the
beginning of the definitions section. Any valid locale recognized
by the setlocale function can be used. This directive is similar
to using the LC_CTYPE environment variable. To receive wchar_t
support with %l, use the -w command line option.
* LC_CTYPE environment variable support in yacc - Determines the
native language set used by yacc and enables multibyte character
sets. Multibyte characters can appear in token names, on terminal
symbols, strings, comments, or anywhere ASCII characters can
appear, except as separators or special characters.
