# NAME

locale - Perl pragma to use and avoid POSIX locales for built-in operations

# SYNOPSIS

        @x = sort @y;       # ASCII sorting order
        {
            use locale;
            @x = sort @y;   # Locale-defined sorting order
        }
        @x = sort @y;       # ASCII sorting order again

# DESCRIPTION

This pragma tells the compiler to enable (or disable) the use of POSIX locales for built-in operations (LC_CTYPE for regular expressions, and LC_COLLATE for string comparison). Each ``use locale'' or ``no locale'' affects statements to the end of the enclosing BLOCK.
