| 5 | =head1 NAME |
| 6 | |
| 7 | locale - Perl pragma to use and avoid POSIX locales for built-in operations |
| 8 | |
| 9 | =head1 SYNOPSIS |
| 10 | |
| 11 | @x = sort @y; # ASCII sorting order |
| 12 | { |
| 13 | use locale; |
| 14 | @x = sort @y; # Locale-defined sorting order |
| 15 | } |
| 16 | @x = sort @y; # ASCII sorting order again |
| 17 | |
| 18 | =head1 DESCRIPTION |
| 19 | |
| 20 | This pragma tells the compiler to enable (or disable) the use of POSIX |
| 21 | locales for built-in operations (LC_CTYPE for regular expressions, and |
| 22 | LC_COLLATE for string comparison). Each "use locale" or "no locale" |
| 23 | affects statements to the end of the enclosing BLOCK. |
| 24 | |
| 25 | See L<perllocale> for more detailed information on how Perl supports |
| 26 | locales. |
