package locale; =head1 NAME locale - Perl pragma to use and avoid POSIX locales for built-in operations =head1 SYNOPSIS @x = sort @y; # ASCII sorting order { use locale; @x = sort @y; # Locale-defined sorting order } @x = sort @y; # ASCII sorting order again =head1 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. =cut sub import { $^H |= 0x800; } sub unimport { $^H &= ~0x800; } 1;
