perlfunc root locale - Perl pragma to use and avoid POSIX locales for built-in operations <HR> <PRE> @x = sort @y; # ASCII sorting order { use locale; @x = sort @y; # Locale-defined sorting order } @x = sort @y; # ASCII sorting order again </PRE> <HR> 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. <HR>
