# locale(3pm)

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

## 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.
