.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
The \f(CW\*(C`Locale::Country\*(C'\fR module provides access to several code sets
that can be used for identifying countries, such as those defined in
\&\s-1ISO 3166\-1.\s0
.PP
Most of the routines take an optional additional argument which
specifies the code set to use. If not specified, the default \s-1ISO
3166\-1\s0 two-letter codes will be used.
.SH "SUPPORTED CODE SETS"
.IX Header "SUPPORTED CODE SETS"
There are several different code sets you can use for identifying
countries. A code set may be specified using either a name, or a
constant that is automatically exported by this module.
.PP
For example, the two are equivalent:
.PP
.Vb 2
\&   $country = code2country(\*(Aqjp\*(Aq,\*(Aqalpha\-2\*(Aq);
\&   $country = code2country(\*(Aqjp\*(Aq,LOCALE_CODE_ALPHA_2);
.Ve
.PP
The codesets currently supported are:
.IP "\fBalpha\-2, \s-1LOCALE_CODE_ALPHA_2\s0\fR" 4
.IX Item "alpha-2, LOCALE_CODE_ALPHA_2"
This is the set of two-letter (lowercase) codes from \s-1ISO 3166\-1,\s0 such
as 'tv' for Tuvalu.
.Sp
This is the default code set.
.IP "\fBalpha\-3, \s-1LOCALE_CODE_ALPHA_3\s0\fR" 4
.IX Item "alpha-3, LOCALE_CODE_ALPHA_3"
This is the set of three-letter (lowercase) codes from \s-1ISO 3166\-1,\s0
such as 'brb' for Barbados. These codes are actually defined and
maintained by the U.N. Statistics division.
.IP "\fBnumeric, \s-1LOCALE_CODE_NUMERIC\s0\fR" 4
.IX Item "numeric, LOCALE_CODE_NUMERIC"
This is the set of three-digit numeric codes from \s-1ISO 3166\-1,\s0 such as
064 for Bhutan. These codes are actually defined and maintained by the
U.N. Statistics division.
.Sp
If a 2\-digit code is entered, it is converted to 3 digits by prepending
a 0.
.IP "\fBfips\-10, \s-1LOCALE_CODE_FIPS\s0\fR" 4
.IX Item "fips-10, LOCALE_CODE_FIPS"
The \s-1FIPS 10\s0 data are two-letter (uppercase) codes assigned by the
National Geospatial-Intelligence Agency.
.IP "\fBdom, \s-1LOCALE_CODE_DOM\s0\fR" 4
.IX Item "dom, LOCALE_CODE_DOM"
The \s-1IANA\s0 is responsible for delegating management of the top level country
domains.  The country domains are the two-letter (lowercase) codes from \s-1ISO 3166\s0
with a few other additions.

.IP "\fBalias_code ( \s-1ALIAS, CODE\s0 [,CODESET] )\fR" 4
.IX Item "alias_code ( ALIAS, CODE [,CODESET] )"
Version 2.07 included 2 functions for modifying the internal data:
rename_country and alias_code. Both of these could be used only to
modify the internal data for country codes.
.Sp
As of 3.10, the internal data for all types of codes can be modified.
.Sp
The alias_code function is preserved for backwards compatibility, but
the following two are identical:
.Sp
.Vb 2
\&   alias_code(ALIAS,CODE [,CODESET]);
\&   rename_country_code(CODE,ALIAS [,CODESET]);
.Ve
.Sp
and the latter should be used for consistency.
.Sp
The alias_code function is deprecated and will be removed at some point
in the future.
.Sp
\&\fBNote:\fR this function was previously called _alias_code, but the
leading underscore has been dropped. The old name was supported for
all 2.X releases, but has been dropped as of 3.00.
