And, wouldn't it make sense to have different codes for different errors?
Indeed. I've just added them. Smilie



Such a simple solution. Thanks so much.

locale::codes::currency

Locale::Codes::Currency(3pm)				 Perl Programmers Reference Guide			      Locale::Codes::Currency(3pm)

NAME

       Locale::Codes::Currency - standard codes for currency identification

SYNOPSIS

	   use Locale::Codes::Currency;

	   $curr = code2currency('usd');     # $curr gets 'US Dollar'
	   $code = currency2code('Euro');    # $code gets 'eur'

	   @codes   = all_currency_codes();
	   @names   = all_currency_names();

DESCRIPTION

       The "Locale::Codes::Currency" module provides access to standard codes used for identifying currencies and funds, such as those defined in
       ISO 4217.

       Most of the routines take an optional additional argument which specifies the code set to use. If not specified, the default ISO 4217
       three-letter codes will be used.

SUPPORTED CODE SETS

       There are several different code sets you can use for identifying currencies. A code set may be specified using either a name, or a
       constant that is automatically exported by this module.

       For example, the two are equivalent:

	  $curr = code2currency('usd','alpha');
	  $curr = code2currency('usd',LOCALE_CURR_ALPHA);

       The codesets currently supported are:

       alpha, LOCALE_CURR_ALPHA
	   This is a set of three-letter (uppercase) codes from ISO 4217 such as EUR for Euro.

	   Two of the codes specified by the standard (XTS which is reserved for testing purposes and XXX which is for transactions where no
	   currency is involved) are omitted.

	   This is the default code set.

       num, LOCALE_CURR_NUMERIC
	   This is the set of three-digit numeric codes from ISO 4217.

ROUTINES

       code2currency ( CODE [,CODESET] )
       currency2code ( NAME [,CODESET] )
       currency_code2code ( CODE ,CODESET ,CODESET2 )
       all_currency_codes ( [CODESET] )
       all_currency_names ( [CODESET] )
       Locale::Codes::Currency::rename_currency  ( CODE ,NEW_NAME [,CODESET] )
       Locale::Codes::Currency::add_currency  ( CODE ,NAME [,CODESET] )
       Locale::Codes::Currency::delete_currency  ( CODE [,CODESET] )
       Locale::Codes::Currency::add_currency_alias  ( NAME ,NEW_NAME )
       Locale::Codes::Currency::delete_currency_alias  ( NAME )
       Locale::Codes::Currency::rename_currency_code  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Codes::Currency::add_currency_code_alias  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Codes::Currency::delete_currency_code_alias  ( CODE [,CODESET] )
	   These routines are all documented in the Locale::Codes::API man page.
