gawk asort to sort record groups based on one subfield
input ("/" delimited fields):
Code:
style1/book1 (author_C)/editor1/2000
style1/book2 (author_A)/editor2/2004
style1/book3 (author_B)/editor3/2001
style2/book8 (author_B)/editor4/2010
style2/book5 (author_A)/editor2/1998

Records with same field 1 belong to the same group.
Using asort (not sort), in each group I need to sort the records in ascending order based on the string between braces in field 2, to obtain:
Code:
style1/book2 (author_A)/editor2/2004
style1/book3 (author_B)/editor3/2001
style1/book1 (author_C)/editor1/2000
style2/book5 (author_A)/editor2/1998
style2/book8 (author_B)/editor4/2010

I tried to sort the records by field1 and then by subfield2 in field2, but it didn't work:
Code:
BEGIN{FS=OFS="/"}

{
    array[$1] = $0

    split ($2, aut, " ")

    asort(array)

    o = asort(aut)

    for (o in aut)
        print array[aut[o]]

}

locale::currency

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

NAME

       Locale::Currency - standard codes for currency identification

SYNOPSIS

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