Code:
$i = $i != "" ? $i : (i == 2 || i == 3) ? "ND" : " "

Here it checks if $i not equals to null (""). If True then $i keep it as it is. If false then check i == 2 OR 3 if true then set $i="ND" and if false then set $i=" ".

If i got it your requirement right. You want all the values which is not present to null. and keep null value as it is.
try
Code:
$i = $i != "" ? $i:""

OR

Code:
awk -F '"' '
NR > 1{    for(i = 1; i <= NF; i += 2) gsub(/,/, "|", $i)
    print
}' OFS="" file | awk 'BEGIN{FS = OFS = "|"}
{    for(i = NF+1; i <= 20; i++)
        $i="";
    print
}'

locale::currency

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

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. The ones currently supported are:

       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 code set is identified with the symbol "LOCALE_CURR_ALPHA".

	   This is the default code set.

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

	   This code set is identified with the symbol "LOCALE_CURR_NUMERIC".

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 man page.
