I want to read an array into a flatfile

Please let me know how to do the same
So far this the below code


Code:
 
use strict;
use warnings;
open (my $data , '<', $ARGV[0])|| die "could not open $ARGV[0]:\n$!";
my @array=(<$data>);
my @sorted=sort {(split(/\|/,$a))[2]<=>(split(/\|/,$b))[2]} @array;
print @sorted;

Please let me know how to open the array from a file
I could not understand exactly what you want, but maybe try like this Smilie
Code:
# cat file
3|32|1|4|2
5|4|7|67|12
23|10|45

Code:
# cat justdoit
#!/usr/bin/perl
$n=0;
open("mydata","<$ARGV[0]")||die("Unable to open file -> '$!'");
while(<mydata>){chomp;$n++;
@splitted = split(/\|/);
@sorted = sort { $a <=> $b } @splitted;
print "$n __LINE__ -> ", "@sorted\n";}
close("mydata");

Code:
#./justdoit file
1 __LINE__ -> 1 2 3 4 32
2 __LINE__ -> 4 5 7 12 67
3 __LINE__ -> 10 23 45

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.
