Perl Function Array Arguement Passing

Hi All,

I have some questions regarding array arguements passing for Perl Function.
If @array contains 2 items , arguements passing would be like Code_A.
But what if @array needs to add in more items, the rest of the code like $_[some number] will have to be modified as well (highlighted in red), which is very troublesome, just like in Code_B where 1 more item is added to @array. Is there an easier way to overcome this problem ?

Code_A

Code:

#!/usr/local/bin/perl

my @array = ( "AAA" , "BBB" );


Generic( @array , "WE" , "HIGH" , "DOWN" );


sub Generic {
	foreach my $file ( $_[0] , $_[1] ) {
		print "Now Processing $file ...\n";
	};

	print "$_[2]\n";
	print "$_[3]\n";
	print "$_[4]\n";

}

Code_B

Code:

#!/usr/local/bin/perl

my @array = ( "AAA" , "BBB" , "CCC");


Generic( @array , "WE" , "HIGH" , "DOWN" );


sub Generic {
	foreach my $file ( $_[0] , $_[1] , $_[2]) {
		print "Now Processing $file ...\n";
	};

	print "$_[3]\n";
	print "$_[4]\n";
	print "$_[5]\n";

}

collator_sort

COLLATOR_SORT(3)							 1							  COLLATOR_SORT(3)

Collator::sort - Sort array using specified collator

	Object oriented style

SYNOPSIS

       public bool Collator::sort (array  &$arr, [int  $sort_flag])

DESCRIPTION

	Procedural style
       bool collator_sort (Collator  $coll, array  &$arr, [int	$sort_flag])

       This function sorts an array according to current locale rules.

	Equivalent to standard PHP sort(3) .

PARAMETERS

	      o $coll
		-Collator object.

	      o $arr
		- Array of strings to sort.

	      o $sort_flag
		- Optional sorting type, one of the following:

		     o Collator::SORT_REGULAR - compare items normally (don't change types)

		     o Collator::SORT_NUMERIC - compare items numerically

		     o Collator::SORT_STRING - compare items as strings

	       Default sorting type is Collator::SORT_REGULAR. It is also used if an invalid $sort_flag value has been specified.

RETURN VALUES

	Returns TRUE on success or FALSE on failure.

EXAMPLES

       Example #1

	      collator_sort(3) example

	      <?php
	      $coll = collator_create( 'en_US' );
	      $arr  = array( 'at', 'as', 'as' );

	      var_export( $arr );
	      collator_sort( $coll, $arr );
	      var_export( $arr );
	      ?>

	      The above example will output:

	      array (
		0 => 'at',
		1 => 'as',
		2 => 'as',
	      )array (
		0 => 'as',
		1 => 'as',
		2 => 'at',
	      )
