Hi, i am writing a script that sort elements of an array into certain criteria, and then asks the user what catergory they want to see. I have given a snippet of code here, my problem is that i want to print out every value of a certain criteria when the user asks to see it, however my print statement only prints a single value. Am i not passing the whole array into the scalar variable?? is it because it isn't nested in the loop correctly?? - if i put the whole thing into the loop i end up asking the same question over and over to the user. what am i doing wrong??

#! /usr/local/bin/perl -w

use strict;

my $num_of_params;
$num_of_params = @ARGV;

if ($num_of_params < 2)
{
die ("\n You haven't entered enough parameters !!\n\n");
}       

open (INFILE, $ARGV[0]) or die "unable to open file";

open (OUTFILE, ">$ARGV[1]");

my $line;
my @array;
my $self=0;
my $choice;
           
while (<INFILE>)
{
        $line = $_;
        chomp ($line);

        @array = ();
        @array = split (/\s+/, $line);  

   if (($array[1] =~ /^Happy/) && ($array[2] <30))
    {
    ;
    $self = "$array[1]\t$array[2]\n";

# if i print $self here it prints out all of the results from that cat
+ergory


  }                                            
   
  print STDOUT "Please select the catergory of results that you wish t
+o see;\n\n\t
1.  Hello\n\t2.Happy \n\t3. unhappy
\n\t4.grumpy \n\n";

$choice = <STDIN>;

# remove the newline character from the chosen option.

chomp $choice;

if ($choice eq 1)
{

# if i print $self here it only prints one result, not the entire list

print "$self\n";
 }          

close OUTFILE;

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
