Hi Perl Monks! I'm trying to use array elements in a file search. This is what I've written thus far. I want the script to be able to go through each array element and then search for that particular element in a file. My logic (to me) seems right, but I feel that I'm missing a fundamental concept.

This is the infile.

#INFILE
A
B
C
D

This is the code.

#!usr/bin/perl5.8.8

use strict;
use warnings;

my @array = qw (A B C D);
open (my $INFILE,"<", "letters");
open (my $OUTFILE,">", "capturedletters");

my $Letter;

foreach my $i (@array)
{
print "Foreach loop$i, ";
print "\n";
        while (<$INFILE>)
        {
        print "While loop$i, "; #this variable does not change
    
            if ($_ =~/^$i/)
            {
            print $OUTFILE "$_";
            }
        }
    
}

close ($INFILE);
close ($OUTFILE);

This is the output I get. 

Foreach loopA, 
While loopA, While loopA, While loopA, While loopA, Foreach loopB, 
Foreach loopC, 
Foreach loopD,

Thanks!
