I get the error "readline() on closed filehandle $INFILE at Fileappendor.pl line 20."

This is a simple example of my problem. I can't seem to figure it out. Even if I don't ever close the filehandle, I still get the error. I feel like this is a conceptual newbie mistake. Can someone please address what I'm doing wrong? Thanks in advance. 

#!usr/bin/perl5.8.8

use strict;
use warnings;

fileappendor();

sub fileappendor
{
my $fileno = 1;
my $outfile = "proteintable";

open (my $OUTFILE,">", $outfile);

while($fileno <= 152)
{
my $infile = $fileno."_FamDATA";
open (my $INFILE,"<", $infile);

    while(<$INFILE>)
    {
    print $OUTFILE $_;
    }

close ($INFILE);
$fileno++;
}
} #end of sub fileappendor
