One possible problem is that $alllines is not the same variable as @alllines. Perl would let you know of such things if you use this code:

Code

use strict; 
use warnings;

Also, you should use print instead of printf in your code.

In addition:

1) Search google for 'code tags'. Read the first 10 results and come back and post what you have learned.

2) Start all your programs with the following lines:

Code

use strict; 
use warnings; 
use 5.010;  #if using perl 5.10+

3) Declare all variables with my(), e.g.:

Code

my $num; 
my @numbers; 
my($num1, $num2) = (3, 4); 
my %phone_number_for;

4) Use the 3-arg form of open(), and use a variable instead of a bareword filehandle:

Code

open my $INFILE, '<', 'data.txt' 
    or die "Couldn't open data.txt: $!";

You probably mean to use print rather than printf. printf requires a format.
Good Luck,
Bill
