So I am about switch phones, but panasonic cant get the 200+ phone numbers I have saved on my phone to the new one, so I wrote this program to create a text file of all the names in the phone book and their numbers, that way i can create a program to parse the output and (granted manually) enter them into the new one.The problem, however, is some numbers in my phone book only have a first name, not a first and a last, (i.e. "Doctor" or "school") and so I assign a 0 to that field. When I go to write the data I get a uninitialized value error at line 45 if ($2 =~ /^0$/) {, which doesnt make any sense to me since $2 is defined as 0. Anyway here is the code, if anyone has a clue what is going on, thanks alot! thans alot anyway

#!/usr/bin/perl -w
use strict;

my (@def, %char, $cont, $field, @info, %book, $file, $name, $i);

@def = qw\ first_name second_name work_number home_number cell_number 
+\; #fields
%char = (               #regex for each field
    'first_name' => '^[a-z]+$',
    'second_name' => '^[a-z]*$',
    'work_number' => '^([0-9]{3}-|)[0-9]{3}-[0-9]{4}$',
    'home_number' => '^([0-9]{3}-|)[0-9]{3}-[0-9]{4}$',
    'cell_number' => '^([0-9]{3}-|)[0-9]{3}-[0-9]{4}$'
);
$cont = 1;

while ($cont == 1) {
    @info = ();
    foreach $field (@def) {
        print "$field: ";
        $_ = <>;
        chomp;
        unless ($_) {     #if no input then field = 0
            push @info, "0";
            next;
        }
        while (!/$char{$field}/i) {    #check format
            print "error: $_: invalid format: $char{$field}\n";
            print "$field: ";
            $_ = <>;
            chomp;
            unless ($_) {
                push @info, "0";
                next;
            }
        }
        push @info, lc($_);
    }
    for (2 .. $#info) { #create hash of array of data, key = first nam
+e & last name
        push @{ $book{$info[0] . "&" . $info[1]} }, $info[$_];
    }
    print "another entery? (*/n)";
    $_ = <>;
    chomp;
    $cont = 0 if /n/i;
}

print "Save where? ";
$file = <>;
chomp $file;

open (BOOK, ">$file") or (die "Can't open $file: $!");

foreach $name (keys %book) {   #write the data
    $name =~ /(.+)&(.+)/;
    if ($2 =~ /^0$/) {
        print BOOK "$1,::";
    } else {
        print BOOK"$1,$2::";
    }
    for ( 0 .. $#{ $book{$name} } ) {
         print BOOK $def[$_+2] . ":" . $book{$name}[$_] . "::" unless 
+$book{$name}[$_] =~ /^0$/; #print field name then data unless the fie
+ld is empty
    }
    print BOOK "\n";
}
close(BOOK);
