Hi MissPerl,

Your question is not very clear, but let's say that you mean you want to loop through two lists of things at the same time. You could store the things in two arrays and use the same index on each array as you go through the loop. That seems to be what you were trying to do. 

my @names = ('Fred', 'Wilma', 'Barney', 'Betty');
my @ages = ( 40, 38, 42, 41 );

for my $i ( 0 .. 3 ) {
    print "$names[ $i ] is $ages[ $i ]\n";
}

... but you'd be better off storing your data in a hash, then you don't have to worry about keeping the index the same, or if the lists get out of order: 
my %flintstones = (
    Fred   => 40,
    Wilma  => 38,
    Barney => 42,
    Betty  => 41,
);

for my $name ( keys %flintstones ) {
    print "$name is $flintstones{ $name }\n";
}

Hope this helps!


The way forward always starts with a minimal test.
