hi, Thank you for replying! I sort of understand what you've done but the phone models are read from a text file and they can vary from anything from a few models to loads more so i cant hard code that into the code, can that be adapted into the coding? I'm currently using this array for the list of all the colours:

 @colours =  ( "baby blue", "baby pink", "black", "dark blue", "brown"
+, "dark purple", "green", "orange", "hot pink", "light purple", "red"
+, "white", "yellow");
foreach $colour (@colours) {
print $colour;
}

I hope this makes sense?

to simply, how do i adapt the following: @phones=qw(iph1 iph2 iph3); so that it reads the phone titles from the text file:

chomp $results;
push (@oid,$results[0]);
    $_ = defined($_) ? $_ : '' for @results;

I hope that makes sense?

Formally, you want the cross product of the set of models and the set of colors. The post by cheekuperl shows how to do this. It does not know or care where the sets came from.

The only remaining question is how to parse the phone file and store the models into the array @phones. You have not given us enough detail about the file to help you with this. Does it have one phone per line? If not, how are the models seperated? Should whitespace be removed?, etc

Hi Bill, I apologize for not being clear, cheekuperl provided a great solution however the list of phone models are in a text file called mobiles.txt there are several columns In the text file however the phone models will always be in the first column, the phone models need a color assigned to them which can be retrieved via the colpr array, the phone models are one per line in the first column some models have white space e.g Nokia 8250 or Samsung galaxy nexus etc I hope this reply is insightful?? Thank you :-)

Put list of colours in __DATA__ where it can easily be changed. Get the name of the phone file from the command line. Extract the model from each record of the file with a regular expression. (My regexp assumes that the 'columns' are seperated by TABs.) The processing is the same as before.

use strict;
use warnings;
use Readonly;
#  Assume input file name on command line (default is 'phones.txt).
Readonly::Scalar my $PHONE_FILE => $ARGV[0] || 'phones.txt';
Readonly::Array my @COLOURS => <DATA>;
#  Assume columns seperated by tabs, all other whitespace is significa
+nt.
Readonly::Scalar my $GET_MODEL => qr{\A ( [^\t]+ ) }x;

open my $PHONES, '<', $PHONE_FILE or die "Cannot open $PHONE_FILE\n";

while (my ($phn) = <$PHONES> =~ $GET_MODEL) {
    foreach my $colr (@COLOURS) {
            print "\n$phn $colr";
    }
    print "\n===";
}
close $PHONES
__DATA__
baby blue
baby pink
black
dark blue
brown
dark purple
green
orange
hot pink
light purple
red
white

Note: Readonly is not necessarey. Its purpose here is to assure the reader that those symbols are logically constants.
