I have contacted the program dev who changed their code from cerr to cout and now i can get the output. Please advice if there is anything more need to be done to optimize this code 
!/usr/bin/perl -w
use strict;
use warnings;
use Data::Dumper;

my @output = `./retrieve 2301`;
chop @output;

my ($name, $status, $cid);
my %vars = (
    'NAME' => \$name,
    'CID'  => \$cid,
    'STATUS' => \$status,
);

for my $line (@output) {
    my ($key, $val) = split /:/, $line, 2;

    if ($vars{ $key }) {
        ${ $vars{ $key } } = $val;
    } else {
        warn "Unknown key '$key', discarded";
    };
};

my $myID= ${ $vars{ CID } };
my $myStatus=${ $vars{ STATUS } };
my $myName=${ $vars{ NAME } };

print "My name is $myName with status $myStatus ID $myID\n";
