You forgot the comma:

push @array, [$first, $last, $address, $city, $zip];

By the way, from looking at your printing loop, [] might not do what you expect it to. [] creates an anyonomous array (see perlref), and it won't print anything useful in your loop. To see what I mean, try:

while(<DATA>) {
  push @array, [$first, $last, $address, $city, $zip];
}

foreach (@array){
  print "@$_\n";
}
[download]

You mean have wanted the following, which pushes the elements onto the array linearly:

push @array, $first, $last, $address, $city, $zip;
