# Here's one using 'push':
my @array;
push @array, sprintf "%2d", $info;
push @array, sprintf "%3f", $moreinfo;

# Here's another way:
my @array;
$array[0] = sprintf "%2d", $info;
$array[1] = sprintf "%2s", $moreinfo;

# And now you can iterate over the array:
foreach my $item ( @array ) {
    print $item, "\n";
}
