It really would help if you could build sentences. Sentences are terminated by a single dot ("."). There should be no whitespace before punctuation, but one space after.

Anyway, the thing you are looking for is $_.

foreach (@array) {
    print $_;
}

prints each element. You can also assign the elements to a variable like this:

foreach my $line (@array) {
    print $line;
}

I have no idea what you could mean with your second question.
