!~ will return true if the thing on the right does not match.
In your case, however, using unless seems more logical. Something like
exit unless (lc($answer) =~ /^[y|yes]$/)
should work. The ^ and $ are there to make sure that the string
contains nothing but ``y'' or ``yes''. Make sure that you
To push something to an array:
push(@array, $data);
To push something onto a scalar:
$scalar = $scalar . $data;
-or-
$scalar .= $data;
The better method depends entirely on what you intend to do with the
data and how you have it. It is also very easy to both split a string

through the array and comparing each element to the item in question?

Look up grep.
You might be wanting a hash table not an array.
