Do not assume that $_ is a single line of input.
Although $_ is often used to hold the current line of input,
this is not necessarily the case. I should have been more clear,
but in question 3, I intended that $_ might include newlines.
For example, the following Perl fragment would read an entire file
into $_:
while ($line = <>) {
$_ = $_ . $line;
}
Pattern matches always work on $_ by default, however, if no other
variable is specified.
Sorry, I should have said HTML anchor element -- e.g.,
<A HREF="http://www.cs.utk.edu/~cs494/">CS494 Home Page</A>
Hope this clarifies question 3.
Don't hesitate to ask if you have further questions.
