This makes a lot of sense and I think it may be the solution BUT my Ctr-z isn't
working on my machine! I'm on Win98 and when I press ctrl-z it goes to a DOS prompt
(no output). Any ideas on fixing this? If not, I can try this on my NT machine at
home.

Hi Anthony,
LF (\n) is the default record separator, so if you type 3 names and
press
enter,
all 3 names get placed in $array[0].
The next item(s) get placed in $array[1], etc depending on where you
press
enter.
If your input looks like this:
Fred Barney <enter>
Wilma Betty <enter>
your program will print "Wilma Betty" because each <enter> will add a
LF.

I typed in 3. For example, "Sam Mary Joe". I expect to get "I know
Mary",
since she's [1] but I'm getting a blank space. I've tried this on NT
and on
my 98 machine here at work.

How many names did you type in? $names[1] is the
second
element of the
array because arrays start at zero by default, so you
will
need to type in
at least two names.
