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.
