Hi! I'm on Windows 98 at the moment (at work) but I'll try this on my NT machine when
I get home. Here's what I got when I ran your script:
C:\>perl hello.pl
Joe Mary Sue
Use of uninitialized value in concatenation (.) at hello.pl line 5, <STDIN> line
1.
I know .
Got an error but then I got the same results that I've been getting ("I know .").

looks okay too. You must be doing something that you've not posted
here. Is
your print immediately after your stdin? Has your array gone out of
scope.
The following is what you're trying to do, and works on my machince
#!/perl -w
use strict;
my @names;
@names = <STDIN>;
print "I know $names[1].\n";
>
>The output shows "I know ."

What
am I doing wrong? Thanks! :-)
Post more of your prog if us still doesn't work
HTH
