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";

Post more of your prog if us still doesn't work
