Thanks. Is this better?
print "$first, $second, $third","\n"; 255, 255, 255 765 If I put the second set of quotes after the last comma, I get an error. I am only on pg 21 of Learning Perl 5th ed. I am trying as many variations of the examples just to mess around and see what happens with different characters.

The "\n" must be placed inside a string.
