You're right, of course, about the quotes. It seems to me that this is the downside of Perlish convenience. Since Perl offers variable interpolation within double quotes, this can be very confusing to a novice. Of course, since the facility is there, I use it. Still, I tend to look at such constuctions as: print "Hello, $User, how are you doing?\n"; as: print "Hello, " . $User . ", how are you doing?\n"; which, as the error messages returned when $User is undefined make clear, the way the interpreter handles it internally--it sees the string in the first line as the concatenation shown in the second.
