You have created a reference to an anonymous array here, I guess you meant
@a = qw/I LOVE PERL/;
I would like to make a scalar:
$b="I Love Perl\n"
Please don't name variables as $b etc, they make the code unreadable and
read through
Is this okay?
@a=("I","LOVE","PERL");
$i=join(" ",@a);
print $i;

I would like to make a scalar:
$b="I Love Perl\n"
can I do this with a simple one-liner?
