in thread Scoping Variables

Ahem, er, am I missing something really simple here?
I wouldn't expect this statement to work:- 
if ($foo) {
            print "the date is... $date \n <br>";
         }

at least not on my Perl version.

Surely, it should be:-
if ($foo) {
            print "The date is...", $date, "\n <br>";
         }

    Yes, you are missing something really simple here. It's called interpolation and it happens inside double quotes. Put this in a script and run it. $x=1; print 'single quoted dollar x is $x'; print "\n"; print "double quoted dollar x is $x"; print "\n"; perl -e '

      WHOOPS, Sorry. That should have been 
      $x=1;
print 'single quoted dollar x is $x';
print "\n";
print "double quoted dollar x is $x";
print "\n";

      Many thanks.
      Neither of my enormous tomes containing Perls of wisdom explained that one!
