It isn't needed right now! p...@tui:~/tmp$ cat bar.pl use strict; use warnings; our ($x, $y) = (0,1); *y = \$x; $y = 3; print "\$x = $x and \$y = $y\n"; p...@tui:~/tmp$ perl bar.pl $x = 3 and $y = 3 strict 'refs' only prevents messing around with symbolic references. These are hard references. Phil -- To unsubscribe, e-mail: beginners-unsubscr...@perl.org For additional commands, e-mail: beginners-h...@perl.org http://learn.perl.org/
