in reply to Re: Or Operator
in thread Or Operator
I think this is the clearest and most concise way to express it:
my $page = $cgi->param("page") || "login";
You might say that inexperienced people won't understand it, but once they see it a few hundred times (because this is a very common way of doing it), they'll probably get it. |

Then again, if there is a chance that $cgi->param("page") will be 0 - and you want to accept that, || will not work correctly. We'll get // (defined-or) in Perl 5.10, fortunately. | [reply]
