Thanks James, I think I understand now!
Glad to hear it.
Here is another topic:
My, my you are quite the problem child today, aren't you? ;)
What is happening to my second argument here? It is not being passed!
&print_args("abc", $q->param('next'), "xyz");
# However, if make a slight change, it works! my $n = $q->param("next"); &print_args("abc", $n, "xyz");
What is going on here? That was nasty!
Hmm, the only difference I can see between these two calls is the context. The first call is in list context, because of the subroutine call, but the second is scalar context as it is an assignment to a scalar variable. Does it work, if you change the first call to:
print_args("abc", scalar $q->param('next'), "xyz");
??? If that works, it's a context issue.
Consulting 'perldoc CGI' we can see that param() will return an array in list context for multivalued parameters. If that happened I'm guessing you had more entries than you thought in that subroutine call and probably didn't see 'xyz' print out, unless it returned an empty list which I can't think of any reason it would do if you know there's a value in there for the scalar call.
That's my best guess there. If that doesn't help, you need someone who knows more about CGI than me. :D
Good luck.
James
P.S. You don't need those '&' on the sub calls and eventually, they're going to surprise you. Go ahead and drop them.
P.P.S. Your variable names aren't improving, don't make me beat you with the I-Will-Name-My-Variables-Well-Stick! :)
