yeah.

I've got code written with the oo CGI interface, and code written with the function CGI interface. trimParameters sits between these two different sets of files. That's why trimParameters takes $q (it ususally sits in a .pm file). It takes $q from the oo code, and $CGI::Q from the function oriented code.

But, clearly, I do not understand how to use the function oriented CGI module, and how $CGI::Q is initialized.

By my understanding, if I do my $q = CGI->new, I get two objects, a local object referred to by $q, and a global object that is automatically used in function mode, and can be directly accessed by $CGI::Q. If, on the other hand, I do not do $q=CGI->new, I still get the default cgi object, $CGI::Q
