CGI.pm post types

I see on the CGI web page that this:
===================================
use CGI;

$q = new CGI;

$query = $q->param( 'POSTDATA' );
===================================

will return the contents of this URI:

http://server/cgi.cgi?POSTDATA=posteddata

How do I code so that I don't have to use POSTDATA?

I know it's a silly question and probably obvious, but not to me

Thanks

In this case "$query" will return "posteddata", the value of the HTTP
parameter of POSTDATA (a "GET" one in this case.).

What do you want to do exactly?

Well, I thought something I was looking at implied I didn't have to use
name/value pairs. I got out my handy dandy sniffer and it appears I was
utterly incorrect... Unless you tell me otherwise :)

Well, you can always use PATH_INFO:

http://myhost.tld/cgi-bin/my.cgi/more/path/here/

And retrieve it using $cgi->path_info().

Is this what you are looking for?

It was you who defined the variable name, i.e. POSTDATA. You can change the name to something else.

Or are you trying to get rid of the key value pairs entirely? That unfortunately won't work since HTTP is a 'stateless' protocol and if you want the remote machine to calculate something with your input you'll have to provide input and key value pairs is the way its done.
