Perl Doubt

["Adityan Murthy" <ad_it@xxxxxxxxxxx>]

Hi All!

I've just started learning perl.

I have a file called read_art.pl which takes a parameter for the name of the 
file and reads the article.  i want to have a rate this article link which 
rates it. for that, i plan to write a file, say rateit.pl now, when i click 
on rate it, it will call the perl file, say as, rateit.pl?val=2 (2 is the 
name of the article file). this file (rateit.pl) will contain the form 
required to rate it. now i want the same file to create the form and do the 
rating. that means that when i rate, it will call rateit.pl?val=2&rating=5.  
so, how do i make the same pl file distinguish the two diff calls?

Also, what is "use CGI"?  Seems similar to creating an object of a class in 
C++.  Where do i get info on the various functions in CGI?

Thanx in advance.
