There are 2 ways. One by using the CGI.pm or the other one is by using the $ENV{'QUERY_STRING'}.

(1)

#!/usr/bin/perl -w

use CGI qwall);

print header;

$username = param('username');

Now you can access the variable by doing the following:

script.cgi?username=yourname.

(2)

#!/usr/bin/perl -w

print "Content-type: text/html\n\n";

$query = $ENV{'QUERY_STRING'};

if ($query =~m/variable/) {
print "Welcome to section 1";
exit;
}else{
print "Query String Error";
exit;
}

How is script.pl "trying" to recognize the variable that is being passed to it?

AaronGeorge: you forgot about the POST method. It puts the values in STDIN where you have to read them.

jimmy: if you're calling the program from itself, there are several ways to pass parameters. If you make the part of the program you want to call again a subroutine, you can just call it recursively and pass the parameter in the usual way. If you're calling it via a command line call, you can pass the parameter in the command line and get at it using the ARGV array. You can also call it using the "do" command and pass the value via a global variable. Tracy Dryden

Tracy, I think jimmy is just trying to POST(or link?) back into the same script - I was trying to get jimmy to tell us exactly what method he is using(POST, GET, ?) to direct the script back into itself, and also what method he is using in script.pl to recognize incoming parameters. I don't think he's actually trying to recursively call the same script, or subroutine within the same script. Maybe I'm wrong?
