I'm messing around with trying to link to different sections in a script, so that I can click on a link (ie. script.cgi?abc, and &abc; will run). It works, but with some *issues*.

#!perl -w
use strict;
use CGI;
use CGI::Carp qw(fatalsToBrowser); #errors will show in browser

my $q = new CGI;

print qq!
<a href="script.cgi?one">one</a>
<br>
<a href="script.cgi?two">two</a>
<br>
<a href="script.cgi?three">three</a>
!;

if($q->param){
    my $sub = $ENV{'QUERY_STRING'};
    if(defined &$sub){
        print "<BR><BR>";
        &$sub;
    }else{
        print "<BR><BR>";
        &error;
    }
}

sub one {
    print "sub... one";
}

sub two {
    print "sub... two";
}

sub three {
    print "sub... three";
}

sub error {
    print "ERROR\!\!";
}

If you comment out 'use strict;', this will work with no problems... but with strict on, it won't allow me to use the call &$sub;. Is there an easy way to get around that problem? Also, is there an easier way of doing what I'm trying to do here? (in that above code, I know that I can take off if($q->param) { }, however I'll be needing it later, so I just left it =P

Any help would be appreciated.
