Almost, you pass arguments to subroutines, not work on globals. see cgi101/Re: Object Identifier? (red flags, more subs) 
#!/usr/bin/perl --
use strict;
use warnings;
use CGI;
Main( @ARGV );
exit( 0 );
sub Main {
    my $q = CGI->new;
    my( $headers, $body ) = loadPage( $q );
    print $headers, $body;
}
sub loadPage {
    my( $query ) = @_;
    if( authenticate( $q ) ){
        my $page = $q->page || 'default';
        return ThisPage( $pms, $q  ) if $page eq 'thisone';
        return ThatPage( $pms, $q  ) if $page eq 'thatone';
        return DefaultPage( $pms, $q );
    } else {
        return UnauthorizedPage( $pqms, $q );
    }
}
