Take a look at perldoc -- it does paging while running, using a temporary file. The meat of the thing is this little sub:

sub page {
    my ($tmp, $no_tty, @pagers) = @_;
    if ($no_tty) {
        open(TMP,"<", $tmp)     or die "Can't open $tmp: $!";
        local $_;
        while (<TMP>) {
            print or die "Can't print to stdout: $!";
        }
        close TMP               or die "Can't close while $tmp: $!";
    }
    else {
        foreach my $pager (@pagers) {
            last if system("$pager $tmp") == 0;
        }
    }
}

The good perldoc tries to use an array of pagers, depending on system type (Win32, VMS, DOS, OS2, and of course *N*X), and even has a flexible idea of what a pager _is_ (notepad is one option for Win32).

Now, if there is a module doing the same kind of thing, or if someone were to make one -- I would like to know :-)

If I understand your problem right, you should be able to find what you need in the perldoc source. How is that for irony? perldoc teaching you programming techniques! :-)
