Okey, lower case code tags don't work. Noted. Lets try that again:

  my $word = shift @ARGV;

  open my $fh, 'WikiWikiList';

  sub flup {
    my $start = shift;
    my $stop = shift;
    my $mid = int(($start + $stop) / 2);
    return 0 if $start == $mid or $stop == $mid;
    seek $fh, $mid, 0;
    <$fh>;
    my $line = <$fh>; chomp $line;
    print "debug: $start -> $mid -> $stop  cmp: ", ($word cmp $line), 
+"   $word vs $line\n";
    return flup($start, $mid) if(($word cmp $line) == -1);
    return flup($mid, $stop) if(($word cmp $line) == 1);
    return 1;
  }

  if(flup(0, -s $fh)) {
    print qq{\xb7 Other Wikis: <a href="http://c2.com/cgi/wiki?$word">
+$word on WikiWiki</a><br><br>\n};
  }
