Quite expected response. :)

Here is the Perl code:

--->8--- begin perl code --->8---

open(FH, "Koleksi.dat") or die("Koleksi.dat: $!");
$/ = "</DOC>\n";
while (<FH>) {
   while (m/<(TITLE|TEXT)>(.+)<\/\1>/gcs) {
     $str = lc $2;
     while ($str =~ m/\b([a-z]+)\b/gcs) {
print "Word count: $jum_kata\n";
print "Unique word count: ", scalar keys %arr_kata, "\n";

--->8--- end perl code --->8---

The compressed "Koleksi.dat" file can be obtained from 
http://wawan.web.id/text/Koleksi.zip (957 KB). It's actually an HTML 
document taken from somewhere. Using time command as simple profiler, 

bee at ubuntu:~$ time perl koleksi.perl

Word count: 126944
Unique word count: 11793

real    0m0.203s
user    0m0.196s
sys     0m0.004s

Tested on Ubuntu (gutsy) with on IBM x60 (1.8 GHz processor and 1 GB 

The pascal counter-part resulting almost twice slower. Though not as 
simple as Perl, the pascal code is quite simple and only using standar 
fpc's units. But, I won't post the code here to not influence your logic. ;)

Just try to beat it. I expect you'll only use basic or default fpc's 
units. :)

Understood. But newbies or newcomers won't write the wrappers by 
themselves in the first place unless it's already provided by the tool
