Thanks for your responses ! Maybe I will prospect in direction of CLIPS + TclCLIPS ...<br> <br> In response to Mark: Unfortunately i'm quite new in XOTcl and really new to rules engines, RETE and so on ... My goal was to study them using Tcl/XOTcl (better I think ;) that I really prefer to java for quick development/tests/scripting (and many other good reasons ;) so hmm no ... I don't think I will plan to write an implementation of the RETE algorithm in XOTcl in a next future ... ;)<br> <br> Regards,<br> Luc Rasson<br><br><br><b><i>Andreas Kupries &lt;andreask@activestate.com&gt;</i></b> wrote:<blockquote class="replbq" style="border-left: 2px solid rgb(16, 16, 255); margin-left: 5px; padding-left: 5px;">   <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"> <meta content="MSHTML 6.00.6000.16525" name="GENERATOR"> <div><font color="#0000ff" face="Arial" size="2"><a href="http://wiki.tcl.tk/8365">http://wiki.tcl.tk/8365</a></font></div> <div><span
