<h3> Please note: <br>Apparently you are using a rather old version of an internet browser program which is not able to display so-called "frames"! However, the Logic Notation Guide website contains frame structures on almost all its pages, so you won't be able to see these pages with the browswer you are currently using. If possible, you should get an up-to-date version of Netscape or Microsoft's Internet Explorer to view the Logic Notation Guide pages. <br> </h3> (You can find these programs at the <a href="http://www.netscape.com/computing/download/">Netscape</a> or <a href="http://www.microsoft.com/downloads/">Microsoft</a> websites.) <br> <br> <h3> To still get some information about Johannes Prischl right now, please click <a href="JP_mainpage_e.htm">here</a>. <br> However, some of the links on that page might not work since they refer to other pages that use frames again. </h3>
