<div>Thank you very much for your help. </div> <div> </div> <div>I wish I knew what I had to tried beforehand. It's just like asking someone who doesn't know Russian alphabet to look up the Russian dictionary first before asking a Russian word.</div> <div> </div> <div>One more question: How to implement his/her own symbol created by using Metapost to the Latex math environment without using \includegrphics commend. For example, first draw a triangle with Metapost and define such as \owntriangle and use it in Latex document.</div> <div> </div> <div>Again, this might be a too easy question for everyone in this group, Taco might scold me again, I am afraid...</div> <div> </div> <div> </div> <div><BR><B><I>Taco Hoekwater <taco@elvenkind.com></I></B> wrote:</div> <BLOCKQUOTE class=replbq style="PADDING-LEFT: 5px; MARGIN-LEFT: 5px; BORDER-LEFT: #1010ff 2px solid">Steve MC Han
