when using a frameset, the code below would set the frame names:
<!-- frames -->
<frameset cols="23%,*">
<frame name="left" src="left.html" marginwidth="10" marginheight="10" scrolling="no" frameborder="0">
<frame name="right" src="right.html" marginwidth="10" marginheight="10" scrolling="auto" frameborder="0">
</frameset>
with the left frame being name "left" and the right frame being named "right". When writing links in your html files that are used "left.html" and "right.html" you would add a target in this case going from left to right as below:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<html>
<head>
<title>Untitled</title>
</head>
<body bgcolor="Black">
take me to Altavista <a href="
target="right">click here</a>:
</body>
</html>
notice in my link the target="right" which is what I named the right frame. You can use this with all of your links in your HTML files. Just remember to use the right name (whatever you called your right side in the frameset). and remember that if you want to open a new window, you could simply set the target to "blank".
Hope this helped
