revGoURL in same window

[RGould8 at aol.com]

Well, I'm almost there - - - if the user's default browser happens to be 
Internet Explorer, I can do this to load different web-pages into the same window 
via Applescript...

tell application "Internet Explorer"
     GetURL "http://www.apple.com"
end tell

I'm looking into Safari now to see if it has the same solution.   Apparently 
GetURL is an IE thing.
