Or 4<<index. I didn't think of that either, and should have done. But it doesn't seem to work. index can be -1, and 4<<(-1) seems to give 0. Of course, 2<<(index+1) is too long. -- Stephen Turner, Cambridge, UK http://homepage.ntlworld.com/adelie/stephen/ "This is Henman's 8th Wimbledon, and he's only lost 7 matches." BBC, 2/Jul/01
