	As I understand it, there is no practical difference between -tsset-  
and -xtset- currently.  (If that turns out to be incorrect, I'm sure  
someone else will pipe in.)  -xtset- was introduced in an update to  
Stata 9, hence it is not in your [XT] manual if it's an early  
printing.  -help xtset- will provide more information.  Search -help  
whatsnew- for -xtset- to can learn a little about the story behind  
its introduction.

	Hope this helps.
